Problems solved by technology

[0006] For user area division, many studies only use the simplest threshold distance to divide the area, which is likely to lead to uneven division and the omission of individual users; the approximate algorithm of the UAV trajectory may not get the optimal solution; and a separate Considering the optimization of WET and WIT will also make the performance not maximized, so that the optimal solution cannot be obtained

Abstract

The invention provides an optimization method for a UAV-coordinated data-energy integrated network, including user area division, UAV hover point solution, UAV flight trajectory design, and optimization of downlink throughput and harvesting energy. The invention considers the user's battery capacity, the minimum throughput rate and the flight limitation of the UAV, and is closer to the actual constraints, and jointly optimizes the user's information and energy reception, while improving the downlink throughput rate, it also takes into account the user's The energy harvested by the device.

Description

technical field [0001] The invention relates to a mobile communication method, in particular to an optimization method for a data-energy integrated network coordinated by drones. Background technique [0002] As communication scenarios become more and more complex, traditional fixed base stations will no longer be suitable for complex communication systems in various scenarios, and UAVs (Unmanned Aerial Vehicle, UAV) are small in size, low in power consumption, convenient and powerful The advantages of battlefield survivability have become the subject of a recent wave of research. The communication network system coordinated by drones also provides a good solution for communication scenarios that cannot be covered by base stations. [0003] Energy Harvesting (EH) technology has great development prospects because it can provide stable energy for energy-constrained networks such as wireless sensor networks and prolong the network life cycle. The energy source of energy harv...
