Open & Free All the technical information is publicly available. Source program is provided. Anyone can use TRON for free. 14 7 2011/10/28 Ultimate Goal of TRON Project ■ The use of embedded system technology for the future applications of the IoT. ■ In such applications computing nodes with sensors and actuators, i.e., embedded system nodes, are networked together to offer advanced services. 15 The Vision of Future Computing TRON Project since 1984 ■ “…most machines in our surrounding environment including pieces of furniture will use computers. It is conceivable that 100 computers for a man will exist.” … Ken Sakamura: “The Objectives of TRON Project,” in TRON Project 1987, Springer-Verlag, 1987, pp. 3-16. 16 8 2011/10/28 TRON Project ■ Joint effort of Industry and Academia ■ Open Approach: make the results widely available ■ Many participants from outside Japan ■ Making the necessary components ourselves ITRON specification OS: specification and sample implementation T-Kernel: specification AND a single source repository of official implementation(!) ■ Difference with ARTEMIS(?) 17 International Cooperation ■ EU FP7 CASAGRAS2 project ■ Cooperative project in WUXI (China) 18 9 2011/10/28 International Cooperation ■ Finland Tekes joined T-Engine Forum. Finnish delegation including the minister of transportation and communication Ms. Linden visited. The MOU has been signed with VTT. 19 T-Engine Forum http://www.t-engine.org/ 20 10 2011/10/28 T-Engine Forum ■ An NPO to promote TRON Project ■ Chair: Dr. Ken Sakamura ■ Distribute specification, source code for RTOS free T-Kernel, T-Kernel2.0, uT-Kernel, etc. ■ Operates uID Center under its umbrella ■ Close to 300 members world-wide government, big business, SME, academia ■ A very similar function in private sector, to that of ITEA2 plays. From the web page of ITEA2 (emphasis mine) : We stimulate and coordinate industry-driven, business-oriented, pre- competitive R&D by bringing together partners from industry, universities and research institutes in strategic projects. 21 Striking Similarity with ARTEMIS SRA2001 ■ Strategic Research Agenda 2011 (SRA2011) ■ Very similar to what TRON Project envisions ■ Inevitable (?) convergence due to shared background of industrialized nations. Graying of society Energy crunch Search for clean and safe energy sources Smart cities, comfortable and eco-friendly living environment Safe and efficient transportation (ITS) 22 11 2011/10/28 Earthquake’s Impact 23 Earthquake Has… Hastened the pace of certain R&D activities Placed different emphasis on different topics Example: Energy saving 24 12 2011/10/28 Energy Saving: the Application of the IoT, a Case in Point ■ Embedded systems can NOT produce energy, but they can help the efficient usage of precious energy sources and reduce waste. ■ Even BEFORE the earthquake, Japanese government has made efforts to reduce CO2 emission by agreeing to Kyoto Protocol. About 70% of electricity in Japan is produced by burning oil/gas/coal, etc. 25 Reducing CO2 Emission and Energy Waste ■ Already much has been done in the industry sector. ■ The remaining squeeze has to be done in the ordinary households and public places. ■ Traditional Approaches The use of energy efficient appliances and devices Using sensor networks to monitor usage and human movements to turn off non-essential or unused devices The use of energy-efficient parts for devices such as CPUs, sensor network nodes, LEDs, TVs, air- conditioners, etc. to begin with ■ Reducing energy usage at homes 26 13 2011/10/28 Visualization of Energy Usage ■ Important element to reduce energy usage Such visual data motivates people to strive for more reduction of electricity usage if possible. ■ Various old and new approaches have been consolidated into TRON Smart House Approach. 27 TRON Smart Houses ■ Have implemented these energy saving features in a series of TRON Smart Houses. The first one built in 1989. • The first large scale house built using the concept of today’s ubiquitous computing experiment. The second one in 2004. The third in 2009. ■ TRON House is the ultimate example of ubiquitous computing based on uID architecture. 28 14 2011/10/28 TRON House ■ How technologies affect the society in general: living style, houses, cities, and environment(s). 