This document discusses techniques for detecting malicious packet dropping in wireless ad hoc networks. It begins with an introduction to wireless ad hoc networks and the security issues they face, such as packet dropping attacks. It then reviews existing literature on detecting such attacks using techniques like reputation systems. The document proposes a new detection mechanism that calculates the auto-correlation function of packet loss bitmaps to identify correlations between lost packets and determine if packet dropping is intentional. It describes the key phases of this approach, including key generation, auditing suspected nodes, and detecting malicious nodes. Finally, it discusses using randomized routing to mitigate the effects of detected packet dropping attacks.
