EVARILOS

Project name:
Evaluation of RF-based Indoor Localization Solutions for the Future Internet
Funding agency:
EU-funded project under ICT FP7, Call FP7-ICT-2011-8, Objective ICT-2011.1.6 Future Internet Research and Experimentation (c. FIRE Experimentation), contract number: 317989
Content:
The EVARILOS project addresses one of the major problems of indoor localization research: The pitfall to reproduce research results in real life scenarios suffering from uncontrolled RF interference and the weakness of numerous published solutions being evaluated under individual, not comparable and not repeatable conditions. Accurate and robust indoor localization is a key enabler for context-aware Future Internet applications, whereby robust means that the localization solutions should perform well in diverse physical indoor environments under realistic RF interference conditions. The objectives of the EVARILOS project are: Firstly, EVARILOS will develop a benchmarking methodology enabling objective experimental validation of and fair comparison between state-of-the art indoor localization solutions. Contrary to previous approaches, the EVARILOS benchmarking methodology not only considers accuracy metrics, but also complexity, cost, energy, and, most importantly, RF interference robustness metrics. Next, the project aims to improve the interference robustness of state-of-the-art localization solutions through (a) introducing multimodal approaches leveraging the diversity of different localization methods; (b) introducing environmental awareness and cognitive features; (c) by leveraging the presence of external interference. Thirdly, the EVARILOS benchmarking methodology and interference-robust localization solutions will be validated in two real-life application scenarios: healthcare in a hospital setting and underground mining safety. The main outcomes of the project are a public handbook on the use of the EVARILOS benchmarking methodology and the EVARILOS benchmarking suite. The latter will be implemented in two different testbeds belonging to the FIRE facilities (CREW and OpenLab) and will be publically available under open source licenses. We will further issue an open challenge for the best localization solution to promote the EVARILOS benchmarking methodology.

EYES - project

Project name:
Energy Efficient Sensor Networks
Funding agency:
EU
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.

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.

Steuerung

Project name:
Steuerung
Funding agency:
Telekom
Content:
Future industrial IT infrastructures and control systems will be heavily based on Wireless Sensor Networks (WSN) and distributed M2M communication infrastructures. IT based attacks specifically targeted to (industrial) control and sensor networks can have huge impacts. However sophisticated and highly specialized attacks are difficult to be detected in an automated way with conventional techniques. Most wireless communications use the RF spectrum. A wireless signal can be easily intercepted with receivers tuned to the proper frequency. Thus, messages transmitted can be overheard, and fake messages can be injected into the message to be corrupted or lost. The objective of the Steuerung project is to analyse the impact of known jamming methods on technologies widely-used in wireless sensor networks, i.e. Buetooth, Wireless HART, ZigBee. Moreove, new concepts will be developed to protect against new and unknown jamming attacks.
