摘要:Mobile ad-hoc networks (MANETs) are forced to cooperate in order to work properly. This cooperationis a cost effective activity and some nodes can refuse to cooperate with other nodes that leading to selfish nodebehavior. This is how the overall network performance will be seriously affected. The use of watchdogs is a wellknown mechanism to detect selfish nodes but this watchdog process fails due to generating false positives and falsenegatives that can induce to wrong operations and also relying on local watchdogs alone can lead to poor performancewhen detecting selfish nodes, in term of precision and speed. This is especially important on networks with periodiccontacts, such as delay tolerant networks (DTNs), where sometimes watchdog’s lack of enough time or information todetect the selfish nodes. This study proposes an Evidence of Behavior Information Exchange (EBoX) scheme as acollaborative approach based on the diffusion of local selfish nodes awareness when a node is compromised by externalattackers. The EBoX approach reduces the packet transmission time and increases the precision by detecting thecompromised nodes attacked by selfish nodes. The EBoX helps to avoid partial selfish nodes using anonymizationtechnique, this technique hides the nodes original identity and provides an anonymous access, this helps to avoid partialselfish nodes in the network. Reputation values will be calculated according to their contact log and transmission logs.
