摘要：
In this paper, we investigate the secured transmission in cluster-based multi-hop networks. In particular, we evaluate the secrecy performance of three various protocols over Rayleigh fading channel. In the first protocol, at each cluster, a relay is randomly selected to forward the source message to the next cluster. In the second and third ones, relay selection methods are applied to enhance secrecy performance. We derive closed-form expressions of secrecy outage probability and capacity, and then perform Monte Carlo simulations to verify the derivations.
