Van Rompaey, Robbe, Moonen, Marc.  2021.  Distributed Adaptive Acoustic Contrast Control for Node-specific Sound Zoning in a Wireless Acoustic Sensor and Actuator Network. 2020 28th European Signal Processing Conference (EUSIPCO). :481–485.
This paper presents a distributed adaptive algorithm for node-specific sound zoning in a wireless acoustic sensor and actuator network (WASAN), based on a network-wide acoustic contrast control (ACC) method. The goal of the ACC method is to simultaneously create node-specific zones with high signal power (bright zones) while minimizing power leakage in other node-specific zones (dark zones). To obtain this, a network-wide objective involving the acoustic coupling between all the loudspeakers and microphones in the WASAN is proposed where the optimal solution is based on a centralized generalized eigenvalue decomposition (GEVD). To allow for distributed processing, a gradient based GEVD algorithm is first proposed that minimizes the same objective. This algorithm can then be modified to allow for a fully distributed implementation, involving in-network summations and simple local processing. The algorithm is referred to as the distributed adaptive gradient based ACC algorithm (DAGACC). The proposed algorithm outperforms the non-cooperative distributed solution after only a few iterations and converges to the centralized solution, as illustrated by computer simulations.

Wireless Sensor Network (WSN) is considered as the backbone of Internet of Things (IoT) networks. Authentication is the most important phase that guarantees secure access to such networks but it is more critical than that in traditional Internet because the communications are established between constrained devices that could not compute heavy cryptographic primitives. In this paper, we are studying with real experimentation the efficiency of HIP Diet EXchange header (HIP DEX) protocol over IPv6 over Low Power Wireless Personal Area Networks (6LoWPAN) in IoT. The adopted application layer protocol is Constrained Application Protocol (CoAP) and as a routing protocol, the Routing Protocol for Low power and lossy networks (RPL). The evaluation concerns the total End-to-End transmission delays during the authentication process between the communicating peers regarding the processing, propagation, and queuing times' overheads results. Most importantly, we propose an efficient handshake packets' compression header, and we detailed a comparison of the above evaluation's criteria before and after the proposed compression. Obtained results are very encouraging and reinforce the efficiency of HIP DEX in IoT networks during the handshake process of constrained nodes.

A continually growing number of sensors is required for monitoring industrial processes and for continuous data acquisition from industrial plants and devices. The cabling of sensors represent a considerable effort and potential source of error, which can be avoided by using wireless sensor nodes. These wireless sensor nodes form a wireless sensor network (WSN) to efficiently transmit data to the destination. For the acceptance of WSNs in industry, it is important to build up networks with high trustworthiness. The trustworthiness of the WSN depends not only on a secure wireless communication but also on the ability to detect modifications at the wireless sensor nodes itself. This paper presents the enhancement of the WSN's trustworthiness using an optical localization system. It can be used for the preparation phase of the WSN and also during operation to track the positions of the wireless sensor nodes and detect spatial modification. The location information of the sensor nodes can also be used to rate their trustworthiness.

Secure wireless communication is essential for most industrial applications. The secure and reliable control of processes as well as the data integrity of measured values are key targets in these applications. The industrial Internet-of-Things (IIoT) tries to connect an increasing number of sensors wirelessly. The wireless sensors form wireless sensor networks (WSNs). However, wireless sensor nodes are exposed to various security threats ranging from physical modification on the device itself to remote attacks via the communication channel. It is important to secure the complete lifetime of the wireless sensor nodes and other system components. This includes the production phase, shipping, preparation phase and operational phase. This paper presents a lifetime security concept for a wireless sensor network applied in automotive test beds. In this application scenario, the wireless sensor nodes are used to capture various temperatures in an automotive unit under test. In order to indicate the current state of trustworthiness of the system, a trustworthiness indicator is implemented which is shown to the user. An evaluation of the impact of encrypted communication on power consumption shows that the increase is negligible, and can be expected to be provided by the wireless sensor node's power supply without reducing the node lifetime.
Belej, Olexander.  2020.  Development of a Technique for Detecting "Distributed Denial-of-Service Attacks" in Security Systems of Wireless Sensor Network. 2020 IEEE 15th International Conference on Computer Sciences and Information Technologies (CSIT). 1:316–319.
A distributed denial of service attack is a major security challenge in modern communications networks. In this article, we propose models that capture all the key performance indicators of synchronized denial of service protection mechanisms. As a result of the conducted researches, it is found out that thanks to the method of delay detection it is possible to recognize semi-open connections that are caused by synchronous flood and other attacks at an early stage. The study provides a mechanism for assessing the feasibility of introducing and changing the security system of a wireless sensor network. The proposed methodology will allow you to compare the mechanisms of combating denial of service for synchronized failures and choose the optimal protection settings in real-time.

