Experiment based analysis of ZigBee transmissions under severe Wi-Fi interference

Abstract

To evade Wi-Fi interference for ZigBee networks, it is required to reliably deliver critical channel-changing instructions under heavy interference. This paper firstly investigates ZigBee transmission performance under real-world Wi-Fi and under controlled high-rate data streams, respectively. Based on the experimental results, a theoretical model and a rough guideline for reliable message delivering are presented and analyzed. Further behavior-level simulations confirm the analysis results and provide a strategy for reliably delivering messages under heavy interference, i.e. a nearly-100% success rate with a reasonable delay time.
