Implementation of New Congestion Control Mechanism in Manet Using Buffer Management

A number of routing algorithms have been established to facilitate routing). However, most algorithms just implement the shortest path routing and do not follow well to MANET characteristics, such as the belief and battery levels of the mobile nodes, critically influence the suitability of the routing decision. Network based congestion avoidance which involves handling the queues in the network devices is an integral part of any network. Maximum of the mobile networks use Drop tail queue management where packets are dropped on queue overflow which is global synchronization problem. This Paper proposes a new scheme of buffer management to control congestion in MANET. We set a buffer from sender to receiver with an X (X is not defined yet) buffer limit. There are several neighboring nodes around that main buffer and every node have its own limit for placing no. of packets in it so that packets should not be dropped.
