Methodology of Countering Attacks for Wireless Sensor Networks Based on Trust

摘要

This article discusses the development of methodology of countering attacks based on the use of Bayes' theorem and normal distribution, where the workload, node residual energy, as well as an analysis of successful and unsuccessful network events used to compute the trust level. Estimation of the workload and the residual energy allows detecting attacks such as "Denial of Service", "Sybil" attacks directed on depletion of host resources. Direct trust calculation allows detecting "Black hole", "Grey hole" and "Wormhole" attacks. For the implementation of this methodology the software that can be installed on the base station and the network nodes was developed.
