In order to make a thorough evaluation of the security against eavesdropping in heterogeneous radio access network (RAN) with relays, this paper proposes a novel secrecy graph-based secrecy evaluation scheme for distributed wireless relay networks with eavesdropping present. Our scheme firstly models user and eavesdropper with the nonuniform distributions in a discrete system and decides the best path choice of users and relays for the purpose of security. Secondly, we derive the average eavesdropping effect (AEE) based on the known distribution and arrangement of uplink path, and investigate the derived results and the different relay deployment plans. Taking into account various factors (fluctuation of user traffic, burden limitation of relay etc), we efficiently utilize the available resources to simulate the real scenarios to implement the accurate secrecy evaluations. Finally, the simulation results prove that our proposed scheme outperform the other existing ones. © 2013 IEEE.
