Abstract

The invention discloses a 5G super-density network node positioning method based on an H index. The method comprises: calculating H indexes of all nodes in a network; selecting an H index threshold value, marking nodes with H indexes greater than the threshold value as important nodes, and dividing the important nodes into regions; placing micro base stations in the centers of all important nodes in different areas; and by utilizing the 5G macro base station and the micro base station, carrying out jointly positioning the nodes in the network. According to the method, a super-density network with the density larger than that of a common network is considered, all the nodes in the nodes can be effectively positioned by properly arranging the micro base stations in a high-density area, the positioning precision is high, the number of the micro base stations needing to be arranged can reach the minimum, and optimal configuration of network resources can be carried out.

Description

technical field [0001] The invention belongs to the field of network node positioning, and in particular relates to a method for 5G ultra-density network node positioning based on an H index. Background technique [0002] 5G wireless network is expected to support 10Gbps peak data rate to support a larger number of users and various responsive applications. Ultra-density network is the key technology to solve high-speed data rate and ultra-high traffic in 5G wireless network. 5G ultra-density network has received more and more attention in recent years. For 5G ultra-dense networks, the deployment scheme of its micro base stations (MiBS) and accurate location information of devices are crucial for 5G applications such as intelligent transportation and ecological monitoring. However, the existing distributed node positioning methods do not consider the optimal selection method of anchor nodes when the distribution of high-density nodes is large, that is to say, when the numbe...
