无线传感器网络在精细农业中的应用
首发时间:2008-06-18
摘要:无线传感器网络(Wireless Sensor Network ,WSN)技术在精细农业(Precision Agriculture,PA)中存在着巨大的应用价值。然而当前无线传感器网络在精细农业中的应用都采用传统的客户/服务器模型,数据从源端发送到目的端,受精细农业中数据量大、并发性强、信号干扰强及传感器网络资源极端受限的影响,这种客户/服务器模型阻碍着传感器网络在精细农业中应用,导致了当前传感器网络大规模成功应用于精细农业的例子很少。本文提出了一种基于移动代理的传感器网络模型MAPA,通过将计算移到资料源处处理,避免大量农业中间资料的传输,从而延长了传感器网络寿命、促进了传感器网络在精细农业中的应用。

Wireless Sensor Network Solutions for Precision Agriculture
Abstract:Wireless Sensor Network (WSN) technology has the potential to have impact on many aspects of Precision Agriculture (PA). However, current WSN applications in Precision Agriculture all adopt the traditional client/sever model, data are sent from the source to the destination, because of hugeous data, high concurrency and strong signal interference in Precision Agriculture and the extremely limited sensor network resources, such client/sever model hampers WSN applications in Precision Agriculture. This paper presents a mobile-based agent of wireless sensor network model MAPA, MAPA avoids the large agricultural intermediate data transmission through migrating the computing to the resource source, and consequently it prolongs the sensor network lifetime and promotes the WSN applications in Precision Agriculture.
Keywords: Precision Agriculture Wireless Sensor Network Mobile Agent
