Abstract
- In this paper, we evaluate secrecy performance of cooperative jamming (CJ) aided secure transmission for Multi-hop Low-Energy Adaptive Clustering Hierarchy (M-LEACH) networks, where data transmission between a source and a destination is performed via cluster heads (CHs) of intermediate clusters, and is overheard by an eavesdropper. To protect the source information at each hop, each CH selects one or many cluster nodes to realize the CJ technique. We propose energy harvesting (EH) based jammer selection methods named MAX-EH, MAX-IP and ALL-CJ, where the selected jammer(s) has to harvest wireless energy from a dedicated power beacon to generate jamming noises. In MAX-EH, the cluster node obtained the MAXimum Energy Harvested from the power beacon is chosen. In MAX-IP, the selected jammer is the cluster node providing the MAXimum Interference Power to the eavesdropper. In ALL-CJ, ALL cluster nodes in the clusters take part in the CJ operation. For performance evaluation, we derive expressions of the end-to-end (e2e) secrecy outage probability (SOP) for the proposed methods over Rayleigh fading channels. We then perform Monte-Carlo based computer simulations to verify the theoretical results. The results presented that the proposed methods outperform the RANDom jammer selection (RAND) and the corresponding method WithOut using the CJ technique (WO-CJ).
