Advanced Secure System For Manet

Mobile Ad Hoc Networks (MANETs) are fundamentally different from their wired-side counterparts. MANETs provide no fixed infrastructure, base stations or switching centers. So there is no security to protect the nodes in the network. Each and every nodes act as a sender and receiver. Each node helps each other to perform network functions in a self organization way. However, some nodes in a network may oppose to cooperating with others to avoid consuming their battery power and other resources. So we propose and implement a new Intrusion detection system called Enhanced Adaptive Acknowledgement (EAACK). EAACK identifies the malicious nodes and improving the performance of the network
