Abstract
The convergence between Telecommunication and Computer Communication have lead to powerful multimedia
communication frameworks that include the use of new techniques (like P2P) to implement the Real Time Multimedia services.
On the other hand current mobile telephones present powerful hardware architecture, full operating system and rich media
interfaces for user requiring a good Quality of Experience (QoE). The impact of streaming video technology in modern multimedia
communication networks is crucial. In the coming years its impact could be even greater due to the continuous evolution of Internet,
multimedia services and wireless access networks (and associated mobile telephones).
Moreover, the Internet of People will demand new multimedia interfaces on mobile telephones
focused in the people; the Internet of things will make the mobile telephones (and probably MP3 and MP4 gadgets)
include wireless sensors to enrich the multimedia communication among people; The Internet of the ideas will enhance
the Wireless Spontaneous Networks as the preferred medium for people to express their videos and audios of opinion using mobile telephones.
Video streaming has been research a lot in the last recent years. But still it must be improved to be efficiently implemented in heterogeneous networks.
In this context, an important fact is that all wireless technologies suffer the same problem: the mobile telephones suddenly loss their coverage leading to sporadic and impossible to predict service disruptions. These service disruptions provoke a huge loss of streaming performance, QoE and Quality of Service (QoS). For these reasons the impact of video streaming on next Internet multimedia services could be slowed by its inefficiencies in presence of disruptions in Internet wireless access networks.
In this keynote Speech we will analyze the problems of service disruptions and analyze different solutions.
The focus of the current keynote Speech will include more specifically the following topics:
- Analysis of actual and coming streaming based multimedia services. (10% of time)
- Review state of the art in mobile telephone programming software and operating systems for multimedia services. (10% of time)
- Review of actual streaming mobile Clients and Servers for mobile telephones and their problems. (10%)
- Analysis of general parameters that influence service disruptions in wireless access networks. (30%)
- Analysis of a particular cross-platform solution to service disruptions and further required research. (40%)
Biographical sketch
Dr. Elsa Maria Macias Lopez is Associate Professor of Telecommunications, University of Las Palmas de Gran Canaria, Spain. He is the Head of the International Relations of the Technical University School Telecommunications of at the University of Las Palmas de Gran Canaria, Spain, from 2005-. He is an expert reviewer of research projects for the Spanish ministries. He in 1997 started working network computing and heterogeneous computing as a member of the Concurrency and Architecture Group (GAC). Her research interests are in parallel and heterogeneous distributed computing, multimedia collaborative frameworks, and wireless and sensor networks. Her current research efforts have focused on the management of wireless channel disconnections to prevent abrupt endings of multimedia applications.
Dr. Alvaro Suarez Sarmiento is Full Professor of Telecommunications, University of Las Palmas de Gran Canaria, Spain. He was the Head of the Telematic Engineering Department at the University of Las Palmas de Gran Canaria, Spain, from 1998-2009. He is an expert reviewer of research projects for the Spanish ministries. He in 1990 started working in systolic computing in the Technical University of Catalonia. Then he turned his attention to network computing and heterogeneous computing in 1994 when he returned to the University of Las Palmas de Gran Canaria where he founded the Concurrency and Architecture Group (GAC). His research interests are in Web computing and communications, multimedia collaborative frameworks, and wireless and sensor networks. His current research efforts have focused on the management of wireless channel disconnections to prevent abrupt endings of multimedia applications. He is author and co-author of several papers in the above topics. He has directed and participated in several European, Spanish, Regional and Enterprises research projects. Professor Suarez teaches telecommunications at the beginning, advanced, and graduate levels, and advises graduate and PhD theses in the area of wireless communications and Web computing. He also has lectured in Ca Foscari University (Italy), several invited talks in Spanish universities and governmental Institutions, and several tutorials at: the IMECS 2006, in Hong Kong; MSWIM, 2006, Torremolinos, IWWN, London, 2007.