In this paper, the structure of wireless sensor network and node localization technology are briefly introduced, and the key technologies of wireless sensor network development are summarized from the four aspects of energy efficiency, node localization, data fusion and network security. As a detection system of perceiving the physical world, WSN is also facing challenges while developing rapidly.
Vasilyev, Vladimir, Shamsutdinov, Rinat.  2020.  Security Analysis of Wireless Sensor Networks Using SIEM and Multi-Agent Approach. 2020 Global Smart Industry Conference (GloSIC). :291–296.
The paper addresses the issue of providing information security to wireless sensor networks using Security Information and Event Management (SIEM) methodology along with multi-agent approach. The concept of wireless sensor networks and providing their information security, including construction of SIEM system architecture, SIEM analysis methodologies and its main features, are considered. The proposed approach is to integrate SIEM system methodology with a multi-agent architecture which includes data collecting agents, coordinating agent (supervisor) and local Intrusion Detection Systems (IDSs) based on artificial immune system mechanisms. Each IDS is used as an agent that performs a primary analysis and sends information about suspicious activity to the server. The server performs correlation analysis, identifies the most significant incidents, and helps to prioritize the incident response. The presented results of computational experiments confirm the effectiveness of the proposed approach.
Mutalemwa, Lilian C., Shin, Seokjoo.  2020.  Improving the Packet Delivery Reliability and Privacy Protection in Monitoring Wireless Networks. 2020 International Conference on Information and Communication Technology Convergence (ICTC). :1083—1088.
Source location privacy (SLP) protection ensures security of assets in monitoring wireless sensor networks (WSNs). Also, low end-to-end delay (EED) and high packet delivery ratio (PDR) guarantee high packet delivery reliability. Therefore, it is important to ensure high levels of SLP protection, low EED, and high PDR in mission-critical monitoring applications. Thus, this study proposes a new angle-based agent node routing protocol (APr) which is capable of achieving high levels of SLP protection, low EED, and high PDR. The proposed APr protocol employs multiple routing strategies to enable a dynamic agent node selection process and creation of obfuscating routing paths. Analysis results reveal that the APr protocol achieves high packet delivery reliability to outperform existing intermediate node-based protocols such as the AdrR and tree-based protocols such as the TbR. Furthermore, the APr protocol achieves significantly high levels of SLP protection to outperform the AdrR protocol.

Fake source packet routing protocols can ensure Source Location Privacy (SLP) protection. However, the protocols have demonstrated some performance limitations including high energy consumption, low packet delivery ratio (PDR), and long end-to-end delay (EED). In this study, a 2-level phantom routing protocol is proposed to address some limitations of an existing fake source packet routing protocol. The proposed protocol supplants the fake source packets with a random second level phantom node to alleviate the limitations. Analysis results confirm that the proposed protocol is capable of achieving strong SLP protection with minimized communication overhead. By removing the fake packet traffic in the network, the protocol incurs minimized energy consumption, maximized PDR, and minimized EED.
Arivarasi, A., Ramesh, P..  2020.  Review of Source Location Security Protection using Trust Authentication Schema. 2020 Third International Conference on Smart Systems and Inventive Technology (ICSSIT). :215—222.
Wireless Sensor Networks promises the wireless network tools that does not require any stable infrastructure. Routing is the most important effect of network operation for the extended data rates within the network. Route discovery and route search sent the required packets from the target node source. However, good data transmission is also a threatening task in networks that provide efficient and energy-efficient routing. Various research activities focus on the topology control, source location privacy optimization and effective routing improvement in WSN. Wherein the existing security solutions both routing protocols and source location solutions disrupt the self-organizing nature of wireless sensor networks. Therefore, large overhead signatures are displayed and digitally verified by the requesting node. The cloud-based and routing based schemes have provided efficient security but there are a lot of obstacles for source data and travel path information security in the WSN network. This study is dedicated to calculate the desired number of deployments for sensor nodes in a given area once the selected metric achieves a certain level of coverage, while maintaining wireless connectivity in the network. A trusted node authentication scheme in wireless sensor network reduces the communication between nodes in a secure data transmission network, where shared cryptography is established all adjacent to the sensor node. Route discovery and retransmission increases the network overhead and increases the average end-to-end delay of the network in the conventional systems. This results in higher time complexity, communication overhead and less security of constrained sensor network resources.

