| 摘 要： | DV-distance是一种基于多跳机制的定位算法,其相邻节点间的距离通过RSSI测距技术实际测量得到。为了减少RSSI测距误差对定位精度的影响,首先对RSSI测距误差进行修正,再对已有的信标节点间计算距离误差修正值的方法作进一步改进,提出一种基于RSSI测距误差修正的改进型DV-distance差分定位算法。仿真结果表明,相比已有的定位算法,该改进算法不仅能提高节点的定位精度,还能减少网络通信开销及计算复杂度。 |

| Abstract: | DV-distance is a localization algorithm based on multi-hop mechanism. It uses the RSSI ranging technique to measure the distance among the neighboring nodes. In order to reduce the in influence of RSSI ranging error on the positioning accuracy, it amended the ranging error of RSSI firstly, and improved the previous computing method of distance error correction among beacons secondly, which proposed an improved DV-distance difference localization algorithm based on ranging error correction. The simulation results prove that the improved algorithm not only can enhance the positioning accuracy effectively, but also can decrease the communication spending and computing complexity compared with the previous algorithms. |
