In recent years, a vast research has been seen going on in the field of Mobile Ad Hoc Networks (MANETs). In MANET each node is wirelessly interconnect with the other node through different network topologies and there are various protocols which help nodes to interconnect with the neighbors nodes and hence make wireless network. In a mobile ad hoc network, nodes move arbitrarily; therefore the network may experience rapid and unpredictable topology changes. Because nodes in a MANET normally have limited transmission ranges, some nodes cannot communicate directly with each other. Hence, routing paths in mobile ad hoc networks potentially contain multiple hops, and every node in mobile ad hoc networks has the responsibility to act as a router. In this paper we provide an overview of a wide range of the existing routing protocols with a particular focus on their characteristics and functionality. We also have discussed the literature survey of various Proactive, Reactive and Hybrid Protocols such, as AODV, DSDV, DSR, etc. in details. Furthermore, the Comparison of Proactive, Reactive and Hybrid protocols have also been discussed on the basis of some parameters, Advantages and Disadvantages.
