A Dynamic Channel Assignment for Coexistence of ZigBee/WiFi
Tao Chi, Haowei Yan · 2017
In an Agricultural Internet of Things (AIOT) system, there are a variety of wireless communication devices working simultaneously and producing interference due to using different protocols.In this paper, the problem on coexistence of ZigBee/ WiFi in AIOT is analyzed and a dynamic channel assignment method is proposed.ZigBee network defects interference and switches channel quickly to avoid the interference of the WiFi network while packet loss rate exceeds the critical value.In order to reduce energy consumption of nodes, this paper proposes power control technology based on communication distance.Experiments show that ZigBee can basicly avoid WiFi interference.
