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. 研究专长:无线多媒体收集。

主讲内容:跟着先辈无线通讯技能的疾速立异,曩昔几年,挪动多媒体应用(例如,实时挪动视频、3D视频流、VoIP、挪动电视等)的睁开迅猛。这些内容丰富、资本匮乏的多媒体应用程序发生了复杂的流量情势,并对效劳品德(QoS)有很高的请求。然而,无线通讯的固有特性,如带宽稀缺、传输规模无穷、信道易出错、接入技能异类等,导致可用通讯资本的高度静态性,给多媒体应用带来了弘大的挑衅。本次讲座首先介绍异质随机模子来捕捉多媒体应用的交通特性(如突发性、自相似性和大滞后相干)。同时,在此根底上,阐述一种混合业务调剂机制的机能阐发模子,该混合业务调剂机制以分层的办法集成为了基本的调剂计划,是无线多媒体收会合一种很有前途的QoS区分战略。颠末过程对阐发结果与实际体系在实际多媒体应用中的仿真试验结果的比较验证模子的精确性。然后将该模子用作无线多媒体收集资本分派和解决的一种经济有用的机能优化对象。末了,提出和讨论相干的新兴成就和未来偏向。
