Adaptive Misbehavior Detection in Wireless Sensors Network Based on Local Community Agreement

In this paper are discussed detecting misbehavior mechanisms in ad hoc wireless sensors´ network. Term misbehavior is understood quite widely. A fake-positives, communication error, spreading false information are treated as sorts of misbehaviors. A cause of those phenomena is insignificant; it can be hardware failure, environment impact or purposeful hostile action. The main idea of this work is to propose efficient and simple algorithms capable to detect misbehaviors basing only on local community agreement. Additionally adaptive mechanism should provide isolation of faulty components. Using proposed mechanisms it is possible to reduce the disturbances, fake positives or invalid alarms in sensors fields
