Example Embodiment

[0022] Example one

[0023] figure 1 This is a flowchart of a method for increasing the selection rate of a wireless network relay provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method mainly includes the following steps:

[0024] Step 11. Determine the number of primary selected sectors according to the total number of sectors in the network.

[0025] The embodiment of the present invention counts the total number of sectors in the network in advance, and then determines the number of corresponding primary selected sectors. For example, it can be determined in an adaptive manner. From a geometric point of view, since the relays in the same direction at the transmitting end and the receiving end have a small relay link distance, the cumulative loss of the channel is small. Therefore, the primary sector is selected in the same direction as the receiving end. . Exemplarily, it can be known from simulation statistics of the distribution law of the ...

Abstract

The invention discloses a method and system for increasing the relay selection speed in a wireless network. The method comprises the following steps: the number of primary sectors is determined according to the sum of sectors in the network; the sector number of an interrupted link receiving terminal in a transmitting terminal is acquired according to geographical location information, and the actual primary sector corresponding to the sector number is determined according to the number of the primary sectors; according to a channel model of the wireless network, an optimal candidate relay in the actual primary sector is determined. By adopting the method and system for increasing the relay selection speed in the wireless network, the relay selection speed is increased greatly.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a method and system for improving the relay selection rate of a wireless network. ? Background technique [0002] In recent years, the wireless communication technology that realizes the transmission rate of Gbit / s or even several Gbit / s has become a new focus of forward-looking research in the field of wireless communication, and 60G wireless millimeter wave technology is one of the research directions that has attracted wide attention. [0003] The characteristics of high frequency and short wavelength lead to extremely poor penetration of directional 60G wireless millimeter wave diffraction, and obstacles such as walls will greatly attenuate millimeter waves, resulting in failure of direct link communication. In order to avoid obstacles directly blocking 60G wireless millimeter wave communication, it is necessary to use relays to establish multi-hop links and complete commu...
