The research of black hole detection in AODV based on NS2

摘要

With the widespread applications of the mobile Ad Hoc network, the security problems are getting more and more attention. Among all the problems, routing security is the main one. In this paper, Ad Hoc on Demand Distance Vector (AODV) was used as an example to analyze the principle of AODV and the threats it faces. A black hole node detection scheme based on acknowledgement (ACK) message mechanism was proposed contraposing the characteristics of black hole attack. Simulation results show that this method has a good performance in detecting black hole node.