The usage of K-anonymity to preserve location privacy for wireless sensor network (WSN) monitoring systems, where sensor nodes operate together to notify a server with anonymous shared positions. That k-anonymous position is a coated region with at least k people. However, we identify an attack model to show that overlapping aggregate locations remain privacy-risk because the enemy can infer certain overlapping areas with persons under k who violate the privacy requirement for anonymity. Within this paper we suggest a mutual WSN privacy protocol (REAL). Actual needs sensor nodes to arrange their sensing areas separately into a variety of non-overlapping, extremely precise anonymous aggregate positions. We also developed a state transfer framework, a locking mechanism and a time delay mechanism to address the three main REAL challenges, namely self-organisation, shared assets and high precision. We equate REAL's output with current protocols through virtual experiments. The findings demonstrate that REAL preserves the privacy of sites, offers more precise question answers and decreases connectivity and device expense.

With a storage space limit on the sensors, WSN has some drawbacks related to bandwidth and computational skills. This limited resources would reduce the amount of data transmitted across the network. For this reason, data aggregation is considered as a new process. Iterative filtration (IF) algorithms, which provide trust assessment to the various sources from which the data aggregation has been performed, are efficient in the present data aggregation algorithms. Trust assessment is done with weights from the simple average method to aggregation, which treats attack susceptibility. Iteration filter algorithms are stronger than the ordinary average, but they do not handle the current advanced attack that takes advantage of false information with many compromise nodes. Iterative filters are strengthened by an initial confidence estimate to track new and complex attacks, improving the solidity and accuracy of the IF algorithm. The new method is mainly concerned with attacks against the clusters and not against the aggregator. In this process, if an aggregator is attacked, the current system fails, and the information is eventually transmitted to the aggregator by the cluster members. This problem can be detected when both cluster members and aggregators are being targeted. It is proposed to choose an aggregator which chooses a new aggregator according to the remaining maximum energy and distance to the base station when an aggregator attack is detected. It also save time and energy compared to the current program against the corrupted aggregator node.

Data sampling is critical process for energy constrained Wireless Sensor Networks. In this article, we proposed a Predictive Data Recovery Compressive Sensing (PDR-CS) procedure for data sampling. PDR-CS samples data measurements from the monitoring field on the basis of spatial and temporal correlation and sparse measurements recovered at the Sink. Our proposed algorithm, PDR-CS extends the iterative re-weighted -ℓ1(IRW - ℓ1) minimization and regularization on the top of Spatio-temporal compressibility for enhancing accuracy of signal recovery and reducing the energy consumption. The simulation study shows that from the less number of samples are enough to recover the signal. And also compared with the other compressive sensing procedures, PDR-CS works with less time.
Saputra, R., Andika, J., Alaydrus, M..  2020.  Detection of Blackhole Attack in Wireless Sensor Network Using Enhanced Check Agent. 2020 Fifth International Conference on Informatics and Computing (ICIC). :1–4.

Wireless Sensor Network (WSN) is a heterogeneous type of network consisting of scattered sensor nodes and working together for data collection, processing, and transmission functions[1], [2]. Because WSN is widely used in vital matters, aspects of its security must also be considered. There are many types of attacks that might be carried out to disrupt WSN networks. The methods of attack that exist in WSN include jamming attack, tampering, Sybil attack, wormhole attack, hello flood attack, and, blackhole attack[3]. Blackhole attacks are one of the most dangerous attacks on WSN networks. Enhanced Check Agent method is designed to detect black hole attacks by sending a checking agent to record nodes that are considered black okay. The implementation will be tested right on a wireless sensor network using ZigBee technology. Network topology uses a mesh where each node can have more than one routing table[4]. The Enhanced Check Agent method can increase throughput to 100 percent.

