Embodiment Construction

[0043] The present invention aims at the geographic location problem of the online measurement node of the wireless network, and provides a method for selecting the online measurement node of the wireless network on the premise of satisfying the detection probability required by the network, which reduces the computational complexity and the transmission cost of the measurement information.

[0044] To achieve the above object, the technical scheme of the present invention is as follows:

[0045] In the first step, the nodes of the wireless network are given the functions of measurement control node, measurement data processing node, measurement data collection and transmission function, and form an online measurement function for the measured node;

[0046] In the second step, the wireless measurement control node uses the network management system to start the online measurement task;

[0047] In the third step, the measurement control node divides the ellipse measurement ar...

Abstract

The invention provides an online measurement node selection method for a wireless network. The method comprises that: a measurement control node starts a network management system to configure a measured node and a measurement data processing node; the measured node and the measurement data processing data transmit communication covered radius and position information to the measurement control node; other network nodes transmit position information to the measurement control node; the measurement control node divides an ellipsometry region according to an online measurement task, the position information of the measurement node, the communication covered radius and position information of the measured node and the measurement data processing node; and the measurement control node calculates the position of the measurement node with the best performance metric, and selects an actual measurement node which is closest to the measurement node with the best performance metric. The method can reduce the cost for transmitting a measurement report on the premise of meeting the detection probability required by the wireless network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for selecting an online measurement node of a wireless network. Background technique [0002] Due to the time-varying nature of its network nodes and wireless links, wireless networks need to be dynamically adjusted. Therefore, resource optimization technologies such as topology control and dynamic spectrum allocation are introduced to provide large-capacity and high-reliability wireless transmission capabilities. However, the realization of these key technologies depends on the effective acquisition of information such as the working status of the wireless network and the occupation of wireless resources, as well as wireless network measurement and cognitive technologies. [0003] The 802.11h and 802.11k standards issued by the IEEE (Institute of Electrical and Electronics Engineers) working group describe the basic measurements of wireless networks in de...
