Abstract:

A Wireless Mobile ad-hoc network (MANETs) is a temporary network set up by wireless mobile nodes moving self-assertive in the spots that have no system foundation. Security is one of the major issues in MANET due to dynamically changing topologies, limited resources lack of centralized monitoring, open medium and bandwidth constraint. In Grayhole attacks malicious nodes disrupt data transmission in the network by sending incorrect routing information.. In this paper, we propose a scheme for Ad-hoc On-demand Distance Vector (AODV) protocol, in which an intermediate node detects the malicious node sending false routing information; routing packets are used not only to pass routing information, but also to pass information about malicious nodes. The proposed scheme not only detects but also removes malicious node by isolating it, to make safe and secure communication.
