| 摘 要： | 研究网络资源调度优化问题,中继技术是发展网络的关键技术。传统的资源调度算法中,部分比例公平调度(PPF)与两跳比例公平调度(THPF)均有不足,PPF算法能获得较高的系统吞吐率,但不能保证用户的公平性,THPF算法则相反。为了解决系统同时获得吞吐率与用户公平性问题,根据THPF算法设计了一种基于最少好信道优先的两跳比例公平调度算法(S-THPF),通过优先给好信道较少的用户分配信道资源,从而保证尽可能多的用户获得最优的信道。仿真表明算法在提高系统吞吐率的同时能满足用户公平性要求。

| Abstract: | Relay technology is one of the key technologies for next generation networks,radio resource scheduling is very important in the relay system.Traditional resource scheduling algorithm has some shortcomings.Although the partial proportional fairness(PPF) algorithm is able to obtain a higher system throughput,it can not guarantee the user fairness.The two hop proportional fairness(THPF) algorithm is the opposite.In order to solve the contradiction between the system throughput and user fairness,based on the le... |
