Causing packet loss due to attacks by malicious nodes is one of the most important problems in MANETs. There are many ways by which packet loss can occur in MANETs such as broken links, transmission errors, no route to the destination and attacks caused by malicious nodes. To determine the exact cause of packet loss in wireless network is a challenging task. In this paper, the authors have investigated packet loss problem caused by a malicious nodes that performs the well known attack called BlackHole attack in the network. To mitigate the effects of such attack, they have also proposed a detection technique that efficiently detects the malicious nodes in the network. They have done simulations using NS-3 simulator.
