In wireless sensor networks the packet droppers and modifiers are common attacks. It is very difficult to identify such attacks and this attack interrupts the communication in wireless multi hop sensor networks. In this the authors can identify the packet droppers and packet modifiers using ranking algorithms and packet marks. The performance is represented using detection rate and false positive probability. So packet dropping and modification are common attacks that can be launched by an adversary to disrupt communication in wireless multi hop sensor networks.
