A Study on Dynamic Source Routing In Ad Hoc Wireless Networks

The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multihop wireless ad hoc networks of mobile nodes. DSR allows the network to be completely self-organizing and selfconfiguring, without the need for any existing network infrastructure or administration. The protocol is composed of the two main mechanisms of ìRoute Discoveryî and ìRoute Maintenanceî, which work together to allow nodes to discover and maintain routes to arbitrary destinations in the ad hoc network. All aspects of the protocol operate entirely on-demand, allowing the routing packet overhead of DSR to scale automatically to only that needed to react to changes in the routes currently in use. The protocol allows multiple routes to any destination and allows each sender to select and control the routes used in routing its packets, for example for use in load balancing or for increased robustness.
