Abstract

A Mobile Ad-Hoc Network MANET consists of wireless hosts which may move often. The movement of hosts results in frequent changes in paths. In these cases, finding a path from source to destination becomes difficult. The well-known Ad-hoc On-Demand Distance Vector Routing AODV and Dynamic Source Routing DSR are routing protocols which are in vogue to determine a route when no route exists or a route breaks. As such to establish a new path from source to destination, it broadcasts control packets route request packets, which increase the network bandwidth consumption. As MANETs have limited bandwidth, it is essential to reduce the control packets. We propose mathematical models which use the concept of rough set and Weighted Rough Set WRS to minimise the route request packets in the existing AODV and DSR routing protocols. Rough set theory is a mathematical tool to deal with vagueness, uncertainty; and WRS theory is an extension to rough set theory which also considers the importance of the objects.
