Localisation is one of the most important services in sensor networks. The impact of the used localisation technique used reflects on wireless sensor network services such as coverage or event detection. Accuracy is considered to be one of the factors that is related to successful network performance in most sensor network applications. Communication ranging is one of the practical applicable technique for localisation on short-range communication nodes with no additional components. This study proposes an enhanced communication ranging localisation technique with high accuracy. The authors evaluated and validated the proposed technique in a forest environment using 20 Waspmote Nodes and Meshlium router (Spanish product). The novelty of the proposed localisation technique is based on controlling communication range by manipulating the XBee transmitter power changing ability on four rounds to provide the best-predicted location. The results demonstrated the locations of nodes were found with error range between 0 and 22 m. The network location error decreased starting with 30 m in round 1 down to 8 m in round 4. The technique can be applied to different types of networks and technologies as long as the transmission power can be set to different values and the communication range is known or can be measured manually.

基于通讯测距提高无线传感器网络定位的准确性

本地化是传感器网络中最重要的服务之一。使用的所用定位技术的影响反映在无线传感器网络服务上，例如覆盖范围或事件检测。精度被认为是与大多数传感器网络应用中成功的网络性能相关的因素之一。通信测距是用于在没有附加组件的情况下在短距离通信节点上进行定位的一种实用的实用技术。这项研究提出了一种高精度的增强的通信测距定位技术。作者使用20个Waspmote节点和Meshlium路由器（西班牙产品）在森林环境中评估并验证了所提出的技术。所提出的定位技术的新颖性是基于通过四轮操纵XBee发射机功率变化能力以提供最佳预测位置来控制通信范围。结果表明，发现节点的位置误差范围在0至22 m之间。网络位置误差从第1轮的30 m开始下降到第4轮的8 m。该技术可以应用于不同类型的网络和技术，只要可以将传输功率设置为不同的值并且已知通信范围即可或可以手动测量。
