A SURVEY PAPER ON DYNAMIC SOURCE ROUTING PROTOCOL (DSR) IN AD-HOC NETWORK

Dynamic source routing protocol (DSR) is an on demand routing protocol suited for ad-hoc network. An ad hoc network is a network that is composed of individual devices communicating with each other directly. And another word to say an ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration.[10] Many ad hoc networks are local area networks where computers or other devices are enabled to send data directly to one another rather than going through a centralized access point. In this research we use optimized routing protocols in mobile ad hoc network (MANET), the optimization is done on the routing protocol DSR (Dynamic Source Routing) which is reactive routing protocol using ant algorithm. Then we analysis and evaluated the performance of this routing protocol in various scenario and compared the result with standard DSR routing protocol. The results of this research indicate the performance of DSR-ant has a better performance In such an environment, it may be necessary for one mobile host to enlist the aid of other hosts in forwarding a packet to its destination, due to the limited range of each mobile host's wireless transmissions. This paper presents a protocol for routing in ad hoc networks that uses dynamic source routing. The protocol adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently. Based on results from a packet-level simulation of mobile hosts operating in an ad hoc network, the protocol performs well over a variety of environmental conditions such as host density and movement rates. For all but the highest rates of host movement simulated, the overhead of the protocol is quite low, falling to just 1% of total data packets transmitted for moderate movement rates in a network of 24 mobile hosts.
