摘要

本文提出了一个基于并行时域有限差分(FDTD)方法的仿真环境，用于无线身体传感器网络(WBSNs)中特定主题的无线电信道建模。仿真环境在信道建模中考虑了真实的天线辐射方向图，分析了它们对wbsn的影响。将所提出的仿真工具应用于医院环境中身体通信通道的研究，并通过现场测量验证了结果。我们的研究发现，WBSNs的无线电频道特征具有受试者特异性，并与人类性别和体重指数(bmi)有关。

A Simulation Environment for Subject-Specific Radio Channel Modeling in Wireless Body Sensor Networks

This paper presents a simulation environment, based on the parallel finite-difference time-domain (FDTD) method, for subject-specific radio channel modeling in wireless body sensor networks (WBSNs). The simulation environment takes into account realistic antenna radiation patterns in channel modeling to analyze their effects on WBSNs. The proposed simulation tool is applied to a study of body communication channels in a hospital environment and the results are validated by site measurement. It is found from our study that radio channel characteristics in WBSNs are subject specific and associated with human genders and body mass indices (BMIs).
