Abstract

Ad-hoc wireless networks are selforganising, infrastructure less networks characterized by dynamic topology, limited channel bandwidth and limited battery power at the nodes. The nodes communicate with each other through radio links in multihop specified routing protocols. The concept of agent is introduced in MANET to reduce the load on node .The routing performance in Mobile Ad-hoc Networks (MANETs) relies on the cooperation of the individual nodes that constitute the network. The existence of misbehaving nodes may paralyze the routing operation in MANET. To overcome this behavior, the trustworthiness of the network nodes should be considered in the route selection process combined with the hop count. The trustworthiness is achieved by measuring the trust value for each node in the network. In this paper we have considered trusted agent based routing mechanism in two reactive protocols and presented the analysis of trusted agent in the extensions of Adhoc on Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) routing protocols in MANET.
