摘　　要：探讨绿色农业物联网的设计问题。鉴于大规模农业物联网具有涉及区域广,传感器数量多和能源供应困难等问题,低能耗物联网的设计便提上的议事日程,绿色物联网设计就要求降低能耗。对绿色物联网设计提出一种新的拓朴结构,网络具有传感器层和广域网接入层两层结构,融合了GPRS和WLAN网络协议,能够实现农业场景的大范围网络覆盖,并利用主从式传感器实现到基站的数据传输。利用OMNeT++软件,建立一个仿真平台来实现这种设计,并利用该仿真平台进行了网络通信能耗的分析,结果证明了与单层网络相比,两层结构降低了能耗。这个设计为为构建实用绿色农业物联网奠定了一定基础。This paper deals with the problem of design of green agricultural Intemet of Things loT. The large-scale agricultural IoT holds the features of wide area, a great amount of sensors and lack of power support. The key point of green agricultural IoT is to reduce the power consumption. This paper presents a new topological structure for the green agricultural loT which has two layers, of sensor layer and LAN access layer, combines GPRS and WLAN network protocols to realize a wide coverage, and applies mas- ter-slave structure to transmit data from sensor to base station. Based on OMNeT＋＋ a simulation platform is built to illustrate the validation of the design. By analysis of simulation result, the two-layer network decreases the power consumption, and provides a foundation for the establish of real green agricultural IoT.
