Reducing Network Overhead in Mobile Ad–hoc Network Using Hybrid cryptography techniques

Sangeetha M, Vijayakumar R

Abstract :

Now a day we used many applications based on the mobility and scalability. Among all the up to date wireless networks, Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. MANET consists of mobile nodes which are free to move arbitrarily. MANETs are highly vulnerable for passive and active attacks because of their open medium, rapidly changing topology, lack of centralized monitoring. Both of the TWOACK and Watchdog methods solutions, which are considered as the first line of defense, are not sufficient to protect MANETs from packet dropping attacks. And the new intrusion–detection system named Enhanced Adaptive ACKnowledgment (EAACK) specially designed for MANETs. But this technique also having some potential issues like network overhead, collusion and partial dropping. In this paper, we propose and implement a new technique called Hyid cryptography specially designed for reduce network overhead. Due to this, it improves network performance.
