This paper analyses the suitability of several satellite systems for direct-to-device connectivity using the 5G New Radio air interface. The selected geostationary satellites and low Earth orbit satellite constellations cover a wide range of systems, namely Inmarsat, EchoStar, GLOBALSTAR-2, Iridium NEXT, Lynk, and AST SpaceMobile. The conducted link power budget assessment shows that depending on ...Show More
A new link scheduling approach for millimeter wave wireless mesh network is presented. The proposed link scheduling solution is designed to work together with a multiple overlapping spanning trees-based routing schemes on a mesh network topology. The link schedule computation will minimize the end-to-end delay along a subset of shortest-hop paths from non-gateway nodes to a gateway node of the mes...Show More
This paper explores network design requirements and radio resource management (RRM) functionalities required to enable a heterogeneous millimeter-wave (mmW) network in both backhaul and access links. First, the envisioned design of a heterogeneous mmW network is outlined highlighting the main functional blocks and the key differentiating factors from non-mmW architectures. Next, the RRM functional...Show More
Static Wireless Mesh Networks (WMN) based on high capacity pencil-beam millimeter wave (mmWave) links offer an attractive solution for small cell backhauling in 5G networks. However, the delay targets in 5G are such that it is quite challenging to develop adequate link scheduling and routing mechanisms. Furthermore, the susceptibility of mmWave radio links to adverse weather conditions and other o...Show More
This paper presents some key findings w.r.t. the Radio Resource Management (RRM) in wireless Backhaul (BH) of mmWave networks. First, the envisioned design of mmWave backhaul architecture is outlined highlighting the most important newly needed functional blocks and in what they differ from a non-mmWave architectures. Next, the challenges and functionality of RRM techniques are discussed, focusing...Show More
The IEEE 802.15.4 standard defines a set of procedures to set-up a Low-Rate Wireless Personal Area Network where nodes self-organize into a logical communication structure through which data can be routed, hop by hop, from sources to destinations. The network formation of the IEEE 802.15.4 does not impose constraints on the topology. The ZigBee Alliance uses the IEEE 802.15.4 layers to build a com...Show More
This paper deals with the integration of available platforms and testbeds within the network of excellence CRUISE, which belongs to the VI IST framework. First, the existing testbeds are described in terms of application scenarios, hardware features and adopted communications protocols. Then, several considerations regarding the integration issues are given, involving diverse aspects, such as appl...Show More
The ability to access remote file storage from mobile devices enables a number of new use cases for storing and sharing data. We describe the design and implementation of a Remote Storage Client framework on Symbian OS, the leading smart phone OS on the market. Our work is inspired and informed by previous work like Coda [1]. We describe why Coda cannot be used directly in our target scenarios and...Show More
Amongst the activities of the European Commission IST research project-MIND is extensive consideration of the multi-homing issues in IP access networks. Analysis of the various multi-homing scenarios reveals diverse aspects of multi-homing relevant to both the operations of the access network as well as the hosts connected to it. The originality of the work presented in this paper arises from the ...Show More
In this paper we suggest a classification scheme for IP mobility protocols and propose a framework for comparing them. We then use the framework to provide an initial comparison of previous proposals for supporting micro-mobility. The authors are part of project BRAIN (Broadband Radio Access for IP based Networks)-a European collaborative project under the IST (Information Societies Technology) pr...Show More
