The invention discloses a communication resource and computing resource joint allocation method in unmanned aerial vehicle auxiliary emergency communication. The method comprises the following steps: constructing an unmanned aerial vehicle auxiliary emergency network platform; acquiring state information based on an unmanned aerial vehicle auxiliary emergency network platform, and constructing first, second and third queuing models according to the state information; calculating a first queuing time delay according to the first queuing model, calculating a second queuing time delay according to the second queuing model, and calculating a third queuing time delay according to the third queuing model; constructing a weighted sum function model according to the first queuing time delay, the second queuing time delay and the third queuing time delay; decoupling the weighted sum function model into an air base station and ground user association strategy sub-problem, an air base station and ground base station task unloading strategy sub-problem and an air base station trajectory planning strategy sub-problem by using a Lyapunov stochastic optimization method; and solving each sub-problem to obtain a corresponding air base station and ground user association strategy, a track planning strategy and a task unloading strategy. According to the invention, the communication task calculation time is reduced.

    本发明公开了一种无人机辅助应急通信中通信资源和计算资源联合分配方法,包括:构建无人机辅助应急网络平台;基于无人机辅助应急网络平台获取状态信息,根据状态信息构建第一、第二、第三排队模型;根据第一排队模型计算第一排队延时,根据第二排队模型计算第二排队时延,根据第三排队模型计算第三排队时延;根据第一、第二和第三排队时延构建加权和函数模型;利用李雅普诺夫随机优化方法将加权和函数模型解耦为空中基站与地面用户关联策略子问题、空中基站与地面基站任务卸载策略子问题、空中基站的轨迹规划策略子问题,针对每个子问题求解得到对应的空中基站与地面用户关联策略、轨迹规划策略、任务卸载策略。本发明降低了通信任务计算时间。
