Abstract

Advancement in wireless technologies and improved use of wireless devices demands more infrastructure-less networks like MANET. Security of such a scenario is a challenging task over last few years. Because of its distinctive characteristics such as open medium and dynamic network topology, MANET can be accessible to malicious users. Black hole attack is one of serious threat in mobile ad hoc network, in which malicious node absorbs the packets instead of forwarding them to destination. In the proposed work Black hole attack in the network is detected and eliminated in two phases. Black hole attack is detected using a watchdog mechanism, which is the basis of different Intrusion Detection System (IDS) along with an acknowledgement scheme. After identifying the attack, the proposed system removes black hole node from the path and provide a new route to destination.

Keywords: MANET, Intrusion Detection System, watchdog, Acknowledgement Scheme
