User's deception mechanisms against jammers in wireless energy harvesting networks

Abstract

In wireless energy harvesting communication networks, a user harvests energy from an environment and uses the energy for data transmission. However, the user's data transmission is susceptible to a jamming attack by jammers, which also harvest energy from the environment. To address this problem, therefore we introduce a user's deception mechanism in which the user can transmit fake signals (i.e., blank transmission) to trigger the jammers to perform the attack, wasting their energy. We propose an analysis of the network with the deception mechanism based on a Markov chain. The performance evaluation reveals some interesting results. For example, the user can adjust the number of blank transmissions to achieve the highest throughput. We provide a benchmarking scheme based on an optimization. The benchmarking is useful for developing an effective deception mechanism with minimum complexity and knowledge about the network and jammers. © 2015 IEEE.
