Andrés García Saavedra
Telematics Engineer, Ph.D.
I received my B.Sc. (2009) in Telecommunication Engineering from University of Cantabria (UNICAN), M.Sc. (2010) and Ph.D. (2013) in Telematics Engineering from University Carlos III of Madrid (UC3M). Currently, I work as a Research Fellow at the Hamilton Institute at National University of Ireland, Maynooth (NUIM).
My research interests lie in the application of fundamental mathematics to real-life computer communications systems, both wired and (specially) wireless; including resource allocation problems, energy efficiency, network coding, and design of network protocols and systems. I particularly enjoy building real prototypes and carrying out experimental performance evaluations of protocols and communication systems.

CARMEN 'CARrier grade MEsh Networks' (2005-2009).
European Project, FP7 Call 1, Objective 1.1: The Network of the Future.
CARMEN, CARrier grade MEsh Networks, studies and specifies a wireless mesh network supporting carrier grade triple-play services for mobile/fixed network operators. Future operator networks will be comprised of a common core network and several access networks, and the CARMEN access network will complement other access technologies by providing a low cost and fast deployment mesh network access technology. The project proposes the integration of heterogeneous wireless technologies in a multi-hop fashion to provide scalable and efficient ubiquitous quad-play carrier services. To address the integration complexity of heterogeneous radio technologies, CARMEN introduces a layer 2.5 located between the subnet layer and the routing layer (the abstract interface in the architecture figure below), in order to abstract technology specific issues into a common set of events and commands. Upper layers will use the abstract interface of layer 2.5 to dynamically adapt functions such as routing, mobility and monitoring. One relevant issue is that CARMEN will provide capacity handling algorithms to exploit specific features of the mesh networks such as the availability of multiple links between two peers (i.e. multipath) or the use of radio broadcast instead of unicast to alleviate the load of broadcast services (e.g. video) in the mesh network. CARMEN will focus on three planes: technology, message transfer, and self-configuration and management, to provide a complete solution for setting up and maintaining a cost-effective carrier grade wireless mesh access network.
