摘要: 针对现有沙尘暴预测系统具有高密度部署等不足,研究面向沙尘暴监测的无线传感器网络(WSN)连接问题。考虑沙尘暴影响下的信道具有多样性/多变性的特点,给出基于渗流理论的多种信道分析方法,证明联合使用多种信道可明显提高网络连接性能,进而提出一种切实可行的面向沙尘暴监测的WSN接入切换方法。研究结果表明,利用该方法的WSN架构能够建立高效的沙尘暴监测系统,为沙尘暴的有效防治提供一种监测途径。

Abstract: 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.

Key words: Wireless Sensor Network(WSN), channel model, network connectivity, sandstorm monitoration, network architecture, critical density
