Cornbach Alpha Coefficient based Trust Model for Routing in MANET

S. Pariselvam, Dr. R.M.S. Parvathi


Co-operation is considered as one of the important factor that has a vital influence in the reliable data dissemination of packets between the wireless nodes present in an ad hoc scenario. This co-operation is also essential for maintaining both the forward and reverse routes between the source and the sink nodes. Due to the stringent availability of resources in MANETs, Some of the participating nodes present in the ad hoc environment may exhibit a malicious behavior of intentionally dropping the data packets rather than forwarding to their neighbor nodes. This maliciousness of the nodes may result in the degradation in the network performance. In this paper. We formulate and propose a Cornbach alpha coefficient based trust model, which manipulates the trust of each and every node present in the topology based on Cornbach alpha coefficient. The experimental analysis of the proposed trust model is studied through the ns-2 simulation with the aid of evaluation parameters namely packet delivery ratio, control overhead, total overhead and throughput by varying the number of malicious nodes. This proposed scheme performs well when compared to the model present in the literature like split half reliability model.
