BNWSN: Bayesian network trust model for wireless sensor networks

In this paper we extend our previously designed trust model in wireless sensor networks to include both; communication trust and data trust. It has been argued that if the overall trust is based on just one trust component, then it might mislead the network, and result in total breakdown of the network. Hence we introduce a new Bayesian network trust model to combine more than one trust component; communication trust and data trust in our case; to produce the overall trust. The model is robust and generic, which allows more trust components to be added to and/or removed from the model very easily.
