Abstract

Integrated sensing and communication enhances the spectral efficiency by using shared resources, eliminating the need for separate bandwidth allocations. Unmanned aerial vehicle (UAVs) play a key role in this, offering mobility, flexibility, and extended coverage for serving multiple users, especially in scenarios like disaster response and environmental monitoring. This paper explores multiple UAVs with integrated sensing and communication capabilities, using the Age of Information (AoI) metric to optimize resource allocation for timely data transmission. We propose two algorithms, Variable Particle Swarm Optimization (VPSO) and Twin Variable Neighborhood Particle Swarm Optimization (TVPSO), to jointly optimize power, bandwidth, and UAV trajectories to minimize AoI. Numerical results show the effects of the sensing and communication power ratio, the number of UAVs and the number of users on AoI and energy consumption. Furthermore, TVPSO is shown to outperform other PSO variants and the Deep Q Networks (DQN)-based approach, offering faster convergence and superior performance.

通过综合传感与通信优化多无人机多用户系统，促进信息时代（AoI）分析

综合传感与通信通过使用共享资源提高了频谱效率，无需单独分配带宽。无人飞行器（UAV）在其中发挥了关键作用，它具有机动性、灵活性和扩展的覆盖范围，可为多个用户提供服务，特别是在灾难响应和环境监测等场景中。本文探讨了具有综合传感和通信能力的多架无人飞行器，利用信息时代（AoI）指标来优化资源分配，以便及时传输数据。我们提出了两种算法：可变粒子群优化（VPSO）和孪生可变邻域粒子群优化（TVPSO），以联合优化功率、带宽和无人机轨迹，从而最大限度地降低 AoI。数值结果显示了传感和通信功率比、无人机数量和用户数量对 AoI 和能耗的影响。此外，结果表明 TVPSO 优于其他 PSO 变体和基于深度 Q 网络（DQN）的方法，收敛速度更快，性能更优越。
