Resource Allocation And Optimization Of Aerial Collaborative Access Networks For Smart Villages

In recent years,our country has put a rural revitalization strategy on the agenda,and smart villages have emerged.The construction of smart villages includes an infrastructure layer and a smart application layer.Both layers of construction put forward higher requirements on the network and require a new network architecture.The aerial access network is expected to be suitable for future smart villages,but the network still faces problems such as low energy efficiency,time delay and high energy consumption.This article proposes an aerial collaborative access network built by unmanned aerial vehicle and high-altitude platforms for smart villages,and optimizes the network to improve network performance.The main work of this paper is as follows:(1)The problem of maximizing energy efficiency in the aerial collaborative access network is studied.With the overall goal of maximizing energy efficiency,the ground-toaerial uplink channel model is established under the limit of ensuring the minimum transmission rate of ground users,and a power allocation scheme based on immune optimization algorithm is designed.The simulation results show that the proposed algorithm can be significantly improve system energy efficiency.(2)The problem of resource allocation in the aerial collaborative access network is studied.First,the system model,channel model,transmission model and calculation model are established.Then,with the goal of minimizing delay and energy consumption,the optimization based on location is designed.Method,the Hungarian algorithm is used to find the best ground sensor,aerial access point and high-altitude platform connection and layout relationship,and then the Lagrangian duality method is used to solve the best power distribution plan.The simulation results show that this method is effective Improve network performance.
