ABSTRACT
With the growth of multimedia applications, dynamic evolution of networks makes the provision of Quality of Service (QoS) a complex process over heterogeneous networks with different protocols and different QoS domains. To establish end-to-end QoS, lots of efforts have been made to find ways to integrate QoS mapping solutions. However, in both academia and industries, to support effective end-to-end QoS for multimedia services over heterogeneous networks remains a challenge. This talk will discuss the challenges and possible solutions to this problem. It introduces system architectures and modeling for QoS support in mobile multimedia mesh networks; parametric model with network calculus theory for QoS class mapping between different QoS domains; QoS mapping schemes based on flow aggregate to mitigate the information loss problem due to different grained QoS class mapping, and to provide efficient network resources utilization by considering user’s Quality of Experience (QoE).

BIOGRAPHY
Yu-ning DONG received his B.E (1982), M.E degrees (1984) from Nanjing University of Posts & Telecommunications (China), Ph.D degree (1988) from Southeast University (China), all in Electrical Engineering, and M.Phil degree (1998) in Computer Science from The Queen's University of Belfast (UK). He is currently professor at Nanjing University of Posts and Telecommunications. During the academic year of 1992/1993, he was British Council postdoctoral fellow at Imperial College London, UK. From 1993 to 1995, he was visiting scientist at University of Texas, USA. After that he spent three years as research fellow at QUB and University of Birmingham, UK. He has contributed over 150 papers to IEEE and other technical journals and conference proceedings, and has served as guest editor and/or reviewer for a number of technical publications. His research interests include wireless networking, multimedia communications and Internet traffic identification.
