On Performance Analysis of Protective Jamming Schemes in Wireless Sensor Networks

Abstract

Wireless sensor networks (WSNs) play an important role in Cyber Physical Social Sensing (CPSS) systems. An eavesdropping attack is one of the most serious threats to WSNs since it is a prerequisite for other malicious attacks. In this paper, we propose a novel anti-eavesdropping mechanism by introducing friendly jammers to wireless sensor networks (WSNs). In particular, we establish a theoretical framework to evaluate the eavesdropping risk of WSNs with friendly jammers and that of WSNs without jammers. Our theoretical model takes into account various channel conditions such as the path loss and Rayleigh fading, the placement schemes of jammers and the power controlling schemes of jammers. Extensive results show that using jammers in WSNs can effectively reduce the eavesdropping risk. Besides, our results also show that the appropriate placement of jammers and the proper assignment of emitting power of jammers can not only mitigate the eavesdropping risk but also may have no significant impairment to the legitimate communications.

A Novel Friendly Jamming Scheme in Industrial Crowdsensing Networks against Eavesdropping Attack

“…It is feasible in a practical industrial environment that the eavesdropper has the difficulty of entering the protected network area (e.g., the barbed wire entanglement around a plant). However, we can also apply our previous results in [ 27 ] to analyze the scenario in which an eavesdropper enters the network area. In particular, we consider that friendly jammers are regularly placed at deterministic locations [ 27 ] and the eavesdropper is located at the center of this area, as shown in Figure 9 .…”

“…However, cryptosystems can only help hiding the meaning of information during transmissions, but not the existence of the information itself. In addition, even though cryptosystems increase the difficulty of understanding the true meaning of information for eavesdroppers, it is still possible for the eavesdroppers to access all the information as indicated in [24]. The reason may owe to the lightweight cryptosystems that have only been used in IIoT because of in sufficient computing capability IIoT devices.…”

A Methodology for the Design of Application-Specific Cyber-Physical Social Sensing Co-Simulators

“…During the last months CPSS has become a very popular research topic. Different works about the applications of the CPSS paradigm to social Big Data [ 32 ], robotics [ 26 ], people tracking [ 27 ] and wireless sensor networks (WSN) [ 33 ] have been recently reported. In most of these papers, experimental validations are based on laboratory deployments, theoretical analyses or concept proofs [ 24 ].…”
