In this paper, we present a solution that reduces the time spent on providing network access in multi-domain mobile networks where the authentication process is based on the Extensible Authentication Protocol (EAP). The goal is to achieve fast and smooth handoffs by reducing the latency added by the authentication process. This process is typically required(More)
In order to ensure end user devices are healthy enough to gain access to the network, providers are making use of advanced network access control solutions, which propose an evaluation of configuration information (posture) about the device itself before providing access to the network. However, current solutions are focused on intra-domain scenarios, where(More)
The appearance of recent standards about cooperative ITS architectures towards a reference communication stack has been an inflection point in the research about vehicular networks. The ISO Communication Access for Land Mobiles (CALM) and the ETSI European ITS communication architecture have paved the way towards real and interoperable vehicular cooperative(More)
Research on vehicular networks has increased for more than a decade, however, the maturity of involved technologies has been recently reached and standards/specifications in the area are being released these days. Although there are a number of protocols and network architecture proposals in the literature, above all in the Vehicular Ad-hoc Network (VANET)(More)
In recent years there has been a significant growth in the deployment of heterogeneous wireless technologies. Due to its diversity, new multi-interface terminals have appeared and pose new challenges to mobility management and security in wireless networks. In order to achieve a solution to these new challenges several standardisation groups are working to(More)
When enabling handover between different radio interfaces (e.g., handover from 3G to Wi- Fi), reducing network access authentication latency and securing handover related signaling messages are major challenging problems, amongst many others. The IEEE 802 LAN/MAN Standards committee has recently finished its standardization work in this area by defining the(More)
The International Standards Organization (ISO) and the European Telecommunications Standards Institute (ETSI) have defined a common ITS reference communications stack which have paved the way to new research lines in vehicular networks. Currently, most of the efforts have focused on the definition and testing of ITS applications operating over Internet(More)
