Applicability of Generalized Metropolis-Hastings Algorithm to Estimating Aggregate Functions in Wireless Sensor Networks

by Martin Kenyeres and Jozef Kenyeres

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 5, Page # 224–236, 2020; DOI: 10.25046/aj050528

Abstract:

Over the last decades, numerous distributed consensus-based algorithms have found a wide application as a complementary mechanism for data aggregation in wireless sensor networks. In this paper, we provide an analysis of the generalized Metropolis-Hastings algorithm for data aggregation with a fully-distributed stopping criterion. The goal of the implemented stopping criterion is to effectively bound…
