A mobile ad-hoc network is an autonomous system, no infrastructure and mobile nodes connected by wireless network. Every mobile nodes in the MANET network is free to move any place and any time any direction in independently. It will change its links to other node continuously. Link and malicious packet dropping are two sources for packet losses in MANET. In the insider-attack case where by malicious nodes that are part of the routing their knowledge of the communication context to selectively drop a small amount of packets less to the network performance. The proposed solution is efficient way to detect and prevention of various packet dropping attacks using Intrusion Detection System (IDS). Sleep scheduling algorithm is used nodes to be awake in a given period same time remaining nodes are in sleep position to minimize energy consumption and enhance the energy efficiency with high performance
