Abstract

Wireless Networking is an emerging technology that allows users to access information and services anywhere, regardless of their geographic areas over the past few years with the trend of mobile computing. Mobile Adhoc Network (MANET) has become one of the most important wireless communication mechanisms among all, unlike traditional network. MANET represents complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize temporarily. MANET is an autonomously self-organized networks without infrastructure support. In MANET, nodes can 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. Routing in MANET potentially contains multiple hops, and every node in mobile ad hoc networks has the responsibility to act as a router. In MANET, network topology can dynamically be changed in an unpredictable manner since the nodes are free to move. Every single node in the MANET works as both receiver and transmitter. Each node directly communicates with others, when they are both within their communication ranges. All nodes work as routers and take path in discovery and maintenance of routes to other nodes in the network. In this paper, a review on the routing protocols for mobile adhoc networks, challenges, issues, and applications were presented. The objective of this study is the comparative analysis of various routing protocols for MANET in different manner.
