Recently, it was pointed out that many popular consensus-based time synchronization algorithms, such as Average TimeSynch (ATS), are all divergent in a network with arbitrarily small random communication delays under any interconnection topology. This note proposes a least-squares estimation-based time synchronization (LSTS for short) algorithm. This algorithm modifies the ATS algorithm in relative...
This paper investigates how to determine the nodes' locations in wireless sensor networks (WSNs) with only distance measurements. We extend our formation algorithm given in [1] to this localization problem. This extension includes three terms: the estimation of initial position, time-varying step size and decaying coefficient. It is verified that excellent performance can be derived, and the global...
