Trust Aware Resilient Geographic Routing in Wireless Ad Hoc and Sensor Networks

The objective of the paper is to propose trust aware routing method for cooperative and resilient geographic routing in Wireless Ad-hoc and Sensor Networks (WASNs). The proposed method calculates the trust value on the basis of node behavior in routing the packets. The proposed method is designed to have the features such as self-adaptability, low overhead, and dependability which are missing in the existing trust models. With the trust values, the proposed method detects and isolates the malicious nodes dynamically during the routing process. The simulation results obtained using the network simulator ns-2 shows the efficiency of the proposed trust model.
