Abstract: In recent years ubiquitous network connectivity and mobility are rapidly gaining significant importance. MANETs and wireless mesh networks are able to cover the arising needs. However, multi-hop communication relying on the cooperation of customer nodes leads to severe security issues. Although secure routing protocols and mechanisms to detect routing misbehavior in the direct neighborhood exist, collusion of misbehaving nodes overrides current security mechanisms. We present LeakDetector a mechanism that detects colluding malicious nodes in multi-path routes. LeakDetector can be used with proactive secure routing algorithms to calculate for each node participating in a multi-path route its individual data loss ratio. Depending on this ratio, the node is considered as malicious. Evaluation shows, that LeakDetector provides a near-optimal detection rate with almost no false positives