This paper proposes an infrared sensor human target locating system for the Internet of Things. In this design, the wireless sensor network is designed and developed to detect human targets by using 6LoWPAN protocol and pyroelectric infrared (PIR) sensors. Based on the detection data acquired by multiple sensor nodes, K-means++ clustering algorithm combined with cost function is applied to complete human target location in a 10m×10m detection area. The experimental results indicate the human locating system works well and the user can view the location information on the terminal devices.
Wang, H., Ma, L., Bai, H..  2020.  A Three-tier Scheme for Sybil Attack Detection in Wireless Sensor Networks. 2020 5th International Conference on Computer and Communication Systems (ICCCS). :752–756.
Wireless sensor network (WSN) is a wireless self-organizing multi-hop network that can sense and collect the information of the monitored environment through a certain number of sensor nodes which deployed in a certain area and transmit the collected information to the client. Due to the limited power and data capacity stored by the micro sensor, it is weak in communication with other nodes, data storage and calculation, and is very vulnerable to attack and harm to the entire network. The Sybil attack is a classic example. Sybil attack refers to the attack in which malicious nodes forge multiple node identities to participate in network operation. Malicious attackers can forge multiple node identities to participate in data forwarding. So that the data obtained by the end user without any use value. In this paper, we propose a three-tier detection scheme for the Sybil node in the severe environment. Every sensor node will determine whether they are Sybil nodes through the first-level and second-level high-energy node detection. Finally, the base station determines whether the Sybil node detected by the first two stages is true Sybil node. The simulation results show that our proposed scheme significantly improves network lifetime, and effectively improves the accuracy of Sybil node detection.
Kaur, M., Malik, A..  2018.  An Efficient and Reliable Routing Protocol Using Bio-Inspired Techniques for Congestion Control in WSN. 2018 4th International Conference on Computing Sciences (ICCS). :15—22.

In wireless sensor networks (WSNs), congestion control is a very essential region of concern. When the packets that are coming get increased than the actual capacity of network or nodes results into congestion in the network. Congestion in network can cause reduction in throughput, increase in network delay, and increase in packet loss and sensor energy waste. For that reason, new complex methods are mandatory to tackle with congestion. So it is necessary to become aware of congestion and manage the congested resources in wireless sensor networks for enhancing the network performance. Diverse methodologies for congestion recognition and prevention have been presented in the previous couple of years. To handle some of the problems, this paper exhibits a new technique for controlling the congestion. An efficient and reliable routing protocol (ERRP) based on bio inspired algorithms is introduced in this paper for solving congestion problem. In the proposed work, a way is calculated to send the packets on the new pathway. The proposed work has used three approaches for finding the path which results into a congestion free path. Our analysis and simulation results shows that our approach provides better performance as compared to previous approaches in terms of throughput, packet loss, delay etc.

Network lifetime and energy consumption of sensor nodes have an inversely proportional relationship. Thus, it is important to ensure source location privacy (SLP) routing schemes are energy-efficient. This work performs an experimental evaluation of some existing routing schemes and proposes a new angle-based routing algorithm to modify the schemes. The dynamic route creation process of the modified schemes is characterized by processes which include determination of route and banned regions and computation of control angle and lead factor parameters. Results of the analysis show that the modified schemes are effective at obfuscating the adversaries to provide strong SLP protection. Furthermore, the modified schemes consume relatively lower energy and guarantee longer network lifetime.

In this paper, we investigate the protection mechanism of source location privacy, in which back-tracing attack is performed by an adversary. A dynamic and disjoint routing mechanism (DDRM) is proposed to achieve a strong protection for source location privacy in an energy-efficient manner. Specially, the selection of intermediate node renders the message transmission randomly and flexibly. By constructing k disjoint paths, an adversary could not receive sufficient messages to locate the source node. Simulation results illustrate the effectiveness of the proposed mechanism.

There exist numerous strategies for Source Location Privacy (SLP) routing schemes. In this study, an experimental analysis of a few routing schemes is done to investigate the influence of the routing scheme algorithms on the privacy protection level and the network lifetime performance. The analysis involved four categories of SLP routing schemes. Analysis results revealed that the algorithms used in the representative schemes for tree-based and angle-based routing schemes incur the highest influence. The tree-based algorithm stimulates the highest energy consumption with the lowest network lifetime while the angle-based algorithm does the opposite. Moreover, for the tree-based algorithm, the influence is highly dependent on the region of the network domain.

