D2D联合模式选择与资源分配的研究
Research on D2D Joint Mode Selection and Resource Allocation
摘要
Abstract
[Objective]In the case of relatively scarce communication resources,the D2D direct reuse technology of cellular network resources may cause numerous technical problems such as inter-ference management,communication mode selection,and resource allocation.[Methods]This paper studies the scheme of the combination of mode selection,channel distribution,and power control.Because optimizing the combination scheme is an NP-hard problem,this paper divides the optimization problem into two sub-problems:one is to select an appropriate communication mode and allocate reasonable channel resources for each D2D user,and the other is to opti-mize the power for D2D users and honeycomb users by the improved gray wolf algorithm.The goal of this approach is to improve the overall system throughput and reduce the interference.[Results]The experimental results in different scenarios show that this approach can effective-ly reduce the interference and improve the system throughput.The improved gray wolf algo-rithm has increased the average throughput by about 4%for this solution.[Limitations]The Gray Wolf Optimization Algorithm is continuously evolving and introduces certain limitations.[Conclusions]The subsequent work will continue to explore and consider the network status and the user mobility,improving both performance and throughput of the system.关键词
