Abstract

Mobile Ad-Hoc Networks (MANETs) are characterized by multi-hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. Routing must maintain required paths in such an environment with an acceptable overhead. On-Demand routing protocols discover paths only when they are requested by flooding the request through the network at great cost. Caches are used to reduce the frequency of flooding route requests. Many routing protocols exist for MANETs. On-demand routing protocols have attracted more attention because of their less overhead and wide applicability. This study is on the behavior of DSR protocol, which is based entirely on on-demand behavior. Multipath routing is gaining importance as it increases reliability and aids in load balancing. More traffic than that can be handled by the IFQ of a node reduces throughput and increases routing overhead . In this work an effort is made to integrate the benefits of multipath routing and traffic sensitive routing. Simulation studies show enhanced throughput for Traffic Sensitive Dynamic Source Routing (TSDSR) when compared to DSR.
