An ad hoc wireless network consists of a set of hosts (mobile nodes) which are connected together by wireless links. The nodes can communicate with each other using different routing protocols. The routing protocols perform well when the nodes are stationary but degrade drastically when the nodes are mobile. A variety of routing protocols have been proposed for ad hoc networks in the past. Based on update mechanisms, they are classified into reactive, proactive and hybrid routing protocols. The performance of these protocols varies depending on the simulation environment.
