POWER AWARE ROUTING FOR MOBILE AGENT IN AD-HOC NETWORKS
Siddapuram Arvind, Thondepu Adilakshmi, Guru Nānak · 2009
Wireless networks allow a more flexible model of communication than traditional networks since the user is not limited to a fixed physical location. Unlike cellular wireless networks, an ad hoc wireless network does not have any fixed communication infrastructure. For an active connection, the end host as well as the intermediate nodes can be mobile. Therefore routes are subject to frequent disconnections. In such an environment, it is important to minimize disruptions caused by the changing topology for critical application such as voice and video. This presents a difficult challenge for routing protocols, since rapid reconstruction of routes is crucial in the presence of topology changes. By exploiting non-random behaviors for the mobility patterns that mobile users exhibit, we can predict the future state of network topology and perform route reconstruction proactively in a timely manner. Moreover, by using the predicted information on the network topology, we can eliminate transmissions of control packets and thus reduce overhead. This paper proposes a methodology of routing protocol for misbehaving network called RMP-ANT (Route Management Protocol for Ad Hoc Network) with a power management scheme called as MARI (Routing Intelligent Mobile Agent) protocol, and discusses about the various schemes to improve routing protocol performance by using mobility prediction. The protocol used here enables nodes to detect misbehavior by observing the status of the nodes. The paper also proposes distributed reputation system that can cope with false information and effective utilization of the power.
