Abstract

An object of the present application is to provide an optimized method and apparatus for spectrum allocation. The method comprises: determining a link capacity on a frequency band by determining a signal-to-interference-to-noise ratio of a link operating on the frequency band in a wireless network according to the signal-to-interference-to-noise ratio and a successful decoding threshold; determining a maximum maintainable data rate of the link according to a transmission opportunity of the link and a link capacity on the frequency band; determining an end-to-end throughput of the data stream according to a maximum sustainable data rate to determine a network throughput of the wireless network; determining a spectrum utilization rate of the wireless network according to a spectrum allocation situation of links in the wireless network; constructing a multi-objective spectrum allocation problem according to spectrum utilization and network throughput, and optimizing the multi-objective spectrum allocation problem by non-dominated sorting genetic algorithm. Maximum allowable network throughput can be achieved and spectrum efficiency can be improved.

Description

technical field [0001] The present application relates to the field of communication networks, and in particular to a method and device for optimizing frequency spectrum allocation. Background technique [0002] The Internet of Things is a global network of independently addressable interconnected devices based on standard communication protocols, which allows people to connect with anyone and any device anytime, anywhere, and use links, networks and services reasonably. In a network, all devices must exchange information, and in most cases do so wirelessly. Therefore, the rapid increase in the number of devices in the Internet of Things will naturally increase the demand for spectrum resources, and the rapid development of the Internet of Things has more urgent needs for the scarce spectrum resources in wireless communication networks. Generally, most of the spectrum has been allocated to specific radio services, i.e. these services operate within designated frequency band...
