This paper provides the energy efficient to identify the selfish node at the time of packet transmission. In MANET, packets are routed from one node to another node through intermediate nodes for communication purpose. The intermediate nodes can act as selfish behavior and will not transfer or forward the packets to neighbor node, thus it save its resources by itself. Thus the overall routine of the network will get pretentious. Watchdog mechanism used t detect the selfish node sometimes leads to failure and it produce a wrong information to the system. The use of watchdog leads to poor performance when detecting the selfish node in terms of speed and precision. Thus we propose an augmented consistent count based mechanism to evaluate the behaviour of the different mobile nodes. From the replication result, the offered approach Energy based selfish node detection terms of performance evaluation metrics such as delay, packet loss, throughput, packet delivery value and overhead. Further this mechanism has a reasonable rate of 20% in isolating the selfish node from the routing path.
