Abstract
We consider the problem of modeling and analyzing the application communication reliability of hierarchical clustered wireless sensor networks (WSN) in this paper. We propose reliability measures that integrate the conventional connectivity-based network reliability with the sensing coverage measure of WSN. And we apply a reduced ordered binary decision diagram (ROBDD) based progressive approach for evaluating the proposed coverage-oriented application communication reliability. We illustrate the basics and advantages of our approach by working through the analysis of an example WSN.
