Mobile adhoc network is an infrastructureless network with a dynamic native where the nodes are free to move and hence it is susceptible to various attacks.Previous system is an acknowledgement based intrusion detection system where there is a high energy condumption due to the inefficient path selection where the selected nodes energy is drained before completing the communication and also due to the flooding of hello packets to unavailable nodes.The previous IDS also has the disadvantage of pre distribution of keys which can be easily accessed by the malicious attacker which can forge the acknowledgement packets which is confirming the packet delivery.The acknowledgement packet is when forged, the false information will be delivered to the source about the honest nodes which has already successfully forwarded the packet.This project deals with the problem of high energy consumption and also attack caused by pre distribution of the keys.The acknowledgement packets are digitally signed using a session key in order to avoid the forging of the acknowledgement packets.The energy consumption is reduced by using an energy efficient path selection method where efficient nodes are selected and also by suppressing the hello packets which is sent to the unavailable nodes.Simulation tool used in this project is ns2.35 .Simulation result shows that the proposed scheme provide a reasonably good level of security and reduced energy consumption than the existing system.This system is used in the military applications,banking etc.
