The paper reports an analysis about the convenience of employing multi-protocol label switching (MPLS) to provide mobility in wireless mesh networks (WMNs). In such networks, which are expected to serve a considerable number of mobile users, the efficient support of mobility is a non-trivial issue. The starting point of our work is proxy mobile IPv6 (PMIPv6), a standardised network-based protocol...
In this paper, we introduce a novel queue management technique for the buffer space at the base station of infrastructure 802.11 networks that considers mobile user's receiving characteristics. The maximum amount of the base station buffer that can be used by a given flow is updated proportionally to RTT, measured at the mobile nodes and sent to the base station my the mean of link layer acknowledgements...
This paper presents a system for a location-based discovery of points of interest, based on the current geographic position of mobile users. The proposed approach exploits a mixture of Web 2.0 technologies (for the localization of point of interests), positioning techniques and cross-layer networking schemes for a seamless navigation, while moving through different and heterogeneous wireless networks.
This article briefly describes the EU-funded Daidalos project, which designs and develops a communications infrastructure for next-generation networks to enable personalized, context-aware, composite services to mobile users. The fundamental concepts rely on federation of operators who create a pervasive environment for service provisioning, on integrated mobility, security, virtual identity for users,...
