Vehicular ad hoc networks have emerged recently as a platform to support intelligent inter-vehicle communication and improve traffic safety and performance. The road-constrained and high mobility of the vehicles, their unbounded power source, and the emergence of roadside wireless infrastructures make VANETs a challenging research topic. A key to the(More)
Vehicular Ad hoc NETworks (VANETs) have emerged as a platform to support intelligent inter-vehicle communication and improve traffic safety and performance. The road-constrained, high mobility of vehicles, their unbounded power source, and the emergence of roadside wireless infrastructures make VANETs a challenging research topic. A key to the development(More)
Cloud application portability and optimal resource allocation are of great importance in the realm of Cloud infrastructure provisioning. c-Eclipse is an open-source Cloud Application Management Framework through which users are able to define the description, deployment and management phases of their Cloud applications in a clean and intuitive graphical(More)
Cloud computing enables on-demand provisioning of computing resources to IT solutions, following a utility-based approach. Technology and standardization developments in traditional public utilities enable customers to seamlessly migrate across utility providers without being required to make changes to their home appliances. Dubbed as the fifth utility,(More)
Vehicular Ad hoc Networks (VANETs) have emerged as a platform to support Intelligent Transportation Applications. A key to the development of protocols and services for IVC lies in the knowledge of the topological characteristics of the VANET communication graph. This article aims provide a "higher order" knowledge in the time-evolving dynamics of vehicular(More)
VANETs have been envisioned as an infrastructure for deploying Vehicular Information Systems (VIS) that among others provide drivers with an up-to-date view on the prevailing traffic conditions. In this work we evaluate the benefits of caching vehicular information obtained from such VIS through VITP, a location-aware, application-layer communication(More)
Recent advances in VANET technologies have propelled the development and deployment of a wide variety of Vehicular Information Systems (VIS) to vehicles. Such systems provide real-time, crucial information, to drivers, ranging from collision avoidance warnings to the availability of road-side facilities. Despite the invaluable information provided by such(More)
Next generation Cloud applications present elastic features and rapidly scale their comprised resources. Consequently, managing and monitoring Cloud applications is becoming a challenge. This paper showcases the functionality and novel features of: (i) c-Eclipse, a framework for describing Cloud applications along with their elasticity requirements and(More)
