Abstract: MANET is one of the important and improving networks in many applications. In MANET, the nodes in the network are self-configuring, without any access points. So, Congestion is considered as important factor which deteriorate the performance of entire network. Due to self-configuring nodes, consumption of energy is high. To avoid this, energy efficiency is needed. In this paper, we developed Energy Efficient Scheme for Congestion Control (EESCC), to improve the energy efficiency of the nodes. Multipath routing is needed to control congestion. Retransmission of packets is minimized by calculating the data energy level and acknowledgement packets. With the help of extensive simulation, this scheme provides minimum consumption of energy and high packet delivery ratio and low delay.
