【摘要】：D2D(Device-to-Device)通信作为蜂窝网中的一种新型的通信方式,因其在提高传输速率和改善能效性能等方面的无可比拟的优势,受到人们越来越多的关注。但是,D2D通信技术在带来令人无法抗拒的优势的同时,亦会产生棘手的干扰问题。鉴于此,本文从降低干扰的不利影响、提高网络能效性的角度出发,综合蜂窝用户共享资源的主观性和客观性因素,探讨了无线资源共享机制的设计问题,即联合模式选择和链路资源分配。首先,分析了D2D通信中的两种通信模式下用户的能量有效性。其次,将能量有效的无线资源共享问题建模为效用不可转移联盟形成博弈,分析了博弈性质,并基于合并-拆分准则和帕累托偏好关系提出一种分布式算法,依此确定无线资源共享策略。最后给出并分析了数值仿真结果,以验证所提机制的可行性。
[Abstract]:As a new communication mode in cellular networks, D2D (Device-to-Device) communication has attracted more and more attention because of its unparalleled advantages in improving transmission rate and energy efficiency. However, D2D communication technology brings irresistible advantages as well as intractable interference problems. In view of this, this paper discusses the design of wireless resource sharing mechanism based on the subjective and objective factors of cellular users sharing resources from the view of reducing the adverse effects of interference and improving network energy efficiency. That is, joint mode selection and link resource allocation. Firstly, the energy efficiency of two communication modes in D2D communication is analyzed. Secondly, the energy-efficient wireless resource sharing problem is modeled as a utility non-transferable alliance to form a game. The properties of the game are analyzed, and a distributed algorithm is proposed based on the merge-split criterion and Pareto preference relationship. Based on this, the wireless resource sharing policy is determined. Finally, the numerical simulation results are given and analyzed to verify the feasibility of the proposed mechanism.
