Abstract

The invention relates to the field of Internet of Things, wireless communication and sensor networks. Specifically, the invention relates to a multi-relay wireless data transmission control method based on radio frequency signal energy supply. The method mainly comprises the following steps: 1) establishing a system model which is composed of a multi-antenna hybrid transmitter capable of transmitting signals and energy at the same time, a plurality of single-antenna relays capable of receiving information and energy, and a single-antenna receiver; 2) establishing a mathematic model with the PSprotocol and TS protocol according to the system model; and 3) optimizing a solution to a problem. A power distribution (PS) mode and a time switching (TS) mode are considered at the same time, meanwhile, the situation that a direct connection link from a transmitter to a receiver better conforms to the actual scene is considered, and the total throughput of the system is maximized.

Description

technical field [0001] The present invention relates to the fields of Internet of Things, wireless communication, and sensor network, and in particular, relates to a multi-relay wireless data transmission control method based on radio frequency signal power supply. Background technique [0002] As the number of various electronic devices will greatly increase, a large number of wireless communication devices are powered by batteries with limited capacity, and the maintenance cost and life cycle of the equipment depend largely on the battery, and the problem it brings is that it shortens the Equipment service life. The existing processing method is usually to directly discard the battery after it is depleted or to use a wired connection to supply energy. Although the cost of replacing a battery for a single device is not high, when the number of devices increases massively, direct processing will cause a lot of waste. And, because of the sheer volume, it becomes impractical ...
