Routing in Wireless Sensor Network using Fuzzy based Trust Model

Wireless sensor network is a collection of large number of sensor nodes that are deployed in large number to monitor the environment. There is a great technological advancement in wireless sensor network during last few years. Due to low-cost, small-size, nature of Wireless Sensor Networks (WSNs), it allows them to sense the information in various hostile environments (e.g. military surveillance, battlefield). So, to fully achieve the capacity of WSNs, sensor nodes need to cooperate in the collection and must disseminate topology information. These sensor nodes specifically operate in a multihop routing. Sensor network in muiltihop routing faces a variety of risks which is also due to the harsh operating environments. In this paper a fuzzy based approach is introduced which will enhance the routing security and reliability in WSNs.
