Optimization method of power distribution in accessing strategy of wireless relays of internet of things

Abstract

The invention provides an optimization method of power distribution in an accessing strategy of wireless relays of the internet of things. The method includes that in a local region of the internet of things, multiple nodes of the internet of things share a node in a wireless mode to be accessed to an application scenarios of a public cellular network, a model of attenuation channel capacity is adopted, the maximum channel capacity serves as the optimization method, and joint optimization of the power distribution is carried out on multiple access channels and multiple node relay channels in the scenarios. Due to the fact that a control device is relatively simple, the optimization method of the power distribution has the advantages of being rapid and brief, and requirements of the power optimization in the scenarios of the internet of things are met.

Description

technical field [0001] The invention belongs to the technical field of wireless networking in the Internet of Things, and relates to an optimization method for power distribution in a wireless relay access strategy of the Internet of Things. Background technique [0002] As one of the development directions of the next generation of information technology, the development of the Internet of Things will usher in great opportunities. At the same time, with the popularity of the third generation mobile communication network (hereinafter referred to as 3G), its high bandwidth and perfect coverage characteristics have become a good access network for the Internet of Things. Therefore, the combination of the Internet of Things and the public cellular network has positive significance for the development of the Internet of Things and the public cellular network. [0003] The Internet of Things is characterized by a large number of decentralized nodes (e.g. sensors, readers) and a ...

AI Technical Summary

Problems solved by technology

[0009] For such application scenarios of the Internet of Things, the first problem is that the existing power allocation optimization methods usually only optimize the multi-access channel and the relay channel separately, and lack a method for jointly optimizing these two types of channels. can affect the overall network performance in this scenario

The second problem is that the existing power allocation optimization scheme often requires a large number of iterative calculations, which is suitable for wireless networks with relatively fixed nodes, and requires high configuration of network management equipment.
