Securing Manet to Avoid Intrusion Using Enhanced Adaptive Acknowledgment Technique

Abstract :

Security has become an important part in Mobile Adhoc Networks because of their dynamic mobility, scalability and shared resources. MANETs is a collection of mobile nodes and it does not require a fixed infrastructure. So it acts as a dynamic topology for many applications. MANETs are highly vulnerable for attacks because of their open medium, rapidly changing topology, lack of centralized monitoring. Both Watchdog and TWOACK methods are not sufficient for protect MANETs in the cases of receiver collision, limited transmission power and false misbehavior report. To overcome such attacks the proposed technique is a secure intrusion-detection system named Enhanced Adaptive ACKnowledgment (EAACK) specially designed for MANETs
