主讲简介:Professor Geyong Min is a Chair in High Performance Computing and Networking and the Academic Lead of Computer Science in the College of Engineering, Mathematics and Physical Sciences at the University of Exeter, UK. His recent research has been supported by European Horizon-2020, FP6/FP7, UK EPSRC, Royal Society, Royal Academy of Engineering, and industrial partners including British Telecom, Huawei Technologies, IBM, INMARSAT, Motorola, and InforSense Ltd. He has published more than 200 research papers in leading international journals including IEEE/ACM Transactions on Networking, IEEE Journal on Selected Areas in Communications, IEEE Transactions on Computers, IEEE Transactions on Parallel and Distributed Systems, IEEE Transactions on Communications, and IEEE Transactions on Wireless Communications, and at reputable international conferences, such as SIGCOMM-IMC, INFOCOM, and ICDCS. He is an Associated Editor of several international journals, e.g., IEEE Transactions on Computers, and IEEE Transactions on Cloud Computing. He served as the General Chair/Program Chair of a number of international conferences in the area of Information and Communications Technologies. 研讨特长:无线多媒体网络。

主讲内容:随着先辈无线通讯技能的疾速创新,过来几年,挪动多媒体使用(比方,及时挪动视频、3D视频流、VoIP、挪动电视等)的开展迅猛。这些内容丰厚、资源匮乏的多媒体使用顺序发生了庞大的流量形式,并对效劳质量(QoS)有很高的要求。但是,无线通讯的固有特性,如带宽稀缺、传输范畴有限、信道易堕落、接入技能异类等,招致可用通讯资源的高度动向性,给多媒体使用带来了宏大的应战。本次讲座起首引见异质随机模子来捕获多媒体使用的交通特性(如突发性、自类似性和大滞后相干)。同时,在此根底上,论述一种混淆业务调理机制的功能剖析模子,该混淆业务调理机制以分层的方法集成了根本的调理方案,是无线多媒体网络中一种很有出路的QoS区分战略。经过对剖析后果与实践条理在实践多媒体使用中的仿真实行后果的比拟验证模子的精确性。然后将该模子用作无线多媒体网络资源分派和办理的一种经济无效的功能优化东西。最初,提出和讨论相干的新兴题目和将来偏向。
