Mobile communication via WiFi and cellular networks has revolutionized the data we have available at our fingertips. Even while traveling at high rates of speed, users are able to communicate on the Internet. As the majority of the world lives within urban environments that have strongly-connected cellular and WiFi networks, many people take for granted that they are always able to access information from the Internet. Gathering data from vehicles or devices traveling with vehicles through a vehicle-to-infrastructure (V2I) network allows many applications to be created that utilize data that has never before been available. I will discuss some of those applications and the manner in which I have implemented a V2I architecture in Alaska. In non-urban environments that lack the cellular and wireless infrastructure, vehicular ad-hoc networks (VANETs) can be used to communicate. Through multiple hops, vehicles in a disconnected environment can communicate on the Internet, though receiving data back gets complicated because of a potentially changed route based on the mobility of the vehicles. This talk will also discuss the design of a VANET and potential applications that can be used as a result.
Prof. Miller is an Associate Professor of Computer Engineering at the University of Alaska Anchorage. He earned a Ph.D. in Computer Science from the University of Southern California in 2007 with an emphasis in networking, algorithms, and software engineering, with a specific application in the field of Intelligent Transportation Systems. He is on the Executive Committee and Board of Governors for the IEEE Intelligent Transportation Systems Society and the IEEE Vehicular Technology Society. He is currently the Editor-in-Chief for the IEEE Intelligent Transportation Systems Magazine. His research interests include data gathering from vehicles in real-time through vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) architectures, utilizing distributed algorithms within those networks, and creating software simulators based on live and historical data for testing algorithms prior to large-scale deployment.

Tras la evaluación de la ITU-R y la reciente World Radio Conference de 2012, se ha dado por iniciado el lanzamiento tecnológico del estándar de cuarta generación LTE-Advanced. El seminario “El futuro de las comunicaciones móviles” pretende mostrar los puntos de mayor interés científico que marca el camino hacia las tecnologías hoy denominadas “Beyond 2020” que serán las de la 5G. Entre los aspectos más significativos se hablará de nuevos esquemas de acceso al medio, relay móvil, cooperación entre nodos, auto-organización y redes heterogéneas, desde el punto de vista de LTE-Advanced y su evolución.
Dr. Jose F. Monserrat es profesor Titular de Universidad en la Universidad Politécnica de Valencia (UPV). Obtiene el grado de Ingeniero de Telecomunicación con honores (primero de promoción) por la UPV en el 2003 y el grado de Doctor en Telecomunicación en 2007. Recibe el primer premio al mérito académico de la Comunidad Valenciana por su excelente rendimiento universitario en 2003 y el premio extraordinario de Tesis Doctoral de la UPV en 2008. Fue reconocido como joven investigador del año en 2009. En la actualidad es miembro de la acción europea COST IC1004 y trabaja activamente en diversos proyectos de investigación nacionales e internacionales todos relacionados con los sistemas de comunicaciones inalámbricos y la optimización de algoritmos de gestión de recursos en tecnologías IEEE y 3GPP de tercera y cuarta generación. Ha participado en varios proyectos Europeos (WINNER+, ICARUS, PROSIMOS, NEWCOM, EURO-NF, COMIC), siendo especialmente relevante su participación en WINNER+ donde lideró un paquete de trabajo en gestión de recursos radio para IMT-Advanced. También participó como experto invitado de la ITU-R (Naciones Unidas) en la selección de las tecnologías móviles de cuarta generación. Ha editado la edición especial de Febrero de 2011 de la revista IEEE Communications Magazine sobre sistemas IMT-Advanced y es coautor del libro de Wiley “Mobile and wireless communications for IMT-Advanced and beyond.
System architectures and networking solutions for highly constrained networked systems

Service-Oriented Architectures (SOA) are increasingly considered as a cornerstone to address the complexity, heterogeneity and interoperability challenges of nowadays information systems. In the first part of my talk, I will present the outcome of 3 years of applied research that I initiated on a multi-level service-oriented architecture for Wireless Sensor/actuator Networks (WSN). This architecture bridges the gap between heterogeneous devices and that supports network dynamicity, auto-configuration, service discovery, dynamic repurposing and interoperability with legacy systems. I will highlight the benefits of this work when applied to force protection solutions aiming at rapidly and efficiently protect areas (camps, compounds, forward operated bases, etc.). In the second part of the talk, I will present my contributions on Disruption Tolerant Networking (DTN), a research field where I have been active for 6 years. In tactical military ad hoc networks, the network suffers from frequent connectivity disruptions, making the topology intermittently and partially connected. End-to-end paths can exist temporarily, or may sometimes never exist, with only partial paths emerging. These disruptions could be caused by node mobility, radio perturbations, or the existence of very long delay links. Due to these disruptions, regular networking approaches to routing and transport do not fully work. New solutions must be proposed.
Dr. Jérémie Leguay is a research team leader at Thales Communications, in Colombes, France. He received his Engineering Degree (2003) from EFREI (École Française d'Electronique et d'Informatique) and a Master of Science (2004) in Computer Science from Linköping University in Sweden. From 2004 to 2007 he was a Ph.D. candidate at the Computer Science laboratory (LIP6) of Pierre & Marie Curie University and at Thales Communications where he conducted research on tactical ad hoc (MANET) networks and Disruption Tolerant networking (DTN). After 2 years working as a research engineer, he is currently managing a research team on network protocols and communication services in the contexts mobile networks, sensor networks and large-scale distributed systems. He is also coordinating the FP7 iTETRIS and the French ANR CROWD projects.
