Reliability Evaluation for Wireless Sensor Network Based on Weighted Voting System with Unreliable Links

摘要

To evaluate the reliability of WSN whose topology is clustering structure, we model the WSN as a Weighted Voting System (WVS) with unreliable links, and propose an algorithm. The algorithm is based on universal generating function technique, and two composition operators are defined to composite u-functions of member nodes, links and cluster heads. Test results shows that the proposed algorithm can effectively calculate the reliability of WSN whose topology is clustering structure.
