Detect Packet Forward Algorithm for Intrusion Discovery in MANET using Misbehaviour Report Authentication

Abstract: Mobile ad-hoc network is a kind of wireless ad-hoc network, and is a self-configuring network of mobile routers connected by wireless links the union of which forms an arbitrary topology. Mobility and scalability brought by wireless network made it possible in many applications, Digital signatures frequently used for distribution of messages from sender to receiver ,It certificate serve as a proof of an authentication for individual data packets. The DPF e is designed to resolve the weakness of Watchdog when it fails to detect misbehaving nodes with the presence of false misbehaviour report. The core of DPF algorithm is to authenticate whether the destination node has received the reported missing packet through a different route. With the improvements of the technology and cut in hardware costs, we are witnessing a current trend of expanding MANETs into industrial applications. To adjust to such trend, we strongly believe that it is vital to address its potential security issues. In this paper, we propose and implement a new intrusion-detection system named Enhanced Adaptive Acknowledgment (EAACK) specially designed for MANETs. Compared to contemporary approaches, EAACK demonstrates higher malicious-behavior-detection rates in certain circumstances while does not greatly affect the network performances
