Extended DSR for MANET: Preemptive Switching over Multiple Routes to Reduce Route Discovery Overhead

K.Sangeetha Supriya


A mobile ad-hoc network (MANET) is a self configuring network of mobile routers (and associated hosts) connected by wireless links, the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily; thus, the network’s wireless topology changes rapidly and unpredictably. The Dynamic Source Routing (DSR) protocol is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. It is based on the concept of source routing, a routing technique in which the sender of the packet determines the complete sequence of the nodes through which to forward the packet. The sender explicitly lists this route in the packet’s header, identifying each forwarding “hop” by the address of the next node to which to transmit the packet on its way to the destination host. The objective of this paper is Extension of DSR in such a way to provide the best path for communication between nodes in a wireless network within a highly dynamic network. The main purpose is to reduce the time delay for the discovery of the communication path. It is achieved by switching through the alternative path’s for nodal communication when breakage occurs. Extended DSR for MANET: Preemptive Switching over Multiple Routes to Reduce Route Discovery OverheadMrs