Due to their low complexity and robustness in nature, wireless sensor networks are a key component in cyber-physical system. The integration of wireless sensor network in cyber-physical system provides immense benefits in distributed controlled environment. However, the open nature of the wireless medium makes resource-constrained WSN vulnerable to unauthorized interception and detection. Privacy is becoming one of the major issues that jeopardize the successful deployment of WSN. In this paper, we propose a scheme named HASHA to provide location privacy. Different from previous approaches, HASHA protect nodes' location privacy at data link layer. It is well known that payload at data link layer frame is well protected through cryptosystem, but addresses at data link layer leaves unprotected. The adversaries can identify nodes in the network easily by capturing frames and check the source and destination addresses. If both addresses are well protected and unknown to the adversaries, they cannot identify nodes of the targeted networks, rendering it very difficult to launch traffic analysis and locate subjects. Simulation and analytical results demonstrate that our scheme provides stronger privacy protection and requires much less energy.

An exciting network called smart IoT has great potential to improve the level of our daily activities and the communication. Source location privacy is one of the critical problems in the wireless sensor network (WSN). Privacy protections, especially source location protection, prevent sensor nodes from revealing valuable information about targets. In this paper, we first discuss about the current security architecture and attack modes. Then we propose a scheme based on cloud for protecting source location, which is named CPSLP. This proposed CPSLP scheme transforms the location of the hotspot to cause an obvious traffic inconsistency. We adopt multiple sinks to change the destination of packet randomly in each transmission. The intermediate node makes routing path more varied. The simulation results demonstrate that our scheme can confuse the detection of adversary and reduce the capture probability.
Mutalemwa, Lilian C., Shin, Seokjoo.  2018.  Realizing Source Location Privacy in Wireless Sensor Networks Through Agent Node Routing. 2018 International Conference on Information and Communication Technology Convergence (ICTC). :1283–1285.
Wireless Sensor Networks (WSNs) are used in sensitive applications such as in asset monitoring applications. Due to the sensitivity of information in these applications, it is important to ensure that flow of data between sensor nodes is secure and does not expose any information about the source node or the monitored assets. This paper proposes a scheme to preserve the source location privacy based on random routing techniques. To achieve high privacy, the proposed scheme randomly sends packet to sink node through tactically positioned agent nodes. The position of agent nodes is designed to guarantee that successive packets are routed through highly random and perplexing routing paths as compared to other routing schemes. Simulation results demonstrate that proposed scheme provides longer safety period and higher privacy against both, patient and cautious adversaries.

In recent trends, Cyber-Physical Systems (CPS) and Internet of Things interpret an evolution of computerized integration connectivity. The specific research challenges in CPS as security, privacy, data analytics, participate sensing, smart decision making. In addition, The challenges in Wireless Sensor Network (WSN) includes secure architecture, energy efficient protocols and quality of services. In this paper, we present an architectures of CPS and its protocols and applications. We propose software related mobile sensing paradigm namely Mobile Sensor Information Agent (MSIA). It works as plug-in based for CPS middleware and scalable applications in mobile devices. The working principle MSIA is acts intermediary device and gathers data from a various external sensors and its upload to cloud on demand. CPS needs tight integration between cyber world and man-made physical world to achieve stability, security, reliability, robustness, and efficiency in the system. Emerging software-defined networking (SDN) can be integrated as the communication infrastructure with CPS infrastructure to accomplish such system. Thus we propose a possible SDN-based CPS framework to improve the performance of the system.

Internet of things era grown very rapidly in Industrial Revolution 4.0, there are many researchers use the Wireless Sensor Network (WSN) technology to obtain the data for environmental monitoring. The data obtained from WSN will be sent to the Data Center, where users can view and collect all of data from the Data Center using end devices such as personal computer, laptop, and mobile phone. The Data Center would be very dangerous, because everyone can intercept, track and even modify the data. Security requirement to ensure the confidentiality all of stored data in the data center and give the authenticity in data has not changed during the collection process. Ciphertext Policy Attribute-Based Encryption (CP-ABE) can become a solution to secure the confidentiality for all of data. Only users with appropriate rule of policy can get the original data. To guarantee there is no changes during the collection process of the data then require the time stamp digital signature for securing the data integrity. To protect the confidentiality and data integrity, we propose a security mechanism using CP-ABE with user revocation and Time Stamp Digital Signature using Elliptic Curve Cryptography (ECC) 384 bits. Our system can do the revocation for the users who did the illegal access. Our system is not only securing the data but also providing the guarantee that is no changes during the collection process of the data from the Data Center.
