The Third Symposium on Broadband Networks and Fast Internet (RELABIRA’2012) Paul Ghobril Antonine University, 40016 Baabda, Lebanon
Third Symposium on Broadband Networks and Fast Internet (RELABIRA’2012) has an identity resumed by coherent diversity. It covers a wide spectrum of technological topics related to Networks. Since its first edition in 2010, this symposium includes what we have called a non-technical although deeply scientific session. This non-technical session deals with a controversial subject related to the impact of Broadband Networks and Fast Internet on societal, economic, juridical and ecological scopes. This year, we have chosen to substitute this session by keynote speeches on “Sustainable development”;Moreover, we also had a technical session on Energy Efficient Networking directly related to this theme. In the first edition we stressed on Cybersecurity as a non-technical theme and we highlighted on privacy on the net, shortly before it became a hot topic in Lebanon. Moreover in the first edition also, we were the first to give technical details on the IMEWE submarine optical fiber cable which was in the last phases of its deployment. In the second edition, in addition to introducing network neutrality required from operators, we highlighted on the broadband infrastructure in Lebanon. With this third edition, the symposium gains a new dimension by the technical support of the Institute of Electrical and Electronics Engineers (IEEE), the world’s largest professional association for technologies that gives authors ultimate visibility and providesa guarantee on the published materials. This was the result of a perseverant work on previous editions and of setting up a qualified technical committee chaired by Mr Bernard Cousin from University of Rennes1 who worked hard with the help of Mrs Esther Le Rouzic from Orange Labs (network and carriers departement) and Mr Tijani Chahed from Telecom Sud-Paris, from the steering committee and the assistance of Mr Zaher Dawy, the chair of the Lebanese Chapter of IEEE Communications Society. High-profile keynote speakers gave talks on hot topics HE
related to green networking and green computing. Accepted high quality papers allowed us to compose an interesting program with variant themes and different sessions showing coherence and complementarities between accepted papers. I will make a quick review of the different sessions and I will highlight on some interesting snapshots. We had two interesting Keynote Speeches. In the first one, Mr. Marco Ajmone Marsan shared with us his experience with green networking in the framework of the FP7 Network of Excellence, TREND. After an overview of the project and under the Work Package 2 of TREND, he showed us how only two sleep modes are enough to benefit from sleep mode in cellular networks. The second Keynote Speaker Mr. Lanfranco Marasso gave an attractive talk on how to design a service-tocitizen application in an innovative way. The novel Liquid Radio concept was introduced by Mr. Rabie Kalash from Nokia Siemens Networks. In the first session on Optical Networks, papers were presented on Monitoring trail concept, power fairness with adaptive light splitting, and improving Optical OFDM transmission performances in access networks. In the second session on Energy Efficient Networks, there were two talks; one onthe combination between cell zooming and sleep mode reducing energy consumption in cellular networks and the second on the benefit of improving energy efficiency for heterogeneous cellular networks using a new cooperative scheme associated to a game theory based power allocation scheme. The third session and last session of the first day treated the measurement and visualization technologies. A system of measuring the car speed using RFID tags was introduced and papers on visualization of eye diagram and edge detection were presented. The second day started with the motivating and tutorial presentation of Mr. Tijani Chahed on resource reallocation in 4G, where he showed how a user with bad radio conditions can help the one with good radio
conditions to enhance the global performance, i.e. the poor helping the rich. A Panel Discussion moderated by Mrs. Esther le Rouzic, Mr. Bernard Cousin and Mr. Tijani Chahed covered the topic of reducing power consumption in core, wireless and domestic networks and lead to a motivating discussion on flexible transparent optical networks, sleeping and waking up issues in mobile networks and green home networking. The 4th session on network security and system administration covered the security of Internet Multicast Transmission over Satellite Digital Video Broadcasting using a new encapsulation method that enables the switching of video packets by on-board satellite processor. The second presentation introduced the RTT parameter to improve detecting IP spoofing using the hop count filtering. The third presentation proposed an enhancement of key agreement protocol for LTE networks. Session 5 on mobile networks covered multicast protocols in adhoc networks, a presentation on Connection Admission Control mechanisms for a multi-channel and multi-user OFDMA-based WiMAX network and a presentation on the combination of uplink / downlink Signal to Interference and Noise Ratio measurement to enhance handover in LTE networks. The last session was about image processing technologies. The 4th Symposium on Broadband Networks and Fast Internet (RELABIRA 2013) will be held next year, at the Antonine University, on Tuesday and Wednesday May 28 and 29, 2013. At the end, I would like to thank each and every person who contributed to the success of this Symposium.
