A Statistical Approach for Reputation Update in Wireless Sensor Networks Under Certainty

In reputation modeling of Wireless Sensor Networks (WSNs), the number of positive and negative outcomes of a certain event is not justified for individual WSN nodes to make decisions, thus certainty should be taken into consideration in the real situation and reputation should be discounted by certainty. In this paper, based on negative binomial distribution and combined with certainty as a discounting factor, a light-weight yet applicable approach for the reputation update in WSNs is proposed.
