Security‐oriented cooperation scheme in wireless cooperative networks
Li Wang, Lie‐Liang Yang, Jacob Xin, Mei Na Song · IET Communications · 2014
This study proposes a security‐oriented cooperation (SOC) scheme, which first determines one of the three possible cooperation scenarios, namely the jammer only, relay only and the relay–jammer pair, according to the security requirement and network's operational conditions. After determining a cooperation scenario, then, the selection of a relay or/and a jammer as well as their transmit power are jointly optimised with the objective to attain a good trade‐off between security performance and energy consumption. The performance of the networks employing the proposed SOC is investigated here over finite‐state Markov channels. The studies and results explain that the proposed SOC scheme constitutes one of the promising SOC schemes. It belongs to a generalised cooperative security scheme, which adapts according to the specific security requirement and communication environments.
