Reactive, Proactive MANET Routing Protocol Comparison
K. Ramesh Reddy · 2012
Abstract-- Ad-hoc networking is a concept of computer communications is that the users wanting to communicate with each other form a temporary network, without any form of centralized administration. The purpose of a routing protocol is each node participating in the network acts both as host and a router and must be--- to forward packets for other nodes. An ad-hoc network has certain characteristics which imposes new demands on the routing protocol. The most important characteristic is the dynamic topology, which is a consequence of node mobility. Nodes can change position quite frequently, which means that we need a routing protocol that quickly adapts to topology changes. The nodes in an ad-hoc network can consist of laptops and personal digital assistants and are often very limited in resources such as cpu capacity. Storage capacity, battery power and bandwidth. With this protocol should try to minimize control traffic, such as periodic update messages. Instead of routing protocol only reactive can be calculate routes based on specific request. Here we have two protocols like reactive and proactive. In this paper we can try to compare the protocols, then we can identify which is perform well when mobility is high. The size of the network and the traffic load affects protocols based on source routing like DSR to some extent. A large network with many mobile nodes and high offered load will increase the overhead for DSR quite drastically. By observation a hop-by-hop based routing protocol like AODV is more desirable.
