Abstract
Mobile ad-hoc networks are widely used in the tactical battlefield, emergency search and rescue missions. They are also well used in civilian ad-hoc situations like conferences and classrooms due to the ease and speed in setting up such networks. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The wireless ad- hoc networks are mostly vulnerable to security attacks because of its features of open medium, dynamic topology, lack of centralized management and node mobility. In this paper we proposed a means to inject black hole attack and wormhole with a protocol Ad-hoc On Demand Distance Vector (AODV) and conducted experiments using NS2 simulator. The results show that performance of network decreased in presence of attacks.
