In this paper, the authors considered the problem of detecting whether a compromised router is maliciously dropping packets in the network. Packet dropping from a network of two reasons those is congestion route and malicious attacks. In particular, they are concerned with a simple yet effective attack in which a router selectively drops packets destined for some victim. Unfortunately, it is quite challenging to attribute a missing packet to a malicious action because normal network congestion can produce the same effect. Modern networks routinely drop packets when the load temporarily exceeds their buffering capacities. Previous detection protocols have tried to address this problem with a user-defined threshold value but in this method they added the buffer size dynamically, because of this congestion get removed as possible.
