Performance analysis of multipath routing based on source routing

Abstract

Mobile AdHoc Networks (MANETs) is a collection of mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration, and they interact with each other over wireless links. Due to the dynamic topology, developing better routing protocol became a challenging tasks. Multi-path routing protocol is one of the approaches used to have less overhead, better bandwidth cost by distributing the load among a set of paths. Nowadays, different types of protocols exist. Nevertheless, the source routing ones, based on information known at the source of the communication, seem to attract more studies. Source routing protocols had shown interesting results in realistic scenarios in areas such as military battlefields or airport stations. Our study deals with one of those protocol: DSR. We decided to go further and therefore we designed a new multipath algorithm. A set of path selection criteria have been used to improve the end to end delay. The simulation experiments are conducted using OMNeT++ 4.0 .We will compare the performance of the suggested algorithm to the performance of the conventional Dynamic Source Routing Protocol (DSR).
