Composite Reconfigurable Wireless Networks: The EU R&D Path toward 4G |
| Bartolomé Arroyo-Fernández, José Fernandes, and Ramjee Prasad |
Empowering Next-Generation Wireless Personal Communication Networks
Next-generation wireless systems should provide to the user access to a broad range of services in a transparent way, independent of user location by making the technology invisible and embedded in the natural surroundings.
Luis Muñoz, Ramón Agüero, Johnny Choque, José Ángel Irastorza, and Luis Sánchez,; University of Cantabria; Marina Petrova and Petri Mähönen, Aachen UniversityDynamic Spectrum Allocation in Composite Reconfigurable Wireless Networks
Future wireless systems are expected to be characterized by increasing convergence between networks and further development of reconfigurable radio systems. In parallel with this, demand for radio spectrum from these systems will increase, as users take advantage of high-quality multimedia services.

Commonalities between the two most popular infrastructures, mobile cellular and TV broadcast, are such that a common framework for services and QoS management can be built, without the expense of starting from scratch in the design of a universal system.
Omar Benali, Karim El-Khazen, David Garrec, Michel Guiraudou, and Georges Martinez; Motorola Labs (CRM)Evolution in Wireless Systems Management Concepts: From Composite Radio Environments to Reconfigurability
The authors present a management system that has been developed for enabling wireless systems to operate in a CR context. The authors also address the necessary extensions to the management system for handling the impact of the reconfigurability context.

Performance of New Link State Advertisement Mechanisms in Routing Protocols with Traffic Engineering Extensions
This article presents several key results on the performance of the recently proposed OSPF-TE, with particular emphasis on OSPF-TE protocol traffic overhead and the impact of new link state advertisement triggering mechanisms on traffic-engineered routing accuracy.
Hussein M. Alnuweiri, Lai-Yat Kelvin Wong, and Tariq Al-Khasib, University of British ColumbiaIPv6 Anycast for Simple and Effective Service-Oriented Communications
The authors first review IPv6-based anycast communication and then raise several problems and provide possible solutions to these. Based on this background, they present the Anycast Address Resolving Protocol (AARP) to establish TCP connections with a specific anycast address, and then propose a routing protocol for intersegment anycasts. The proposed architecture makes anycast addresses more useful without (or with at most minimal) need for modifications/extensions to existing applications and/or upper-layer protocols.

A Federated Peer-to-Peer Network Game Architecture
A federated peer-to-peer game is one in which many small areas of interest within a game each supported using a peer-to-peer model are "knitted" together to form a game capable of supporting a very large number of players.
Sean Rooney, Daniel Bauer, and Rudy Deydier, Zurich Research LaboratorySelective Encryption for Consumer Applications
Selective encryption is a technique to save computational complexity or enable interesting new system functionality by only encrypting a portion of a compressed bitstream while still achieving adequate security.
Tom Lookabaugh and Douglas C. Sicker, University of Colorado at BoulderThe Quest for Personal Control over Mobile Location Privacy
How to protect location privacy of mobile users is an important issue in ubiquitous computing. However, location privacy protection is challenging. To address this issue, the authors propose an authorized-anonymous-ID-based scheme that eliminates the need for a trusted server or administration, which is assumed in the previous work.

The authors describe a new OSI-based model that can be used for the classification of residential gateways. It is applied to analyze current gateway solutions and draw evolutionary paths for the medium to long term.

The OSGi framework is a lightweight framework for deploying and executing service-oriented applications. The service-oriented approach is well suited to the dynamic environment envisioned for services gateways, but it creates unique challenges for application developers.
