Survey of Routing Protocol in MANET

Abstract

This survey investigates routing protocols for mobile ad hoc networks (MANETs). MANET is a collection of movable nodes which can move anywhere in Network. As nodes are mobile it can dynamically change their topology at any time. Broadcasting is a fundamental operation in Mobile Ad Hoc Network MANETs whereby a source node sends the identical or same packet to all the nodes in the network. Simple flooding technique used for route discovery where a mobile node blindly rebroadcast received route request packet until a route established for particular destination. While broadcasting has many advantages, it also have some disadvantage such as the broadcast storm problem, it cause redundant retransmission, collision, and contention in network. This paper discusses the various routing protocol to overcome this problem, also reduce the routing overhead to improve performance
