| 摘 要： | 利用无线传感器网络可细粒度地感知农田环境参数，但农田中的无线传感器网络链路质量差、接收率低，不能准确及时地收集信息。针对该问题，通过分析大量现场采集数据发现农田中无线链路的质量具有稳定性和局部性的规律，提出2个链路度量因子：平均连续成功发包次数和最近连续成功发包次数。模拟实验结果表明，将这2个链路度量因子应用到路由协议中可有效提高网络接收率。

| Abstract: | Environmental parameters of farmland are essential agricultural information, while Wireless Sensor Network(WSN) provides a fine- grained way to perceive the information. In transmission of sensor data along wireless network in farmland, there is much worse link quality than bare land and overall low delivery rate, which brings great difficulty to accurate collection of information in time. This paper introduces two link estimator factors named average continuous successful transmission count and late continuous successful transmission count, based on overall stability and locality of wireless links quality of farmland. The results of network simulation of a route algorithm integrating with the factors shows an effective enhancement of overall packet receive rate. |
