WITHDRAWN: A novel proactive routing strategy to defend node isolation attack in MANETS

Abstract

Routing protocols designed for MANETs are, in general are highly vulnerable to various forms of security attacks. A routing protocol is vital to the functioning of a wireless ad hoc network, and hence, security needs to be present to negate any potential malicious influences. However, providing efficient security mechanisms for such routing protocols is still viewed as being a considerable challenge. This paper proposes a novel proactive routing strategy to provide the security for MANETs to make the network secure from the node isolation attack. Node isolation attack occurs for the target node by the attacker after observing the network activity. The proposed approach enhances the security by verifying the hello packets from all of its neighboring nodes coming from a new node before choosing it as a multi-point relay (MPR) for data packets. Extensive simulations carried out over the proposed strategy illustrate the outstanding performance with respect to the packet loss rate and throughput .
