A REVIEW ON CONGESTION CONTROL IN AD-HOC NETWORK?

In wireless network communication mobile network communication has becomes very important. Manet is a temporary network that means nodes moves without any fixed infrastructure. In Manet nodes are generally communicated with each other over various wireless links and also changes network topologies due to nodes are movable. Routing is a problem in Manet because there is no router between source & destination so; mobile nodes themselves act as the routers. In Manet, routing depand upon topologies, router source etc. In Manet, congestion control is a major problem. Congestion means when transmission of number of packets across the network is greater than the capacity of the network then network becomes congested. Due to congestion packets have to be dropped and also decrease the performance of the network. So, finding the congestion free shortest path is a main issue in Manet. To avoid this problem we apply a fuzzy based algorithm.
