Mobility causes frequent link failure which results in packet losses. TCP assumes that these packet losses are due to congestion only. This wrong assumption requires packet retransmissions till packet arrives successfully at the receiver. Goal is to improve TCP performance by using signal strength based cross layer approach which obviously resolves the congestion. We are reviewing a signal strength based measurements to improve such packet losses and no need to retransmit packets. Node based and link based signal strength can be measured. If a link fails due to mobility, then signal strength measurement provides temporary higher transmission power to keep link alive. When a route is likely to fail due to weak signal strength of a node, it will find alternate path. consequently avoids congestion. We will make changes at MAC routing and routing layer to predict link failure. MANET hits the protocol's strength due to its highly dynamic features, thus in testing a protocol suitable for MANET implementation we have selected two routing protocols AODV and DSR. Packet Delivery Ratio, Packet Drop, Throughput and end to end delay are the metrics used for performance analysis of the AODV routing protocols.

So there is a requirement of new MANET routing protocol having low rate message overhead. Hence it is necessary to enhancement the performance of MANET. The reduction of routing overhead decreases the usage of bandwidth of the network. The increase of bandwidth will increase the throught and decrease the latency of the nodes of the network. This Paper proposes the new Routing Protocol which will increase the throughput,reliability and decrease the latency of the network.

The algorithm ant colony optimization algorithm is popular due to its dynamic and adaptive nature in the real time system. It is concerened mainly with ants which find the shortest routing path to food by secreting a substance called pheromone. All the other ants follow the initial ant which took the shortest path from source to destination. When a obstacle or disturbance is faced by any other ant, further finds a new shortest path from source to destination and all other ants follow the new ant.
