摘要：
In this letter, we study the secure transmission in multihop wireless networks with randomize-and-forward relaying, in the presence of randomly distributed eavesdroppers. By considering adaptive encoder with ON-OFF transmission scheme, we investigate the optimal design of the wiretap code and routing strategies to maximize the secrecy rate while satisfying the secrecy outage probability constraint. We derive the exact expressions for the optimal rate parameters of the wiretap code. Then, the secure routing problem is solved by revising the classical Bellman-Ford algorithm. Simulation results are conducted to verify our analysis.
