Simulation of routing protocol on ad hoc networks using OPNET software

An ad hoc network is an instantly deployable wireless network that does not require the services of any networking infrastructure such as base stations or routers. The key feature of these networks is their ease of deployment that makes it ideally suitable for battlefield, search and rescue and disaster relief operations. These networks can operate on a single­hop or multi-hop basis where nodes in the network are able to act as intermediaries (routers) for communications of other nodes. Routing in ad hoc networks is nontrivial due to highly dynamic environment. In recent years several routing protocols targeted at mobile ad hoc networks are being proposed and prominent among them are DSDV, AODV, TORA, and DSR.
