A Novel Congestion Avoidance Based Load Balanced Routing with Optimal Flooding in Mobile Ad hoc Network

The QoS of Mobile Ad hoc Network is mostly affected by the congestion at any intermediate node in a selected routing path. In this paper, we propose a congestion avoidance basedload balanced routing scheme for mobile ad hoc network. Each node keeps track of the number of data packets transmitted byhim as well as the data packets transmitted by its one hop neighboring nodes along with their flag bit status for the currenttime interval. The proposed approach is attempts to avoid thecongestion of a node by selecting the disjoint paths. This is achieved by setting a flag bit with the time limit TTL, at the node. On exceeding of this value, the flag bit is reset. By this approach we have attempted to limit the flooding and congestionof the node along with effective balancing of the traffic load
