Design And Implementation Of Optimized Transmission Simulation Platform For Energy Harvesting Relay Networks

At present,the energy consumption of the information and communication technology industry accounts for about 2%-6% of the global energy consumption,a large part of which comes from the wireless and mobile communications industries.With the development of wireless communication technologies,wireless communication devices have been widely used worldwide,and the number of base stations and the demand for power grid equipment have increased,resulting in the continuous growth of energy consumption in the communications industry.The energy harvesting wireless communication system studied in this paper is a green information and communication technology that combines green energy saving and wireless network.The energy harvesting wireless communication system is a self-sustained maintenance network for permanent communication equipment.It has the following three advantages:(1)The use of renewable energy instead of traditional grid equipment to provide power,fundamentally reduces energy consumption in the communications industry and responds to the call for green communication and energy-saving and emission reduction of the 13 th Five-Year Plan for Economic and Social Development of the People's Republic of China and the Information and Communication Industry Development Plan(2016-2020).(2)Get rid of the demand for grid power supply equipment,reduce the maintenance of grid power supply equipment,reduce labor costs,and improve the flexibility of network deployment.(3)Through the collection of energy from the surrounding environment to ensure the normal operation of the system,it breaks through the need for traditional battery power supply and greatly extends the service life of the system.This paper studies the energy harvesting relay networks and maximizes its long-term average throughput in Rayleigh fading channels.The main research contributions are listed as follows:Firstly,a greedy transmission strategy is developed based on a fixed threshold transmission strategy.The strategy is applied to a single-user multi-relay energy harvesting wireless communication system to dynamically select a long-term throughput-maximizing communication link.Secondly,the single-user multi-relay energy harvesting wireless communication system is extended to a multi-user multi-relay energy harvesting wireless communication system.This system uses the current time slot throughput of the greedy transmission strategy to maximize the performance index in the cost matrix of the Hungarian algorithm.It dynamically select a suitable relay distribution method for each user in the system to maximize its long-term average throughput.Finally,the greedy transmission strategy is applied to multi-relay energy harvesting wireless communication system,and a simulation platform for energy harvesting relay network optimization is designed.The simulation platform achieves relay selection visualization and verifies the effectiveness of greedy transmission strategies in improving long-term average throughput in relay selections.
