Best Papers

Ricard Vilalta, Raül Muñoz, Ramon Casellas and Ricardo Martínez, researchers at CTTC, have been awarded with the ICIN 2013 Best Paper for their paper on: Manifiesto of Edge ICT Fabril.

The paper presents the following: Technology advances are making available huge amounts of processing, storage, networking capabilities at the edge (i.e., up to End -Users premises) of current networks. It is argued that these trends, coupled with new emerging paradigms such as Software Defined Networks, will impact deeply the evolution future networks, allowing to design highly flexible architectures at the edge capable of creating a galaxy of new ICTbusiness opportunities. This paper presents this vision by proposing a so-called “manifesto of edge ICT fabric”: the sheer number of nodes, devices and systems being deployed at the edge, up to Users’ premises, will create an ICT fabric offering an enormous processing and storage power. Using this ICT fabric, which is closer to the Users, for executing network functions and services will bring several advantages, both in term of improved performance and cost savings (e.g., determined by the removal of middle-boxes). It is argued that incentives, cooperation and competition at the edge will boost the long-term value of networks: like in ecosystems, where evolution select the winning species, winning services will succeed, grow, and promote further investments, while losing ideas will fade away.

Jesus Alonso-Zárate and Christos Verikoukis, researchers at CTTC, have been awarded with the 2013 EURASIP paper award for their paper on: Persistent RCSMA: A MAC protocol for a distributed cooperative ARQ scheme in wireless networks, published in EURASIP Journal on Advances in Signal Processing, Special Issue on Wireless Cooperative Networks, Volume 2008.

The paper presents the persistent relay carrier sensing multiple access (PRCSMA) protocol as a novel medium access control (MAC) protocol that allows for the execution of a distributed cooperative automatic retransmission request (ARQ) scheme in IEEE 802.11 wireless networks. The underlying idea of the PRCSMA protocol is to modify the basic rules of the IEEE 802.11 MAC protocol to execute a distributed cooperative ARQ scheme in wireless networks in order to enhance their performance and to extend coverage. A closed formulation of the distributed cooperative ARQ average packet transmission delay in a saturated network is derived in the paper. The analytical equations are then used to evaluate the performance of the protocol under different network configurations. Both the accuracy of the analysis and the performance evaluation of the protocol are supported and validated through computer simulations.

CTTC elected as a Steering Board Member of the European Technology Platform Net!works

The election of the members of the Steering Board (SB) of the Net!Works ETP for the period 2014-15 took place during the 9th General Assembly of Net!Works on 29 October 2013 in Brussels. Voting is organized on a stakeholder basis around the so-called (large) Industry, Small and Medium Enterprises (SME) and Research domains, the latter including representatives both from Universities and R&D centers. Net!works’ Steering Board gathers all the key players in the telecommunications arena (equipment manufacturers, mobile operators, service developers, research centers, etc.).

In the aforementioned General Assembly, CTTC’s R&D Program Director, Dr. Carles Antón-Haro, was elected as an SB member for the Research Domain. Competition was particularly high in this occasion since the number of seats available for the Research Domain was six and the total number of candidates for that domain close to 25 from all over Europe. Dr. Carles Antón-Haro has been a member of Net!works’ Steering Board since 2009.

CTTC researcher awarded as a IEEE ComSoc Distinguished Lecturer

Mischa Dohler, Senior Researcher of the  CTTC has been honored as a distinguished lecturer of IEEE ComSoc 2012 and 2013. The IEEE Communications Society is a diverse network of industry professionals with a common interest in the promotion of all communications technologies.

Each society of the IEEE nominates a few of such lecturers every year. Given an IEEE membership of 400k members, the penetration to-date is some 0.025%. Dr. Mischa Dohler is thus one of the very few Europeans and only Spain-based ComSoc Distinguished Lecturer globally. The international selection committee had based their decisions on these evaluation criteria: 1) strength of the references in the nominations; 2) oratorical reputation of candidates; and 3) expert subject matter of candidates.
