Channel coding and interleaver for secure wireless sensor networks

In wireless sensor networks, security and energy efficiency are two important topics. In multipath routing, threat can come from compromised nodes, which might relay incorrect information (packet) to the next node during routing. Detection of such incorrect information is very difficult. In this paper, we propose a secure and energy efficient multipath-routing (SEEM) scheme aided with channel coding and interleaver. The M-path in multipath routing are selected using existing routing algorithm and fuzzy logic system considering the average remaining battery capacity and mobility of associated nodes. Simulation results show that even if certain paths are compromised, the receiver node is still able to recover the transmitted message from errors with very low bit error rate
