Embodiment Construction

[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0065] refer to figure 1 , a method for maximizing the throughput of energy-intensive wireless relay networks based on the asynchronous dominant actor-critic algorithm, in other words, the maximization of system benefits by end-to-end throughput maximization is achieved through joint time scheduling and power allocation. The present invention is based on an energy-collecting wireless relay network system (such as figure 1 shown). In the energy-intensive wireless relay network system, the time scheduling and power allocation are optimized through the asynchronous dominant actor-critic algorithm to achieve the maximum transmission rate. The invention proposes a renewable energy optimization method for maximizing throughput for the time scheduling and power control problems in energy-collecting wireless relay networks under the condition of limited data cache ...

Abstract

A method for maximizing throughput of a centralized radio relay network based on an asynchronous dominant actor critic algorithm comprises the following steps: 1) maximizing throughput in the centralized radio relay network through regenerative energy optimization management, wherein, the optimization problem is described as a multivariable optimization problem; 2) decomposing the problem P1 intotwo parts of optimization: Power sub-optimization and time slot sub-optimization, i. e. Optimizing variables pi and (img file = 'DDA000173584527000011. TIF' wi= '48' he= '66' / ) by asynchronous dominant actor critic algorithm to obtain optimal ri. A method for maximizing system efficiency with maximum throughput in a centralized radio relay network by combining time scheduling and power allocationis provided.

Description

technical field [0001] The invention relates to the technical field of energy-collecting wireless relay networks, in particular to an energy-collecting wireless relay network throughput maximization method based on an asynchronous dominant actor-critic algorithm. Background technique [0002] Mobile data traffic has been growing exponentially due to the proliferation of wireless devices and emerging multimedia services. Due to channel losses such as path loss, shadowing, and small-scale fading, more and more indoor and edge users may experience low-quality service performance. To overcome this obstacle, relay-assisted access technology has been proposed as a valuable solution to exploit energy efficiency and spatial diversity to improve user service quality indoors and at the cell edge. The relay base station will serve as a relay station for communication between edge users and macro cell base stations. [0003] However, the energy consumption generated by densely deployi...
