IMPLEMENTATION OF DYNAMIC SOURCE ROUTING (DSR) IN MOBILE AD HOC NETWORK (MANET)

Abstract

Generally, the Base station (BS) is fixed in the mobile communication system however in Mobile Ad hoc network, Base Station (BS)s is not used, thus it is named as infrastructure less network which can manage its network independently. The Routing protocol plays an important role and a lot of research has been done in this area. This paper presents a protocol for routing mobile ad hoc network (MANET) that uses dynamic source routing. This protocol adapts quickly to the change in the routing path as the host is changing its location frequently. DSR allows the network to be fully self-organising and self-configuring without the need for any existing network. The protocol is composed of the two mechanisms of route discovery and route maintenance work together to search for the shortest path and also to maintain source route to arbitrary destination in the Mobile ad hoc network, we used optimize routing protocol in Mobile ad hoc network (MANET).This optimization is done on DSR (Dynamic Source Routing) protocol using ANT algorithm. The performance of DSR is analyzed using Qualnet 5.2 with respect to QOS (Quality of Service) of throughput, end to end delay, Routing overhead, Average hop count. All the parameter are analyzed in three different scenario of velocity, pause time and traffic connection. All the result are compared with the result of standard DSR routing protocol. The comparison shows that the DSR-ant has better performance than standard DSR. By using Ant algorithm, the DSR optimization can be improved with a smaller delay and the number of hop to transfer information between nodes.
