The Mobile Ad hoc Network (MANET) is composed of a large number of self-configuring mobile nodes to form the network. Due to the mobility of the nodes, the architecture has been changed frequently. Since the nodes are battery operated and limited in nature, hence it is too difficult to replace or charge the battery sooner possible. In order to extend the life time of the nodes in the network variety of energy efficient protocols have been proposed. This paper is analyzed the problem of congestion control in the nodes. In this work the congestion control is achieved by implementing the Congestion and Energy Aware Routing Protocol (CAERP). In order to achieve the congestion free communication with minimized energy utilization the data rate of the individual nodes are changed according to the queue state and signal strength identifier. If the value of the Received Signal Strength Indicator (RSSI) is low, it is assumed that the distance between the sources to sink is high and vice versa.The RSSI and the queue size of the nodes in the ongoing path are used to adjust the data rate of the intended node transmission. It achieves the high link reliability for current transmission path and optimum energy utilization. The proposed protocol is compared with existing techniques and implemented in NS2 network simulator. The simulation results proved that the proposed one reduces the packet drop, energy utilization, congestion and improves the life time of the entire network.
