Performance Evaluation of AODV with and without Black hole Attack in MANETs

Abstract

A Wireless ad-hoc network is a temporary network where several mobileindependent nodes can move freely in any direction. With the help of routing protocols source node locates a path to the target node and forward data packets through intermediate nodes.However, due to mobility and ad-hoc nature, security becomes an important issue in MANET because once malicious nodes are in the range of networks; they can join the network freely and degrades the performance by attacking it. The vulnerability of MANET is very high towards routing attacks such as blackhole, which drops all the packets instead of forwarding it to the targeted node andresults in data loss. This research paper focuses on analyzing the performance of AODV with various parameters such as throughput, packet delivery ratio, normalized routing load and average end-to-end delay using different scenariosof network configuration with and without blackhole attack in MANET.
