| Deliverable 1.2 | Top-level architecture for providing seamless QoS, security, accounting and mobility to applications and services |
Abstract:
cbd infused beauty products This document investigates concepts and architectures for providing seamless QoS, security, accounting, billing and mobility to applications and services using IP based networks. While the basic architecture – BRENTA (presented in the BRAIN Project) – is a pure End-System-Centric QoS architecture, several major and important enhancements are introduced to cover network aspects, AAA and Ad Hoc requirements. Extensions to BRENTA are developed to include a full specification of an End-to-End Negotiation Protocol for negotiating application layer QoS parameters and capabilities. Further, different operating system QoS specific functionalities are studied, in order to analyse how ESI (an important interface within BRENTA) functionality can be mapped to Windows and Linux platforms. The support of terminals operating in an Ad Hoc environment is discussed considering necessary extensions to BRENTA. A Domain Model defining different administrative network domains is derived from the use cases of MIND Deliverable D1.1. Based on this model, an analysis of appropriate security aspects is performed. Possible interactions between service and transport domains for setting up multi-stream multimedia QoS-aware sessions are studied. A generic billing and accounting architecture is derived and its relation to the service and transport domains is shown, based on some specific scenarios. Finally this document includes an overview of the giving support to help specifying and evaluating application and service level trials conducted by WP6 trials.

| Deliverable 2.2 | MIND protocols and mechanisms specification, simulation and validation |
Abstract:
This Core Report of the deliverable presents the results of the IST-MIND network studies. An Annex providing supporting material is available as a separate document. The objective of this work package was to extend the concepts developed in IST-BRAIN for IP mobile networks by researching the technologies required to support users within the new topologies of ad hoc, self organising and meshed networks. The generic case of interconnected mesh networks presents a level of complexity many times that addressed in IST-BRAIN and in consequence the approach adopted has been to develop a framework based on the eventual building blocks of the solution. MIND identifies three specific ad hoc network scenarios from which the deliverable explores the commonality of architectural approach together with specific analyses of the requirements for layering, mobility management and quality of service issues. The concept of multi-homing as applied to ad hoc networks is introduced and an analysis of multicast within ad hoc networks resulted in proposals for a specific new network protocol. Finally a series of more general observations for the design of ‘beyond 3G’ networks is present

| Deliverable 3.2 | Functional specification of technological enhancements for HIPERLAN/2 to meet the requirements of a potential beyong 3D System |
Abstract:
This deliverable focuses on enhancing the HIPERLAN/2 (H/2) air interface to meet the requirements of new MIND services and usage scenarios. In the first section, the air interface challenges for each of the MIND usage scenarios are investigated. To efficiently support the nomadic worker usage scenario the gains of the direct mode of H/2 are exploited. Presented are combined power control and link adaptation schemes applied to ad-hoc fringes, which are utilised as extension to a permanent access network. Sophisticated RRM scheduling schemes are introduced which are then applied to single and multihop communication. As for the medical care scenario, increased link distances and routing in wireless mesh environments pose the biggest challenges. Based on measurements, channel and pathloss models for a mesh environment are thus presented. These are used to investigate the performance of H/2 by means of link and system level simulations. Further, a collision free heuristic cross-layer QoS algorithm for routing in a mesh network is introduced and analysed. Then, the rapidly changing topology in the direct vehicle-to-vehicle multihop communication of the leisure scenario poses high demands on the scheduling algorithms. Various scheduling and link adaptation schemes for this scenario are presented. In the second section, schemes to overcome the limitations of low-power 5GHz OFDM systems regarding terminal velocity and link distance are analysed. Thoroughly investigated are midambles together with decision directed channel estimation, decision feedback channel estimation techniques, receive diversity and differential modulation. As for enhanced transmission ranges, various concatenated channel and space-time coding schemes combined with beamforming are analysed. To allow for outdoors deployment scenarios, a novel channel pre-equalisation scheme is investigated which mitigates large channel delay spreads. To yield higher throughput, incremental redundancy is investigated. Further investigations aim on the applicability of adaptive modulation with simulations conducted on both link and protocol level. In addition to the physical layer technologies, the analysis includes a summary of the required enhancements on the DLC and RLC specifications of H/2. A flexible signalling concept to support H/2 PHY mode extension profiles is introduced. Finally, in the third section a description of the H/2 testbed capabilities and suggested trial experiments is presented.

| Deliverable 3.3 | Methodologies to identify spectrum requirements for systems beyond 3G |
Abstract:
Efficient usage and availability of radio spectrum is a key prerequisite for wireless mobile services. Current methodologies to estimate spectrum requirements are limited and should be augmented to allow improved estimations, taking into account the vision for systems beyond 3G, which includes the cooperative usage of different wireless systems and a broad, ever increasing range of services. In this deliverable spectrum requirements estimation methods used for current specified wireless systems are reviewed with respect to new spectrum requirements arising from the predictions of future services and systems beyond 2010. Current methodologies are spreadsheet based, limited to a selected example service/market scenario and restricted in the examined deployment scenarios. As the current methods do not take into account convergence scenarios and cooperative networks, a new spectrum requirement methodology estimation framework is proposed and outlined in this deliverable to accomplish the envisaged scenario of ubiquitous mobile services and ambient wireless networks foreseen in the next decades. Flexible, statistical methods and Monte-Carlo simulation models are suggested for the estimation of frequency requirements. Such models allow the consideration of spatial and temporal distributions of the market requirements and network deployment scenarios in virtually unlimited flexibility. In the proposed methodology framework relevant parameters are defined as statistical distribution functions, the results are not fixed spectrum numbers but a range of results, reflecting the broad range of assumptions used in the modelling which reflect also future scenarios of spectrum sharing and inter-working of different radio access systems. This deliverable also provides valuable information to assist future spectrum identification/assignment discussions for mobile communication within International Telecommunication Union (ITU) and upcoming World Radio Conferences in 2003 and 2006,where suitable frequency bands for systems beyond 3G shall be identified to be used from year 2015 onwards.

| Deliverable 6.4 | MIND Trials Final Report |
Abstract:
The objective of WP6 was to build a trial system in order to test, integrate and validate the key concepts issued from the IST project BRAIN with emphasis on terminal, user and service mobility, QoS support, multiservice environment and user customization over multiple networks. As a final output of the WP6 in MIND we implemented the “nomadic worker” scenario by integrating testbed capabilities across different locations. The scenario was taken from the visions of the former BRAIN project and from the scenario definition phase of MIND.
The trials relied on various platforms, running at different premises across Europe. These different testbeds were used to independently develop various pieces for the demonstrated complex scenario. These efforts were taken during the first phase of the project and referred as standalone results in this document. These results are available on: enhanced radio interfaces, micro mobility protocol implementations, QoS solutions for mobility scenarios, adaptive applications for the rapidly changing network conditions and vertical handover between different access technologies. Early co-operation has ensured that the different elements could then be integrated to show the more complex scenarios. Further, some of the testbeds have been interconnected via IPv6 networks to demonstrate full mobility concepts. The full scenarios involve the networking elements from a large IP network to broadband wireless interface and new-dedicated services and applications.
This document introduces all the standalone and combined experiments and demonstrations. The result of this work is a successful demonstration of some of our visions about the next generation mobile systems.
