La sección de Ingenieria de las Telecomunicaciones propone la adquisición de un rack de computo de alta performance para cubrir las siguientes necesidades: ¿ Implementar/migrar los servicios internos de la seccion, incluyendo los servidores de autenticacion, servidor zimbra, servidor del blog, etc. ¿ Implementar la infraestructura de soporte a nuestros grupos de investigacion: tales como repositorios digitales, servidor NFS, maquinas virtuales para procesamiento. ¿ Implementar un laboratorio de redes virtualizado que permita extender nuestra oferta academica a escenarios multi-marca mas complejos, y a Tecnologias Cloud Computing/Cloud Networking/NFV, recobrando nuestro liderazgo en estos temas. El hardware fue adquirido el 2018 y desde esa fecha el GIRA se ha hecho cargo del equipo, desarrollando el orquestador VNRT primero, y su segunda version (HAST) que ha permitido que esta infraestructura no solo de soporte a los proyectos de cloud computing del grupo sino que permita la virtualizacion de labotatorios de la seccion tanto para cursos de pregrado como para actividades de formacion continua (cursos de la academia Fortinet como de la Diplomatura de tecnologias de Cloud Computing).

An international collaboration effort with a commercial equipage vendor (NEC Japan) designing architecture and algorithms for cross layer resource allocation, with emphasis on energy-efficient multi-terabit networking and on Software Defined Networking (SDN). Funding level US$ 600K/year. Project still continues at Raytheon BBN technologies (3rd year) with a different PI.

A multi-million dollars DARPA project aimed at providing global high-capacity fiber-optic core services with unprecedented speed, agility, and survivability. I led multi-disciplinary consortium members in the design of a centralized but scalable architecture for unified control of multi-vendor multi-domain devices. I was also personally responsible for the design of the agile, technology-agnostic, and highly efficient cross-layer resource allocator (CRA) module that reconfigures the network resources (IP routers, OTN switches, ROADMs, etc.) to efficiently satisfy diverse demands with different QoS, call setup, and protection requirements as well as diverse timescales and blocking probability targets. The CRA is responsible ¿ among other things -- for working path selection, share protection computation, resource assignment and equipment configuration.

International Technology Alliance (ITA), an US ARL and UK MoD led consortium of government, academy, and industry to perform joint research in network centric systems. Performing fundamental research on network science. Within this multi-million dollar project, I led two small projects (roughly US$100K each) developing closed-form expressions for the capacity of OSA-enabled ad hoc networks, and a universal mobility model framework (UMMF) to be applied to the study of ad hoc networks.

PIRANA is a multi-million dollar (over $40 million over 4 years) DARPA STO-sponsored research project part of the Wireless Network After Next (WNAN) Program. Through this program, BBN is developing a new networking waveform and inexpensive radio which takes combines multiple new technologies to create scalable, adaptive, ad hoc networks which meet the challenges of tomorrow¿s soldier missions. The low cost WNaN system provides a robust mobile ad hoc network (MANET) with dynamic spectrum access (DSA), disruption tolerant networking (DTN), and multiple cooperative transceivers on a compact, hand-held platform. As a result of the network being enabled by these highly innovative capabilities, WNaN allows operation in dense signal environments with cell-phone quality voice without dropping calls, facilitates mission command through the ability to easily set up to 128 call groups, and maintains situational awareness (SA) even when communications are interrupted. Because the WNaN software is delivered on low cost, commercially available components, WNaN radios can enable soldiers at every operational level to have a reliable communications device. I was responsible for designing the enhanced routing algorithm (E-HSLS) able to scale up to one million nodes.

I was the Principal Investigator for the BBN tasks in the Army Research Office (ARO) ¿Stochastic Optimal Control Algorithms and Next Generation Technologies for Dynamic Resource Allocation in Mobile Communications Networks¿ project, for which BBN was a subcontractor to Scientific Systems Company, Inc (SSCI). We formulated a joint routing, time and frequency scheduling problem under dynamic spectrum access rules and power constraints. We modeled real-life constraints and dependencies (e.g. power spill from transmitter to receiver) within a finite-horizon optimal control framework. The resulting integer-linear programming (ILP) formulation was then used to analyze the behavior of the system under small-size instances. SSCI also investigated the Lyapunov stability of the system.

neXt Generation (XG) communication was DARPA name for dynamic/opportunistic spectrum access. Under XG, a radio would sense the medium and if no primary user was present it will access the channel, following the contraints the regulatory constraints specified in a machine-readable policy language. X-MAC was a $2.2M DARPA ATO research project, developing an architecture and protocol set for XG communication. I led the MAC algorithm design, supervised its implementation in an OPNET-based simulation testbed, and analyzed its performance. I participated in the development of the architecture and the definition of the radio's "fundamental behaviors" (i.e., the functions/primitives all XG radios should implement). Only radios that abide to these fundamental behaviors could be accredited.
