Abstract:
Mobile ad hoc networks are characterized by multi- hop wireless links, absence of any cellular infrastructure, and frequent host mobility. Design of efficient routing protocols in such networks is a challenging issue”. A class of routing protocols called on-demand protocols have recently attained more attention as compared to proactive routing protocols because of their low routing overhead due to their abilities and efficiency. The on- demand protocols depend on query floods to discover routes whenever a new route is needed. Such floods take up a substantial portion of network bandwidth. This paper focuses on a particular on demand protocol, called Dynamic Source Routing, and shows how intelligent use of multipath techniques can reduce the frequency of query floods. By incorporating the multipath routing approach into DSR protocol and modifying the control messages and data structures of DSR protocol, the routing over-head and normalized routing load is reduced through the route discovery process. The simulation result shows that the developed protocol RMDSR outperforms DSR protocol in terms of routing overhead and normalized routing load.
