A Novel Trust Based Routing Protocol to prevent the Malicious Nodes in Wireless Sensor Networks

In Wireless Sensor Networks, topology management guarantees energy efficiency and maintains the connection among the nodes.Most of the existing systems are not providing trust among the sensor nodes.Therefore,issues in security should also be considered in the management of topology in WSN.To overcome the above problem,in this paper,we propose (TBR) a TRust Based Routing with Topology management.Moreover this Topology Management uses RSSI values for constructing Topology in WSN and for maintaining the nodes in transmission range in the presence of malicious nodes.This model is used to perform secure routing in WSN. From the experiment conducted it is observed that the proposed method provides an efficient trust based routing in WSN compared to existing methods.
