Routing Strategies in Adhoc Network

Wireless Communication is the transfer of information over long distances without the use of wires. The connectivity of wireless communication is nearly everywhere and becoming highly affordable even for people who are in the pyramid’s bottom. Wireless networking is slowly pushing out wired networking and ideal solution for a user that wants the ability and freedom to roam without having a fixed cable determining the distance that user can go before having to stop due to a cable. ? “connect anytime, anywhere, anyhow” promising ubiquitous network access at high speed to the end users, has been a topic of great interest especially for the wireless telecom industry. An ad hoc network has certain characteristics, which imposes new demand on routing protocols. The most important characteristics is the dynamic topology, which is the consequence of node mobility. Nodes can change position quite frequently, which means that we need a routing protocol that quickly adapts to topology changes. This means that routing protocol should try to minimize control traffic, such as periodic update messages, instead the routing protocols should be reactive, thus only calculate routes upon receiving a specific request.
