Projects
Present
Future Dual-Mode Mobile Phones R&D (3G/WLAN)
The project consists in the evaluation and configuration of wireless LAN QoS and power saving mechanisms for NEC’s 3G/WLAN dual-mode terminals. Our work consists in evaluating different functionality options for the targeted mobile terminal requirements, design proprietary algorithms and provide the optimal configuration parameters for the chosen business cases.
WiMAX Base Stations R&D
The objective of this project is the design of NEC's WiMAX Base Station QoS schedulers for future product releases which use as efficiently as possible the available radio resources.
CARMEN – CARrier grade MEsh Networks (European FP7 Project)
The CARMEN project goal is to develop an architecture and the underlying technology for building wireless mesh networks capable of delivering carrier grade services at significantly reduced capital and operational expenditures. The architecture design will support the flexible integration of heterogeneous radio and MAC technologies, such as 802.11, 802.16 and DVB. Furthermore, it will build on self-configuration and self-management principles to reduce the time and effort of deployment as well as to optimize the mesh network's performance during operation.
Past
N906iL - Third NEC Dual-Mode Mobile Phone
The project consisted in the analysis of the WLAN part of NEC's third dual-mode terminal (3G/WLAN), N906iL, in order to optimize the performance of its QoS and power saving features.
N902iL - Second NEC Dual-Mode Mobile Phone
The project consisted in the analysis of the WLAN part of NEC's secondt dual-mode terminal (3G/WLAN), N902iL, in order to optimize the performance of its QoS and power saving features.
N900iL - First NEC Dual-Mode Mobile Phone
The project consisted in the analysis of the WLAN part of NEC's first dual-mode terminal (3G/WLAN), N900iL, in order to optimize the performance of its QoS and power saving features.
WiMAX-WiFi Interworking
The objective of this project was the analysis of different WiMAX-WiFi interworking scenarios focusing on the design and evaluation of solutions for guaranteeing end-to-end QoS.
IP-based UMTS Radio Access Networks
The project focused on the design of solutions to provide the required QoS in IP-based UMTS Terrestial Radio Access Networks (UTRANs) and the minimization of the signaling overhead required for VoIP services. Several proposals were designed and evaluated.
EU IST project Moby Dick
In order to continue to evolve 3rd Generation mobile and wireless infrastructure towards the Internet - targeting IST 2000 IV 5.2 "Terrestrial Wireless System and Networks", the Moby Dick project defined, implemented, and evaluated an IPv6-based mobility-enabled end-to-end QoS architecture starting from the current IETF's QoS models, Mobile-IPv6, and AAA framework. A representative set of interactive and distributed multimedia applications served to derive system requirements for the verification, validation, and demonstration of the Moby Dick architecture in a testbed comprising UMTS, 802.11 Wireless LANs and Ethernet. When the existing applications or the underlying architectures did not provide what was required, the necessary modification were undertaken.
QoS for Wireless LANs (IEEE 802.11e)
The goal of the project was to contribute to the standardization process of QoS features in the IEEE 802.11 Enhancements Task Group (802.11e). We proposed our own approach to Task Group ‘E’, in line with IETF’s Differentiated Services architecture, and evaluated it analytically and via simulation.
