Abstracts of the presentations and demos:
Welcome and introduction to the results seminar, Mika Lasanen
According to industry estimations, volume of wireless data communication will be at least 1000 times bigger and there will be at least 100 times
more wireless communicating devices in year 2020 than in 2010. At the same time, society’s dependency on the wireless communication
infrastructure is increasing.
The goal of the VTT’s innovation program is to develop wireless communication solutions for infrastructures and mobile broadband when
going towards 5G. The key goal is to create concepts and technologies to remarkably improve robustness, interoperability, energy efficiency
and capacity of wireless networks. Towards the thermal noise death of Moore’s law: Implications to telecommunication systems, Aarne Mämmelä
Moore’s law for charge-based electronics was originally presented in 1965 and modified in 1975. The law is in fact not a natural law, but a
prediction that is based on the idea that the energy efficiency of a logic operation has improved exponentially by a factor of 100 each decade.
During the next ten years the energy efficiency will improve only by a factor of ten since the thermal noise and the static power will cause a
limitation to the energy efficiency. It is expected that Moore’s law for charge-based electronics will eventually stop in the beginning of 2020’s.
In this talk we discuss what can be done in this situation.
Testbed for adaptive mesh networking using mobile robots, Paul Kemppi & Matias Elo
Wireless mesh networks rely on dynamic mechanisms when managing the mesh nodes. In this demonstration we will show utilisation of indoor
mesh network repairing using a mobile node with localisation capabilities. Similar advanced management functions can be applied outdoors
using industrial machinery, or even automatically controlled flying vehicles.
Interworking of communication and electricity networks, Seppo Horsmanheimo, Lotta Tuomimäki, and
Niwas Maskey
The demonstration presents a tool used for analysing interdependencies between communication and electricity networks in urban and rural
areas. The system facilitates network structure, propagation environment, network planning, and measurement information from coexisting
2G/3G/4G networks. The tool enables to run different types of fault scenarios and to study their impacts on communication and electricity
networks. The goal is to simulate realistic fault situations (e.g. Hannu/Tapani storm), to detect critical points in both networks, and discover
techniques to alleviate faults’ consequences and to speed up recovery of these two critical infrastructures.
Networking Resource Restricted Small Devices, Jyrki Huusko
The demo shows the advanced IoT gateway solutions with complex event processing system in sensor data collection, Constrained Application
Protocol (CoAP) for data communication, hierarchical CoAP mirror server architecture for scalable data storage and retrieval, and semantic
real-time reasoning based on sensor data. Our demonstration presents the hierarchical IoT system topology using the cloud based resource
instantiation with CoAP. The target is to improve the scalability of IoT infrastructure and energy-efficiency with minimizing network usage in
local wireless sensor networks by utilizing local Mirror Servers and complex event processing algorithms, and to introduce the hierarchical
multi-protocol gateway architecture with two-tier complex event processing and reasoning solutions. The demo presents also a semantic
reasoning engine based on real-time sensor data, ontology, and application specific rules. In this demo, we show a security system which can
send alerts to users if physical objects are moved, temperature is changed, or lighting is changed. Switch ON/OFF buttons can also manually
send/cancel alarms.
End-to-end mobile video QoE management, Markus Luoto and Tiia Ojanperä
Demonstration shows an adaptive HTTP video streaming platform supporting mobility and cognitive management via the Distributed Decision
Engine (DDE). The system makes use of cognitive decision techniques and the DDE framework for facilitating autonomous and optimized video
adaptation and handover decision-making in heterogeneous multi-access networks. The goal of the optimization is to enhance the Quality of
Experience (QoE) for the video user in an end-to-end scope.
Zero Power Sensor Network: Wireless sensing without batteries, Pekka Pursula
The Zero Power Sensor Network is a solution for intelligent sensing: sensing is wireless and passive. There are no bateries or cables. Yet, the
concept enables reading many sensors at the same time with communication distances of several tens of meters, high speed, high accuracy,
and compilancy with the frequency regulations. It is a revolutionary solution for the full deployment of the Internet of Things and the Industrial
Internet. The concept also finds direct applications to the medical, environmental and housing sectors. The concept received the 2013 FIMECC
prize award, emphasizing the high potential of the Zero Power Sensor Network concept for passive wireless sensor networks.
