BeFEMTO. Broadband Evolved FEMTO Networks ICT-FP7-248523
BeFEMTO aims to research and develop evolved femtocell technologies, mainly focusing on the novel concepts of networked femtocells, femtocell as fixed relays in macrocells, and mobile femtocells. The scope and tangible results of BeFEMTO are (among others): 1) self-optimization techniques, 2) intelligent interference management, 3) cooperative networked femtocells, 4) mobile femtocells, and 6) validation of developed technologies using testbeds and simulation tools. More information available at: http://www.ict-befemto.eu/
The work of the IP Technologies Area of the CTTC in BeFEMTO focuses on:
- WP2 (Use Cases, Requirements and System Architecture). Definition of System requirements, Key Performance Indicators, and Design of the network architecture for all-wireless networks of femtocells
- WP5 (Femtocells Access Control, Networking, Mobility, and Network Management). Design of routing approaches and local mobility management strategies for all-wireless networks of femtocells, as well as their integration/interaction with the architecture defined by 3GPP.
- WP6 (Integration & Proof of Concepts). Design and deployment of an all-wireless network of femtocells testbed. Evaluation of some of the concepts conceived in WP5.

LENA. LTE-EPC Network Simulator
Ubiquisys, the developer of intelligent cells, and the IP Technologies Area of CTTC are working together to develop the world’s first open source product-oriented LTE network simulator.
The simulator will provide a common platform for LTE femto vendors and LTE macro vendors to evaluate their different solutions. The advantage for operators is that they can be sure that large and small cells from different vendors will work harmoniously before they are deployed.
In WCDMA networks, femtocells and macro cells work independently, but in LTE all cells work together as a single SON. This means that the adaptive behaviour of femtocells and macro cells is interdependent.
Simulators are important because they can evaluate product behaviour in a mature, densely deployed and heavily used network, at a time when real deployments are in their infancy. Ubiquisys made extensive use of a WCDMA network simulator during the development of its first generation of intelligent femtocells.
The open source LTE simulator is based on the popular ns-3 network simulator for internet systems. The development of the LTE simulator is open to the community in order to foster early adoption and contributions by industrial and academic partners.

IPANEMA. Improving user exPerienced quAlity usiNg multiple wirEless interfaces siMultaneously And network coding (Industrial - Cisco)
The improvement in the per-user capacity of next generation wireless access technologies is continuously trailing the ever increasing bandwidth requirements of mobile IP services. For this reason, complementary solutions are being investigated by the research community to fulfill the same requirements using existing wireless technologies. With this respect, a promising solution is to use multiple access technologies simultaneously in order to get an aggregated bandwidth that is sufficient to provide a satisfactory Quality of Experience (QoE) to the user. State-of-the-art solutions for the simultaneous use of multiple access links suffer from the delay dispersion problem. Coding the information to be sent over the multipaths at the source is a promising technique to address this problem. The project aims to design and implement a packet encoder/decoder pair to achieve better throughput/delay tradeoffs when compared with traditional routing-based solutions.
The project is in collaboration with the Cisco Research Center in San José (California, US).
SYMBIOSIS - System-level studY for coping with MoBIle data grOwth in evolved cellular networkS and future Internet environmentS (TEC2011-29700-C02-01)
SYMBIOSIS mainly focuses on studying, conceiving, and evaluating network-level services (e.g., routing, mobility, global resource management) towards a more efficient operation of mobile broadband networks at a global scale. In particular, SYMBIOSIS aims:
- To improve cellular network performance by having in mind the requirements posed by mobile data and how the mechanisms under study by the data networking community can help (e.g., overlay network service provisioning, distributed location management, self-organized interference management in dense uncontrolled deployments).
- To put cellular networks into a global context and to study network schemes enabling their integration with other networks (using the same or different technologies). In this direction, we will explore schemes defined to solve critical Internet problems, such as routing scalability (e.g., LISP). This also includes ways of providing critical network-level services at a global scale (e.g., routing, mobility). Scenarios representing various degrees of integration will be evaluated.
This project is in collaboration with the CCABA group of Universitat Politècnica de Catalunya (UPC)
