A Study on improved version of Enhanced Adaptive Acknowledgement (EAACK) Called EAACK2 in MANETs

Abstract

Mobile ad hoc network (MANET) is a collection of autonomous mobile nodes with infrastructure less network .In MANET, the mobile nodes are equipped with both wireless transmitter and receiver that communicate via bi-directional wireless links. Moreover, the mobile nodes are self configuring and self organizing in nature, these unique characteristics made MANET ideal to be deployed in a remote or mission critical area like military use or remote exploration. However, the open medium, wide distribution of nodes and changing topology and lack of centralizing monitoring in MANET leave it vulnerable to various means of attacks. It is difficult to develop suitable intrusion detection scheme to protect MANET from malicious attackers. In this paper, we introduce an improved version of EAACK called EAACK2 that helps in detecting forged acknowledgement and performs well in the presence of false misbehavior and partial dropping.
