【摘要】：D2D(Device-to-Device)通信作為蜂窩網(wǎng)中的一種新型的通信方式,因其在提高傳輸速率和改善能效性能等方面的無可比擬的優(yōu)勢,受到人們越來越多的關(guān)注。但是,D2D通信技術(shù)在帶來令人無法抗拒的優(yōu)勢的同時,亦會產(chǎn)生棘手的干擾問題。鑒于此,本文從降低干擾的不利影響、提高網(wǎng)絡(luò)能效性的角度出發(fā),綜合蜂窩用戶共享資源的主觀性和客觀性因素,探討了無線資源共享機(jī)制的設(shè)計問題,即聯(lián)合模式選擇和鏈路資源分配。首先,分析了D2D通信中的兩種通信模式下用戶的能量有效性。其次,將能量有效的無線資源共享問題建模為效用不可轉(zhuǎn)移聯(lián)盟形成博弈,分析了博弈性質(zhì),并基于合并-拆分準(zhǔn)則和帕累托偏好關(guān)系提出一種分布式算法,依此確定無線資源共享策略。最后給出并分析了數(shù)值仿真結(jié)果,以驗(yàn)證所提機(jī)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.
