Correlated Node Behavior in Wireless Ad Hoc Networks: An Epidemic Model

Correlated node behaviors pose a great challenge for normal functioning of wireless ad hoc network. Their impact could be devastating if the propagation of correlated node behavior will result in network failure. We model correlated node behavior by characterizing the node behavior transition based on Semi Markov process and node propagation based on mathematical model of epidemic theory The focus of this work is to predict how misbehavior node (malicious and selfish) propagate which is important for understanding their potential damages, and for developing countermeasures to secure and survivable wireless ad hoc network. Through modeling and analysis, the results are generally applicable in understanding the propagation rate of correlated node behavior.
