A Secure Routing Algorithm for Hierarchical Cluster-tree WSN Based on Energy Aware Mechanism

Abstract

Routing algorithm based on hierarchical cluster-tree topology is comparatively ordinary and easy to expand, yet it lacks consideration in best energy consuming structure in WSN network and the route security problems. This paper exploits energy aware mechanism to make sensible choices of relay node in communication rout, decreasing the hops of data transmitting, saving the energy and prolonging the life time of WSN. On basis of the algorithm, the security problem of net data leakage and missing caused by hostile intrusion is improved with cryptography and authentication. Simulation results show that the algorithm owns advantage over traditional ones based on hierarchical cluster tree topology on aspects of survivability, transmit hopss and network robustness.
