—An important requirement for Internet protocol (IP) networks to achieve the aim of ubiquitous connectivity is network mobility (NEMO). With NEMO support we can provide Internet access from mobile platforms, such as public transportation vehicles , to normal nodes that do not need to implement any special mobility protocol. The NEMO basic support protocol(More)
The Network Mobility (NEMO) Basic Support protocol enables mobile networks to change their point of attachment to the Internet, while preserving established sessions of the nodes within the mobile network. When only a non-nested mobile network is considered, the so-called triangle routing is the main problem that should be faced. In Mobile IPv6, the Route(More)
The growing interest in multicast applications for the Internet, that will increase with the introduction of active network technology, brings out the need for providing effective congestion control mechanisms. This paper studies the problems and specific requirements for multicast congestion control. From this study, a general mechanism is proposed and its(More)
This paper deals with multi-class classification for linguistic fuzzy rule based classification systems. The idea is to decompose the original data-set into binary classification problems using the pairwise learning approach (confronting all pair of classes), and to obtain an independent fuzzy system for each one of them. Along the inference process, each(More)
IP mobility support has been a hot topic over the last years, recently fostered by the role of IP in the evolution of the 3G mobile communication networks. Standardization bodies, namely IETF, IEEE and 3GPP are working on different aspects of the mobility aiming at improving the mobility experience perceived by users. Traditional IP mobility support(More)
In this paper we analyse the provision of enhanced communications between vehicles. It is expected that vehicles will have several communication devices, and that a specialised node will provide external connectivity to these devices, i.e. the devices in the vehicle form a Mobile Network. We propose the use of Network Mobility communication solutions for(More)
Network Mobility (NEMO) Basic Support Protocol enables mobile networks to change their point of attachment to the Internet, while preserving established sessions of the nodes within the mobile network. NEMO basic solution is an extension of Mobile IPv6 and it is based on tunnelling, which leads to suboptimal routing, packet overhead and latency, especially(More)
—In this paper, we propose a novel mechanism for application of an IPv6 automatic address configuration technique to vehicular ad-hoc networks. The solution consists of combining standardized IPv6 schemes with geographic routing function-alities, which enables the matching of geographically-scoped network partitions to single IPv6 multicast-capable links.(More)
The ability of offloading selected IP data traffic from 3G to WLAN access networks is considered a key feature in the upcoming 3GPP specifications, being the main goal to alleviate data congestion in cellular networks while delivering a positive user experience. Lately, the 3GPP has adopted solutions that enable mobility of IP-based wireless devices(More)
