Major wireless operators are nowadays facing network capacity issues in striving to meet the growing demands of mobile users. At the same time, 3G-enabled devices increasingly benefit from ad hoc radio connectivity (e.g., Wi-Fi). In this context of hybrid connectivity, we propose Push-and-track, a content dissemination framework that harnesses ad hoc(More)

Some multimedia content may be divisible into independently routable components, e.g. audio and video flows. As a result media content adaptation services may be linked in serial, parallel and hybrid configurations to form a directed, acyclic graph of composed services. We specify a distributed service path selection scheme for the construction of composed(More)
Cooperative ITS systems are expected to improve road traffic safety and efficiency, and provide infotainment services on the move, through the dynamic exchange of messages between vehicles, and between vehicles and infrastructure nodes. The complexity of cooperative ITS systems and the interrelation between its components requires their extensive testing(More)
Enabling a seamless experience for mobile users while dealing with multi-access networks is a great challenge for wireless access providers. Towards this goal, the IEEE 802.21 Working Group is elaborating the needed mechanisms and the standardization effort has led to a Media Independent Handover Services (MIHS) framework that is now ready for deployment.(More)
In this paper we review the progress of an ongoing work which aims at designing and setting up a large-scale open testbed for testing, verification and validation of IPv6-based ITS components. A European Commission partially funded project called ANEMONE provides the ground for the presented architecture by introducing the widest range of access networks(More)
Enabling content sharing among mobile users is a promising application for opportunistic networks. Clearly, collocated people are likely to share mutual interests. In this context, disseminating contents through opportunistic communications could be more efficient than passing through central servers. We implemented PACS (Prevalence-Aware Content(More)
The number of industrial applications relying on the Machine to Machine (M2M) services exposed from physical world has been increasing in recent years. Such M2M services enable communication of devices with the core processes of companies. However, there is a big challenge related to complexity and to application-specific M2M systems called ―vertical(More)
Future mobile tactical networks are being developed to support an increased variety of data services (e.g. Blue Force Tracking, intelligence image or video reporting) in addition to the more traditional voice services. Such networks rely on an IP-based MANET stack, running over a UHF (Ultra-High Frequency) radio interface. Unlike legacy VHF (Very-High(More)
This work presents the modeling methodology of the iTETRIS platform to integrate and simulate ITS applications. iTETRIS is a modular and open-source simulation platform composed of four key modules: the network simulator ns-3, the traffic simulator SUMO, an ITS (Intelligent Transportation System) application simulator, and a central federating module called(More)
