A MANET is a set of mobile nodes which works in a dynamic changing network and it is capable of communicating with each other efficiently where all the nodes perform a dual role as that of a transmitter and a receiver. Hence MANETs do not use any centralized administration for communication due to this reason they are more vulnerable to attacks. So MANET uses special technique called EAACK, which uses special acknowledgment messages to avoid intruder communication. So due to this type of authentication, more acknowledgment messages are transferred in between two nodes, which increases delay in communication. Hence this drawback reduces system performance.
In this paper we propose a new clustering technique in EAACK called CEAACK. Our proposed technique shows better performance when compare to the normal EAACK technique, which drastically reduces the number of acknowledgment packets during authentication process which achieves a good energy efficiency network and better data transmission.
Further, this technique consumes low energy and in the process provides better efficiency in data transmission in MANETs.
