Performance Evaluation of AODV under Blackhole Attack
Tarunpreet Bhatia, Anil Kumar Verma · International Journal of Computer Network and Information Security · 2013
Mobile Adhoc NETwork (MANET) consists of mobile nodes that can move freely and route packets without aid of centralized infrastructure.Dynamic changing topology, limited battery power and lack of centralized trusted authority make it vulnerable to several attacks and lot of research is being carried out in the field of security by discovering attacks, evaluating the damage caused to the network and developing solutions to combat such attacks.This paper simulates one of the most malicious behaviors known as blackhole attack.The blackhole node creates forged reply, advertising valid and fresh route to destination and thereafter drops data packets maliciously.The analysis guides us to the various performance parameters such as throughput, packet delivery fraction, normalized routing load and number of dropped packets evaluated over different scenarios.
