Abstract—In this paper a Secure Routing Protocol for large Wireless Sensor Networks has been proposed. The protocol can take care of the mobility in the sensor nodes as well as in the base station. The entire sensor field is divided into some logical clusters and each cluster contains three different kinds of nodes namely Gateway Node, Cluster Head Node and Ordinary Sensor Node. The communication from the sensor nodes towards the base station happens in hierarchical manner and also in multi-hop fashion. Different secret keys are used for secure communication and the use of secret keys makes the communications secure. The performance of the proposed protocol in terms of throughput and average energy consumption for communication has been compared with that of LEACH-mobile. Security strengths of the protocol are also analyzed.
Index Terms—Wireless sensor networks, secure routing,hierarchical routing, security threats.
