A mobility factor based path selection scheme for Mobile Ad-hoc Networks

Abstract

In this paper, we propose a mobility factor based path selection scheme in Mobile Ad-hoc Network (MANET). In MANET, Nodal mobility is one of the important issues to determine the potential capacity of ad hoc networks. Various mobility metrics have been proposed in the literature as measurement of topological changes in networks. All such metrics describe the link or path stability to allow adaptive routing in MANET based on predicted link behaviour. We investigate and find that a path can become reliable and the average throughput of the network can increase if we select a route considering the mobility of the network nodes. Our proposed scheme selects the nodes to construct a path based on their mobility. In our work a trust value is generated by a trust module that calculates and compares mobility of the concerned nodes. Simulation results show that our proposed scheme performs better than pure Ad hoc On-Demand Distance Vector (AODV) and Dynamic Source Routing (DSR) protocols.
