Wireless Sensor Network Access Switching Method for Sandstorm Monitoring

Aiming at many inadequacies of the existing sandstorm forecasting systems,this paper studies the connectivity issue of Wireless Sensor Network(WSN) for sandstorm monitoring.Taking into account such channel has the characteristics of diversity/variability under the impact of sandstorms,the paper gives multiple types of channels analysis method based on percolation theory.It proves that jointly using multiple types of channels improves network connectivity,and proposes a feasible WSN access switching method.Study results show that the WSN architecture based on the proposed access switching method can construct an efficient sandstorm monitoring system,and provide an effective control to sandstorm.
