IPANEMA. Improving user exPerienced quAlity usiNg multiple wirEless interfaces siMultaneously And network coding

Logo_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).

ARTICO. Architecture enabling the autonomous opeRation of complex, heTerogeneous and dynamIC wireless netwOrks (TEC2008-06826/TEC)

Logo_Artico

Project ARTICO aims to carry out research on mobility management- and routing-related in managed as well as unmanaged wireless networks, and to study the implications of extending them to more complex hybrid networking scenarios that combine professionally managed legacy networks and self-managed all-wireless networks. ARTICO defines four major research goals:

  • Handling the heterogeneity of single-hop wireless access networks. Connection admission control and intelligent interface selection algorithms.
  • Efficient routing algorithms for multi-radio multi-channel multi-hop large-scale wireless networks.
  • Revisiting the above issues when combining next generation networks and self-organized wireless network into hybrid wireless networks.
  • Adaptation and extension of the EXTREME experimentation framework so as to evaluate most of the above concepts experimentally in three experimentation environments: 1) a controlled UMTS experimentation platform, 2) a Wireless Mesh Network deployment, and 3) an environment to test hybrid network scenarios.

All this work was carried out by the IP Technologies Area of the CTTC.

 

DESSERT. Distributed interface selection for seamless terminal mobility across wireless heterogeneous networks (Industrial – Cisco)

Logo_cisco

The research goal of the project is to study techniques for the provision of the information needed for a multi-interface mobile device to select the most appropriate network interface to send/receive its traffic at each moment of the communication as well as the definition of the interface selection algorithm itself. This project has been funded by an unrestricted gift by the Cisco Research Centre.

The FREEDOM project encompasses the collaboration in different research areas of mobility (radio access, IP, spectrum management, etc.) to study future wireless communications networks, potential improvements for optimal network planning and management, and impact of mobile devices’ evolution in such networks.

More specifically, the work of the IP Technologies Area focused on two main topics, namely Voice over IP (VoIP) and Peer-to-Peer (P2P), which were evaluated from a networking perspective, that is, the support that the network should offer to these types o communications for optimal performance. Furthermore, these technologies were experimentally evaluated over the EXTREME Testbed, with particular emphasis on 3G-WLAN heterogeneous networks that also feature ad hoc networks

DYNAMO. Dynamic Communication and Networks (COST Action 295)

Logo_cost

The main objective of COST Action 295, “DYNAMO” is to provide foundations, models, algorithms, and general tools for dynamic communication networks. These new decision-support tools favour the study and the efficient design of applications for networks of decentralized interacting and evolving entities, experiencing possibly brutal modifications of their environments. DYNAMO integrates the state-of-the-art scientific knowledge from the fields of Algorithms, Discrete Mathematics, Distributed Computing, and Mathematical Optimization, relevant to dynamic communication networks, in order to develop decision-support network technologies. These sophisticated decision-support tools enables overcoming the increased complexity of questions induced by the dynamics of advanced decentralized systems. Among the main problems tackled by DYNAMO are: placement of equipment, spectrum assignment, bandwidth allocation, infrastructure design, and distributed systems design. This is aiming at helping optimizing the deployment and usage of high-end technology communication networks, like mobile networks, radio networks, cellular networks, satellite networks, ad-hoc networks, and sensors networks, as well as of societal-driven emerging information technologies, like the WWW, and P2P networks.

Logo_Planets

PlaNetS intends to contribute to the overall goal of eEurope 2005, to provide cost effective broadband access to all European citizens. The broadband access will be based on a converged network unifying the current heterogeneous networks. The unification is expected to include also wireless access networks, cellular networks and WLAN. The converged network will be centred on the introduction of the next version of the Internet Protocol IPv6. PlaNetS will play a key role in this introduction. An IPv6 implementation scenario will be worked out and lab trials will be built up completely based on IPv6, including monitoring, remote control, automation, surveillance and related features.
