An Efficient Energy based Detection of Malicious Node in Mobile Wireless Sensor Networks

Mobile wireless sensor networks (MWSN) are composed of a large number of wireless sensors and they require a careful consumption of available energy to prolong the life of the network. From the security point of view, existing detection schemes consumes node energy and thus reduces the life time of the network. This paper focuses on energy based scheme for detecting the malicious node in the forward routing path. This detection scheme suits any standard routing protocol. The forward route selection path is identified by using dynamic source routing protocol. The proposed scheme is simulated in glomosim and evaluated using packet throughput, percentage of byte overheads, energy consumption, and the accuracy of detection. The network with moderate mobility is used and the proposed scheme consumes 20 % of node energy.
