空天地网络具有覆盖范围大、吞吐量高、弹性强等优点.该文针对大量用户并发接入、网络负载不均衡所引发的网络拥塞、服务质量恶化等问题,提出一种面向密集场景的资源分配算法.首先以用户需求为中心,根据不同类型用户任务的偏好来构建用户效用函数,然后基于匹配博弈的网络选择算法和结合对偶上升法的功率控制算法来实现负载均衡,优化资源分配方案.实验表明,相较于传统策略,所提策略整体用户接入率至少提高35%,时延和吞吐量方面性能提升超过50%;在密集场景下,能更有效地均衡负载,提升网络性能.
Resource Allocation Algorithm of Space-Air-Ground Integrated Network for Dense Scenarios
Space-air-ground integrated network has the advantages of extensive coverage,high throughput,and strong elasticity.A resource allocation algorithm for dense scenarios is proposed to solve the problems of network congestion and deterioration of service quality caused by concurrent access of many users and network load imbalance.Firstly,the user utility function is constructed based on the user demand and the preferences of different types of user tasks.Then,load balancing is realized based on the matching game network selection algorithm and the power control algorithm combined with the dual ascending method,and the resource allocation scheme is optimized.Experimental results show that compared with the traditional strategy,the proposed strategy increases the overall user access rate by at least 35%,and improves the performance of delay and throughput by more than 50%.Load balancing is more effective in dense scenarios and network performance is improved.
