摘要:

移动社交网络平台的多元化发展与推广,使得移动用户对数据传输的需求呈爆发式增长趋势,并对匮乏的频谱资源及高负荷基站的管理提出了新挑战。为了解决这些问题,将分布式缓存系统引入无线协作网络中,鼓励移动用户间协作缓存热门内容,以实现用户间低能耗、高可靠、低时延的内容共享,同时为基站和回程链路减负。分析了无线分布式缓存系统中无线资源管理所面临的机遇和挑战,针对频谱高效、能量高效及安全传输等关键问题,围绕图论和匹配理论对无线资源管理方法展开了讨论和总结。此外,讨论和分析了挖掘和利用社交信息有效提升无线资源效率的可行性,同时对社会学和无线网络领域的交叉研究进行了展望。

Abstract:

The diversified development and popularization of the mobile social network platform has made the demand of data transmission for mobile users show an explosive growth trend,and put forward new challenges to the lack of spectrum resources and the management of high load base stations. To solve such problems, the distributed caching system was introduced into the wireless collaboration network by allowing users to cache popular content items cooperatively, for effective content sharing among users with low energy consumption,high reliability and low latency,while offloading base station and backhaul data traffic. Firstly, the challenges and problems for wireless resource allocation in wireless distributed caching system were analyzed.Graph and matching theory based on methodologies were discussed to solve the resource management problems in terms of energy efficiency,spectral efficiency and secure transmission respectively.In addition,the feasibility of mining and using social information to improve the efficiency of wireless resources was discussed and analyzed, which provided a brief outlook on future interdisciplinary research between social science and wireless network.

Key words: wireless resource management, distributed caching system, social network
