Abstract :

Mobile ad hoc networks (MANETs) have attracted much attention due to their mobility and ease of deployment. It allows wireless nodes to form a network without requiring a fixed infrastructure. However, the wireless and dynamic make them more vulnerable to various types of attacks. Thus the major challenge is to guarantee secure network services against several attacks. Black hole attack is one of the severe security threats in ad-hoc networks. Several Intrusion detection systems (IDS) have been proposed but there is a problem when the IDS node fails and also overhead due to information exchange between the IDS nodes is more. In this paper, Improved Credit-Based Geographic Routing Protocol(ICGRP) is implicated for securing the network against Black hole attack by credit value estimation for each node in the network based on the route request (RREQ) sent by the node along with Dynamic Source Routing(DSR). Also the mobility constraints are identified by GPS enabled position update scheme to predict the location of destination nodes. In order to maintain accurate local topology for the on-going data forwarding activities On-Demand Learning rule (ODL) is used. The performance metrics such as Packet Delivery Ratio, End- to- End delay, Energy Consumption and Packet loss has been evaluated and the result is validated by using NS 2.35 simulator. Keywords: Black hole attack, ODL, GPS, ICGRP, Credit value
