  • Title: Distributed parameter estimation in unreliable sensor networks via broadcast gossip algorithms.
    Author: Wang H, Liao X, Wang Z, Huang T, Chen G.
    Journal: Neural Netw; 2016 Jan; 73():1-9. PubMed ID: 26490219.
    Abstract:
    In this paper, we present an asynchronous algorithm to estimate the unknown parameter under an unreliable network which allows new sensors to join and old sensors to leave, and can tolerate link failures. Each sensor has access to partially informative measurements when it is awakened. In addition, the proposed algorithm can avoid the interference among messages and effectively reduce the accumulated measurement and quantization errors. Based on the theory of stochastic approximation, we prove that our proposed algorithm almost surely converges to the unknown parameter. Finally, we present a numerical example to assess the performance and the communication cost of the algorithm.
