In order to reduce the communication cost and time the authors are looking forward for successful implementation of an infrastructure less network like Mobile Ad Hoc Network in all arena of wireless mobile communication. But still it is a challenge to decide a most appropriate routing protocol for MANET. In MANET there is no fixed topology due to the mobility of nodes, interference, multi-path propagation and path loss. Since MANET does not use fixed infrastructure rather it always have to find suitable router and routing path for each communication, existing established routing protocol is not suitable for MANET to function properly. Different Routing protocols have been proposed to meet the challenges with MANETs.
