Consensus-based filter designing for wireless sensor networks with packet loss

摘要

In wireless sensor networks (WSNs) and networked control systems (NCSs), packet loss is inevitable. If the node loses measurement data, then the estimation performance will degrade. In this paper, a novel filter based on consensus algorithm for packet loss is designed in order to increase estimation accuracy and reliability. Firstly we develop a packet loss model with a stochastic Bernoulli binary switching sequence. Then a novel filter that can tolerate packet loss is designed with consensus strategy and the orthogonal analysis approach. Finally, simulation results show that comparing with existing methods the proposed filter has superior performance.
