| 摘 要： | 针对MSP算法需要借助额外的外部扫描设备,不适合应用于对野外大规模部署的传感器网络进行定位这一缺点,提出了一种HG-MSP算法。该算法通过锚节点发出扫描信息,不需要额外的外部设备进行辅助定位,提高了算法的可用性。仿真实验表明,在去掉辅助设备的情况下,算法的定位精度并无明显下降。

| Abstract: | MSP algorithm gets the feedback node sequence using external scanning device to locate the node, and has the properties of fast time and high accuracy. But the MSP algorithm is not suitable for large scale sensor networks deployed in wild field because of the external device. An improved HG-MSP is proposed according to the drawbacks of MSP. The HG-MSP algorithm uses anchor node sending message to locate, with no additional device added. The usability of the algorithm is highly improved. Simulation shows that the accuracy has no significant declines without additional device. |
