PROTECTION OF WIRELESS SENSOR NETWORKS IN INDUSTRIAL AUTOMATION

S. Vivek Saravanan and A. Solairaju

We analyse a fundamental overview of information security and discusssome examples used throughout the rest of the paper. Our security engineering methodology is presented. This paper also presents the definition and evaluation of a new protocol for providing a wireless sensor network (WSN) with ahierarchical organization. Differently from previously proposed solutions, protocol, “clique clustering” includes in its operation a fail-safe mechanism for dealing with node failure or removal, which are typical of WSNs. The network is partitioned into clusters that are cliques (nodes in each clusters are directly connected to eachother’s). An efficient mechanism for building a connected backbone among the clique clusters is provided. Clustering, backbone formation and backbone maintenance are completely localized, in the precise sense that only nodes physically close to a failing node are involved in the reconfiguration process
