摘要：

为实现地下无线传感器网络高可靠通信及无线能量传输，针对 VLF 频段提出一种二维蜂窝磁感应网络结构，并建立系统模型。通过电流色散方程对系统带宽、群速和波束赋形等进行推导分析。应用四阶龙格库塔方法对磁感应波的传播进行了时域仿真。结果表明，蜂窝磁感应网络可实现磁感应波的全向传播，与方形栅格网络相比，在各传播角度上具有更加均一的带宽、群速，可应用多天线协作技术实现定向通信和输能，适于在地表下环境建立高连通度、高能效的传感器网络。

Abstract:

To realize the high reliable communication and the wireless power transmission in the wireless underground sensor network,a new type of 2D honeycomb magneto-inductivenetwork was put forward at VLF band.The system model was established,and bandwidth,group velocity and beam forming technologies were researched based on the cur-rent dispersion equations.Simulation with Runge-Kutta method was carried out to verify the efficiency of the network.The result show that the omnidirectional propagation can be realized in the proposed honeycomb network with more bal-anced bandwidth and group velocity in every direction compared with the square lattice structure.Directional communi-cation can also be realized based on the cooperative multi-antenna technology.The proposed honeycomb mag-neto-inductive network is very suitable to build wireless sensor networks with high connectivity and power efficiency in the underground environments.

Key words: wireless underground sensor network, magneto-inductive network, VLF, beam forming
