Adaptive Data-Link to optimise Interactive Voice over Wireless, Local Networks - project
| Project name: | Adaptive Data-Link to optimise Interactive Voice over Wireless, Local Networks |
| Funding agency: | |
| Content: | Users demand for a high quality wireless Internet. However, the wireless access is the bottleneck in the world-wide communication systems, since wireless links often have small capacity and a temporally varying channel quality. Thus, optimising the transmission performance of wireless Internet is promising. |

EYES - project
| Project name: | Energy Efficient Sensor Networks |
| Funding agency: | |
| Content: | The European EYES project is researching the potential of so-called sensor networks. These networks consist of spontaneously organized networks of very small, simple nodes that perform sensor or actuators duties. In this context, we are specifically investigating the problem of distributed algorithms (e.g., consensus or converge-cast) in such environments, as well as the question of supporting semantic addressing ("Give me the temperature from any sensor in the living room") in the transport, network, link- and MAC-layer. Key constraints in such networks are energy supply and energy efficiency and the need to do with minimum amounts of computational resources. |

Leveraging channel predictions for OFDM - project
| Project name: | Leveraging channel predictions for OFDM |
| Funding agency: | |
| Content: | Short-term predictions about the channel quality of an OFDM permit to improve the efficiency of resource usage. As an example, consider a cellular system that uses OFDM in the downlink. Usually, the various OFDM sub-carriers' quality varies both over time and over mutliple users. If this quality is known in advance, various scheduling techniques can be used to, e.g., maximize the available throughput for all users. It is the goal of this project to investigate algorithms to support such prediction-based sub-carrier scheduling as well as develop architectures, mechanisms, and protocols to implement this concept in real systems. |

ORAN - project
| Project name: | OpenFlow-basierten Switches für Forschung und Lehre |
| Funding agency: | A collaboration project between Technical University Berlin (TUB) and European Center for Information and Communication Technologies (EICT GmbH) |
| Content: | OpenFlow [1] enables experiments in developing efficient networking protocols and architectures by decoupling (at least partially) the intelligence from the data path of a switch/router and delegating it to an external control that can be programmed by network researchers. In the OpenFlow approach experimental protocols are implemented in an external controller without modifications of the routers data-path processing algorithms. For this purpose the switch has to, however, be able to support the OpenFlow Protocol. While this approach has attracted a lot of attention in the research community, the amount of switches following high performance industry standard on one hand, but also being relatively open for flexible configuration and supporting OpenFlow is rather limited. The goal of the ORAN project is to design and prototype an OpenFlow-enabled Ethernet switch based on an AdvancedTCA (ATCA) industrial standard. This standard defines highly modular components that are being used mostly by telecommunication operators to assemble networks consisting of processing elements (computers) and data transport modules (Ethernet switches, mobile base-stations, optical transmission cards etc.) The modularity and the fact that there is a large market for ATCA components lead to low prices for the individual components. The advantages of using ATCA for an experimental network are manifold: composability of components for special purposes (e.g., wireless or optical transmission), a well-introduced industry standard (availability of components is guaranteed over years) and low cost. The project shall develop a prototypical composition of ATCA components that implement OpenFlow and establish an example for other universities and research institutions to go out and build their own that jointly creates a larger test facility. Project Duration: 05.2010-07.2011 |

Proxy-based congestion and flow control - project
| Project name: | Proxy-based congestion and flow control |
| Funding agency: | |
| Content: | In mixed wired / wireless networks, the efficient support of large-scale traffic streams is of pivotal importance. An important aspect is congestion and flow control, where the traditional end-to-end paradigm is increasingly questioned. More and more, proxy- or middlebox-based approaches are gaining popularity. In this project, we investigate the use of congestion control proxies that work by exploiting joint congestion control information of multiple traffic streams. |

SeQoMo - project
| Project name: | Security, QoS and Mobility |
| Funding agency: | |
| Content: | SeQoMo (Security, QoS and Mobility) is funded by Siemens AG. The focus of this project is to investigate the suitability of IP-based networks for support of mobility under the perspective of advanced mobility mechanisms, security, and Quality of Service (QoS). The investigation of mobility mechanisms has resulted in the development of the MOMBASA architecture and software environment that enables the use of multicast for mobility support. The QoS support rests upon the concept of a binding update which is conditionalized upon the availability of sufficient resources in a new path during a handover. The security part has focused on authentication, authorization and denial of service protection in mobile, IP-based networks. Integrating these three components into an overall secure, QoS-capable mobility architecture based upon IP protocols is the ultimate goal of this project. |

The MiniWatt project
| Project name: | The MiniWatt project |
| Funding agency: | |
| Content: | The MiniWatt project is a joint effort of several German universities and companies, funded by the German government. Its goal is to investigate and develop mechanisms to reduce the electro-magnetic exposure that is caused by wireless mobile communication. The activities at the TKN TUB group are focused on exploiting (ad hoc) multi-hop communication principles to reduce transmission power as a means to reduce electro-magnetic exposure immitted power and / or energy. The constraint is that multi-hop communication should not reduce the end-to-end capacity of a network. |

TCP/IP over Air - project
| Project name: | TCP/IP over Air |
| Funding agency: | |

WIGWAM - project
| Project name: | Wireless Gigabit With Advanced Mobility Support |
| Funding agency: | |
| Content: | The objective of WIGWAM is the design of a complete system for wireless communication with a maximum transmission data rate of 1 Gbit/s. The targeted spectrum is the 5 GHz band and the extension bands 17, 24, and 60 GHz. Depending on the mobility of the user, the data rate should be scalable. Besides typical application areas, i.e. "hot-spots" and home/office scenarios, WIGWAM covers the toppic of providing high data rates for high mobility application scenarios. The Telecomunicaiton Network Group (TKN) of TU Berlin is involved in the sub-project "Radio Links With Highest Data Rates on Fast Altering Radio Channels Based on WLAN Principles" in which it contributes the support for fast and seamless handover. |
