MNI-AODV: Analytical model for attack mitigation using AODV routing in ad hoc networks

Research towards securing ad hoc networks has focused on numerous algorithms for detecting intrusions in specific kinds of attacks like black hole, sequence number, neighbor and packet forwarding attacks. In this attempt, impact of malicious node in ad hoc environment is discussed and implemented using ns2 in case of packet dropping attack. In this paper, MNI-AODV algorithm is proposed by incorporating malicious node isolation (MNI) method in EIDS-AODV [3] into an account. In this paper, methodology is proposed against malicious nodes by using MNI-AODV from an ad hoc environment. This paper also highlights the impact of malicious nodes in the presence of packet dropping attack. Further, Analytical model of proposed algorithm is presented using Rational Unified Process tool.
