MPG-TAR: Mobile Process Groups Based Trust Aware Routing Protocol for MANETs

Routing in mobile ad-hoc networks is a challenging task. This paper proposes MPG-TAR, trust-aware routing protocol based on the formation of trusted Mobile Process groups(MPG). MPG is a collection of processes or mobile nodes present in defined vicinity where they all lie within each other’s radio transmission range. The trusted MPG groups formed in MPGTAR calculate trust based on the mobility rate, membership time within a local group and the number of overlapping groups of a node. The proposed protocol continuously computes and updates the reliability, trustworthiness of a node and finds the confidence level in that node. If the node is trustworthy and reliable, the confidence in that node will be increased to trust the node for forwarding a data packet. Simulation of MPG-TAR was done using Glomosim simulator.
