In multi hop wireless ad hoc networks the packet loss can be occurred by two sources they are link errors and malicious packet dropping. It is important to find whether the losses are due to link errors only or is due to both link error and malicious packet drop. The malicious nodes present in insider attacker case selectively drop packets to degrade the network performance. The packet dropping in this case is nearly equal to the normal link error because of which existing algorithm that are based on detecting the packet loss rate cannot find the exact cause of packet loss.
