Stealthy packet dropping is a suite of four attacks - misrouting, power control, identity delegation, and colluding collision - that can be easily launched against multihop wireless ad hoc networks. Stealthy packet dropping disrupts the packet from reaching the destination through malicious behavior at an intermediate node. However, the malicious node gives the impression to its neighbors that it performs the legitimate forwarding action. Moreover, a legitimate node comes under suspicion. A popular method for detecting attacks in wireless networks is behavior-based detection performed by normal network nodes through overhearing the communication in their neighborhood. This leverages the open broadcast nature of wireless communication. An instantiation of this technology is local monitoring.
