Cooperative Wireless Networking: Research Challenges

Dienstag, 2. Oktober 2018 11:20

TeWi Kolloquium in cooperation with Lakeside Labs GmbH.

17 October 2018, 10.00 am – Lakeside B04, entrance b, 1st floor

Today’s internet is being populated, in its fringes, by large number of devices that are wireless and/or cellular enabled. Despite the fact that such devices are often in the vicinity of each other, communication among them follows the end-to-end principle and as such, traditional data transmission approaches do not take advantage of the physical proximity of devices.
In the area of computer networks, the concept of cooperation has been applied to mitigate such effects, in different layers of the OSI stack. For instance, in wireless networks, cooperative networking techniques are being applied in OSI Layer 1 (based on diversity); in OSI Layer 2 (based on overhearing); in OSI Layer 3 (based on estimation); and in the above layers, for instance, as occurred with overlaying (e.g., P2P).
This talk is based on the research findings and contributions that the speaker has been doing to the field of cooperative networking. The talk will go over the sustainability of cooperative networking, by studying the inclusion of derived models, such as user-centric networking, in the Internet wholesale model, and by investigating the basic requirements for the success deployment of cooperative networking mechanisms, in terms of the incentives that devices need to have to participate in cooperative activities. From a pure networking perspective the talk will focus on cooperative networking mechanisms related to few-hop relaying and cooperative routing aiming to take advantage of any opportunity to communicate in intermittently connected wireless networks.
The talk will end with an overview of the research challenges to apply cooperative networking principles to the development of an Internet encompassing a huge number of embedded devices able to produce a large amount of data, where there are potential advantages in combining communication and computation in what is called in this talk “cooperative computing”. As example, the talk will focus on autonomic vehicle technology, which is being driven by advances in sensing, computing and networking technologies. On the one hand, autonomous driving on urban roads has seen significant progress in recent years. On the other hand, autonomous Unmanned Aerial Vehicles (UAVs) have received increasing interest to tackle several use-cases from environment monitoring and emergency situations, to relaying communications to isolated areas.

Emerging Communication

Donnerstag, 5. Dezember 2013 13:27

Monday, 9 December 2013 at 2 pm in room Z.1.09

The presented work considers the relation of Shannon-type information to those semantic and hermeneutic aspects of communication, which are often referred to as meaning. It builds on considerations of Talcott Parsons, Niklas Luhmann and Robert K. Logan and relates them to an agent-based model that reproduces key aspects of the Talking Head experiment by Luc Steels. The resulting insights seem to give reason to regard information and meaning not as qualitatively different entities, but as interrelated forms of order that emerge in the interaction of autonomous (self-referentially closed) agents. Although on first sight, this way of putting information and meaning into a constructivist framework seems to open possibilities to conceive meaning in terms of Shannon-information, it also suggests a re-conceptualization of information in terms of what cybernetics calls Eigenform in order to do justice to its dynamic interrelation with meaning.

Optimal transmission policies for energy harvesting communication devices

Mittwoch, 27. November 2013 12:24

2 December 2013, 2 pm

Michele Zorzi, University of Padova, Italy & University of California, San Diego talks at the Lakeside Labs GmbH, Lakeside Park Building 4, entrance b, 1st floor

Energy Harvesting (EH) is a new paradigm in Wireless Sensor Networks (WSNs): sensor nodes are powered by energy harvested from the ambient, rather than by non-rechargeable batteries, thus enabling a potentially perpetual operation of the WSN. However, Energy Harvesting poses new challenges in the design of WSNs, in that energy availability is random and fluctuates over time, thus calling for radically different energy management solutions. In this talk we investigate the following fundamental question: how should the harvested energy be managed to ensure optimal performance? First, we consider a sensor powered by EH which senses data of varying importance and  reports them judiciously to a Fusion Center. Assuming that data  transmission incurs an energy cost, our objective is to identify low-complexity policies that achieve close-to-optimal performance, in terms of maximizing the average long-term importance of the reported data. We first consider schemes that rely on the assumption of perfect knowledge of the amount of energy available in the battery. Subsequently, we investigate the design of operation policies that maximize the long-term reward under imperfect knowledge of the State-Of-Charge (SOC). Moreover, for both scenarios, we explore the impact of time-correlation in the EH process, showing that simple adaptation to the state of the EH process yields close-to-optimal performance, without requiring full knowledge of the SOC of the battery.

Michele Zorzi is a Professor at the Department of Information Engineering of the University of Padova. Prior to his current appointment, he was employed at the Politecnico di Milano, the University of Ferrara and the University of California at San Diego, with which he still has an active collaboration. He is an IEEE Fellow. His main research interests are in the area of wireless communications and networking, sensor networks and IoT, underwater communications and networks, cognitive networking, and energy-efficient protocol design. His work is widely cited, with a total of more than 11000 citations and an h-index of 52.

Achtung, Stau nach Unfall!

Dienstag, 15. November 2011 8:51

Freezing rain causes an accident on a highway. Sensors attached to cars detect this event and communicate it via WLAN to other cars to inform oncoming drivers. The implementation of new WLAN technologies for car-to-car communication is running at full speed. Bettstetter and his team have also been tackling this problem. Their key ideas lead to filing two patent applications.

Analysis of Wireless Networks with General Node Distribution

Dienstag, 20. September 2011 14:53

Martin Haenggi, Professor of Electrical Engineering and a Concurrent Professor of Applied and Computational Mathematics and Statistics at the University of Notre Dame, Indiana, USA, will give a

talk at the Lakeside Labs, B04.1.114, on Thursday, 29 September 2011, 2.00 pm.

The analysis of large wireless systems relies on a spatial model for the node distribution. Such spatial modeling has been largely restricted to the Poisson point process (PPP), since its attractive analytical properties permit the derivation of closed-form expressions for the interference distribution, outage probabilities, and the spatial throughput. The Poisson model, however, is only accurate if all nodes form a PPP and ALOHA is used as the MAC protocol. Hence, in many cases, the locations of the transmitters are better modeled by clustered or hard-core models. After reviewing the most important results for the Poisson case, we discuss novel analytical techniques that permit extensions to general stationary point processes.

Free admission for everybody interested.
