A Novel Cluster Based Survivable Routing Protocol for Wireless Sensor Network

Abstract

Sensor nodes easily suffer from failure, attack or capture because of the limited energy, storage, communication ability, complex and severe network environment when WSN is applied to emergency or battlefield environment. Thus, the basic scout mission is influenced. In this paper, a survivability route protocol named SRPC in cluster-based WSN is put forward. The protocol uses key negotiation and identity authentication mechanism to resist the attacks of malicious nodes; when the main cluster head is destroyed, monitoring data will be transmitted to the base station by the backup cluster head chain. The simulation results show that, SRPC protocol can not only resist the attacks of the enemy malicious nodes based on energy balance, but also assure reliable delivery of the packets after the cluster head is attacked or destroyed. As a result, the survivable ability of WSN in battlefield is improved.
