摘要/Abstract

摘要：

Because of its potential applications in agriculture, environment monitoring and so on, wireless underground sensor network (WUSN) has been researched more and more extensively in recent years. The main and most important difference of WUSN to terrestrial wireless sensor network (WSN) is the channel characteristics, which determines the design methodology of it. In this paper, the propagation character of electromagnetic (EM) wave in the near surface WUSN is analyzed, as well as the path loss model of it is given. In addition, the influence of human’s ankle to the channel characteristics of near surface WUSN is investigated by electromagnetic theory analysis, simulation and experiment. A novel path loss model of near surface WUSN which takes the interference of human’s ankle into consideration is proposed. It is verified that the existing of human above the WUSN system may cause additional attenuation to the signal of near surface WUSN which propagates as lateral wave along the ground. Moreover, the relation of the attenuation and operating frequency is deduced, which gives a reference to extend the frequency band applied in WUSN.
