Description:
Nowadays, the whole world of telecommunications and information communities is facing a more and more serious challenge, namely on one side the transmitted multimedia-rich data are exploding at an astonishing speed and on the other side the total energy consumption by the communication and networking devices and the relevant global CO2 emission are increasing terribly. Recently it has been pointed out that energy costs account for as much as half of a mobile telecommunication operator’s operating expenses. In general the traffic of Internet is constantly growing by 60 percent per year and it is definitely a nightmare scenery if the power consumption of Internet would increase by the same amount per year. Therefore, telecommunications applications can have a direct, tangible impact on lowering greenhouse gas emissions, power consumption, and achieve efficient recycling of equipment waste. Moreover, to find multimedia, broadband and intelligent radio networking solutions that can greatly improve energy-efficiency and resource-efficiency (Green Communications) is not only benefit for the global environment but also makes commercial sense for telecommunication operators supporting sustainable and profitable business.
Within the framework of “Green Communications”, a number of paradigm-shifting technical approaches can be expected, including but not limited to energy-efficient network architecture & protocols, energy-efficient home networking, energy-efficient broadband access, energy-efficient wireless transmission techniques, cross-layer optimization methods, and opportunistic spectrum sharing without causing harmful interference pollution (i.e. Green Spectrum).
This panel is aimed to bring together the key-players coming from the industry, academy, and government bodies with various backgrounds and expertise, while targeting for deeply exploring various significant aspects of “Green Communications” and their potentially enabling technologies.

4. Attending Doctorate Thesis Defense at the University of Twente, The Netherlands (February 24 - 27, 2009)
Abstract:
Wireless ad-hoc networks enable communications between a number of transceivers, without a fixed infrastructure. Typically, information is passed from source to destination via a number of relays. For collaborative ad-hoc networks, the information is passed over several relay nodes in parallel, thus improving the reliability and increasing energy efficiency. For such networks, the traditional design paradigm of separately optimizing physical layer, MAC layer, and network layer, leads to suboptimum results. Instead, we have to employ a cross-layer design, taking into account the impact of the layers onto one another. After a general introduction to this principle, the talk will concentrate on case studies of cross-layer optimization in collaborative ad-hoc networks. We consider a network where nodes employ fountain codes to ensure reliable transmission, and show how routing in such networks differs from conventional shortest-path routing. A summary and conclusions wrap up this talk.

Seminar Title: "Cross-layer Optimization of Future Wireless Collaborative Ad-hoc Networks"
Photo1: The Doctorate Defense & Ceremony at the University of Twente, The Netherlands.
During the period of Feb. 24 to Feb. 27, 2009, I have visited the University of Twente, the Netherlands, and have taken part in the doctorate defense and ceremony of Dr. Qiwei Zhang (Doctorate Thesis: "Cognitive Radio on a Reconfigurable MPSoC Platform", Supervisor: Prof. Gerard Smit), as an invited doctorate committee member.
I was so impressed by the traditional doctorate defense and ceremony that I experienced. At the celebration party after the doctorate ceremony, I was told that this kind of traditional events has lasted more than two hundred years within all the universities of the Netherlands, with its roots returning to the 18th century. In particular, please let me cite the following restrict but interesting official requirement of the University of Twente on the "ATTIRE" for the doctorate defense and ceremony, which can be clearly expressed by the above Photo 1.
"During the doctorate ceremony the chairmen, secretary, doctoral thesis supervisors and members of the doctorate committee wear the following, prescribed attire:
Professors: gown and cap. External professors are invited to wear their own gown and cap. The University of Twente also provides a limited number of gowns and caps for professors.
Non-professors: an appropriate suit in a dark colour (dark blue, black or dark grey)."
