A Survey: On Unicast Routing Protocols for Mobile Ad Hoc Network

A Mobile Ad-hoc Network (MANET) is form over wireless media by the various mobile nodes. In other word we can say if various mobile nodes from a network without any infrastructure, such kind of network is known as Mobile Ad-hoc Network. In MANET communication between two mobile devices are performed by routing protocol. In MANET each mobile node can directly communicate with other mobile node if both mobile nodes are within transmission range. Otherwise the nodes present in between have to forward the packets for them on network. In such condition each mobile node acts as a router to forward the packets for others. Forwarding packet in MANET with limited resources (like bandwidth constraints, hidden terminal and limited battery power) is a very challenging task. Till data may routing protocols were proposed are an improvement over a number of different strategies considered in the literature for a given network. So it is quite difficult to find out which protocol may perform better under different network conditions of MANET. In this survey paper we proved an overview of various routing protocols proposed by various researchers. We will also provide comparative study of all routing protocol to find out the performance of protocol for large MANET.
