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 depend upon topologies, router source etc. This paper describes the research work done in recent and new mechanism to estimates the network congestion and avoiding them, so that network performance will improve. Our goal in this paper is to achieve high throughput and low end to end delay in congested network.
