Wireless Sensor Network Node Since Localization Algorithm

该文提出了一种基于RSSI测距技术的DV-Hop定位算法。该算法有效利用每跳的统计信息并结合RSSI测距技术,在不增加传感器节点的硬件开销的基础上有效提高定位精度和扩大定位范围。实验表明了提出的方法在不同的节点比例和节点数的情况下,定位误差和定位范围等性能与传统的定位算法相比有明显的提高,是一种有效的方法。

This paper proposes a RSSI ranging technology based on the DV-Hop localization algorithm.This algorithm is effective use of each jump statistical information and combined with RSSI ranging technology,without any increase in sensor nodes on the basis of the hardware interface effectively improve the location accuracy and expand positioning range.Experiments show that the proposed approach in different nodes proportion and the number of nodes circumstance,positioning error and positioning properties such as the scope of compared with the traditional algorithm is improved greatly,is a kind of effective method.
