Mobile ad-hoc Networks (MANETs) and Delay Tolerant Networks (DTN) rely on network cooperation schemes to work properly. Nevertheless, if nodes have a selfish behaviour and are unwilling to cooperate, the overall network performance could be seriously affected. The use of watchdogs is a well-known mechanism to detect selfish nodes. Nevertheless, the(More)
Watchdogs are a well-known mechanism to detect threats and attacks from misbehaved and selfish nodes in computer networks. This paper proposes a collaborative approach for detecting black holes and selfish nodes in MANETs, using a set of bayesian watchdogs which collaborate to enhance their individual and collective performance. To evaluate the performance(More)
