摘要：Reducing node energy consumption and improving network security are two major goals in designingrouting protocols. In this paper, a security enhanced routing protocol based on multi-hop communication ofcluster head is designed. The proposed protocol is based on the LEACH protocol, layering the network intoclusters, and evaluating the cluster head and the nodes of the cluster to enhance security. Multi-hopcommunication between cluster heads reduces the energy consumption of the cluster head node due tocommunication with the base station and improves the security on the routing path by using a trafficfeedback detection mechanism. The simulation results show that the proposed protocol can balance theenergy consumption of communication between cluster heads, extend the lifetime of wireless sensornetworks and improve the security of the network.
