MANET is an infrastructure less network which consists of mobile nodes without central administration. It's routing algorithm should not only be capable of finding the shortest path between the source and destination, but it should also be adaptive, in terms of the changing state of the nodes, the changing load conditions of the network and also the changing state of the environment. In this paper, a performance comparison of three popular mobile ad-hoc network routing protocols i.e. Dynamic Source Routing (DSR), Optimization Link State Routing (OLSR) and Zone Routing Protocol (ZRP) is presented with variable pause time and packet transmission rate.
