A Swarm Intelligent Secured Routing for Wireless Sensor Network

Rapid development of sensor technology, within short span has attracted extensive attention in wide range of applications. But the adhoc nature of the Wireless Sensor Network (WSN) does not support any traditional routing or security scheme and hence the problem of finding a minimum cost, secured and reliable path between the source and destination still becomes a crisis. Therefore, a route maintenance algorithm for WSN should tolerate any intermittent failures and reach destination through shortest and minimal latency path. This thrust has motivated to design the proposed algorithm that provides a probabilistic multi-path routing which constantly updates the goodness of choosing a particular path by measuring the link quality in those paths and also prioritizes the forwarding candidates based on its truthfulness in addition to the shortest path metric. Moreover this proposed system also concentrates on security of a node by assessing its truthfulness. The Prejudice value (propensity to trust/mistrust its neighbors) and deserve value (information of other nodes about this node) are computed to detect the trustworthiness of the node. The effect of packet delivery was analyzed and it is found that perfection is brought about by the participation of the forwarding candidates.
