Triggered by the demand of ubiquitous Internet connectivity and the availability of different wireless technologies, several IP mobility support protocols have been standardized in the past. Each solution provides a specific functionality (e.g., host or network mobility) and/or requires operations of particular nodes (e.g., client or network based). The(More)
This poster presents the key ideas behind the ICT CROWD (Connec-tivity management for eneRgy Optimised Wireless Dense networks) project, funded by the European Commission. The project moves from the observation that wireless traffic demand is currently growing exponentially. This growing demand can only be satisfied by increasing the density of points of(More)
—Opportunistic Routing (OR) takes advantage of the broadcast nature of the wireless medium to increase reliability in communications. Instead of selecting one node as the next-hop forwarder, OR selects a set of candidates to forward the packet. In this way, if one of them does not receive the packet from the source, another candidate will be able to do it;(More)
The current wireless network architecture needs to be re-thought to support mobility in very dense and heterogeneous network deployments. We propose and experimentally evaluate a novel SDN-based architecture which makes use of DMM concepts to deploy fast, flexible, reliable, and scalable mobility management mechanisms at both local and regional scopes. Our(More)
—The significant growth in mobile data traffic and the ever-increasing user's demand for high-speed, always connected networks continue challenging network providers and lead research towards solutions to enable faster, scalable and more flexible networks. In this paper we present the CROWD approach , a networking framework providing mechanisms to tackle(More)
Research on vehicular communications has been quite extensive over the past few decades. Most of the initial studies were theoretical and research has just recently moved to more experimental works. Conducting real field operational tests is extremely challenging due to the number of vehicles required , the lack of control over the environment and the cost(More)
— The Wireless-Optical Broadband Access Network (WOBAN) is a promising access architecture that combines the high performance of optical networks with the ubiquity and convenience of wireless technologies. This article proposes a network-based mobility framework that is specially tailored for WOBANs. The proposed architecture is based on Proxy Mobile IPv6(More)
—Current trends on mobile traffic show an exponential grow of the traffic consumed by users from smartphones and other portable devices. The explosion of traffic in cellular networks has forced operators to start deploying solutions to alleviate the congestion on their capacity-limited and expensive radio access networks. One of the solutions being(More)
