Abstract
In packet-drop attacks in ad hoc networks, a malicious network node chooses to selectively drop packets that are supposed to be forwarded, which results in adverse impact on application good-put and network stability. A method and system for detection of packet-drop attacks in ad hoc networks requires network nodes to report statistics on IP flow packets originated, received, or forwarded to neighbors. These statistics are analyzed and correlated to determine nodes suspected of dropping packets.
