摘要：A Security threat in MANET (Mobile Ad hoc Network) is an important issue because of the numerous attacks. Its routing protocols are vulnerable to unattended installation of sensor nodes in the environment causes these security threats in the Ad-hoc networks. The security of the DSR and AODV protocol is threaded by some kind of attacks such as Black Hole attack and Gray Hole attack. In this work, a novel technique has been proposed to detect and prevent the two types of attacks (Black hole attack and Grey hole attack) which cause more damage to the routing performance of MANET. the impact of these attacks on MANET has been compared also. Here, the AODV routing protocol is improved and simulated in MATLAB.