29 Cooperative Action of Nodes in Smart House 30 15 2011/10/28 Eco-Friendliness: PAPI, House of Sustainability 31 New Electricity Source: An Automobile! ■ A renewed attention or new focus on the following facts: TOYOTA Prius, a hybrid car, can generate electricity. The same car also acts as a large rechargeable battery. 32 16 2011/10/28 VIDEO PAPI 33 From Houses to Cities 34 17 2011/10/28 Projects All over Japan (slightly old map) 35 Tokyo Ubiquitous Technology Project in Ginza infrared marker passive RFID tag RF Active Tag and ucodeQR 36 36 18 2011/10/28 Tokyo Ubiquitous Technology Project in Ginza: in Normal Times ■ The same infrastructure is used for sight-seeing, shop/restaurant guide, helping the physically- challenged in normal times 37 Tokyo Ubiquitous Technology Project in Ginza: in EMERGENCY ■ The same infrastructure is used for Aid and relief such as • evacuation route guidance, • locating family members, etc. in times of disasters such as seasonal typhoons (name of seasonal storms in the north western Pacific) and earthquakes 38 19 2011/10/28 i-Box ■ i-Box: an information Kiosk that can talk to the global Internet via satellite when the ground-based communication network is destroyed after an earthquake. 39 Have We Prepared for a Big Earthquake Enough? ■ Not enough We have performed feasibility studies and pilot projects in selected areas of Tokyo. But it has not been wide-spread to the rest of Japan. ■ Very regrettable ■ However, a satellite communication unit developed in the R&D efforts WERE used in the communication network immediately after the earthquake and was found very useful (!) 40 20 2011/10/28 Embedded Systems as Society’s Neural Backbone 41 SRA2011: Analogy of the Embedded Systems in Society as Neural Backbone ■ A good observation with which we agree completely! ■ But now an interesting observation or question: Is the safety or well-being of the whole body (whole society) in agreement with a particular individual organ (say, a house or a neighborhood) all the time? 42 21 2011/10/28 A Case in Point: Planned Rolling Blackouts ■ The big earthquake in March shutdown many power generation plants, and destroyed the distribution network. ■ An imminent large-scale blackout was predicted. ■ Initially, electric utility companies introduced “Planned Revolving/Rolling Blackouts” to avoid a large scale blackout by cutting electricity in some areas by rotation to reduce the total electric consumption. ■ The country coped with the electricity crunch by shifting the opening days and working hours of factories and offices eventually during the summer of 2011. An AMAZING FEAT! 43 Problem with the Planned Rolling Blackouts: Crude Control ■ The control was done very coarsely initially. ■ A large town or an area was the unit of control. ■ Areas with big hospitals with large number of beds were spared from the blackouts. ■ But, Life and death problems in blackout areas, of houses or small hospitals with sick people in the bedrooms with electric medical aid that cannot withstand prolonged power blackouts.

  • Cpaas.Io: an Eujapan Collaboration on Open Smart City Platforms
    CPaaS.io: An EUJapan Collaboration on Open Smart City Platforms Noboru Koshizuka (The University of Tokyo) Stephan Haller (Bern University of Applied Sciences) Ken Sakamura (Toyo University) Abstract Data-driven cities and governments rely significantly on data collec- tion, management, and distribution platforms. In this article, we intro- duce CPaaS.io, a collaborative project between Japan and the European Union with the goal of establishing common smart city platforms for de- ployment in real smart city use cases. 1 INTRODUCTION Today, data are crucial to the functioning of society. In fact, it is sometimes said that the most competitive area in information and communications technology (ICT) is not algorithms but data. The ICT National Strategy of Japan known as Society 5.0 proposes a data-driven society in which data help solve problems in the fields of mobility, supply chains, healthcare, and lifestyle to name a few. This will generate further economic growth and increase quality of life. Conse- quently, both in Japan and the European Union (EU), data have been termed the oil of the 21st century. These data come from a variety of sources: the Internet of Things (IoT) and sensors, open government resources, social media, and industry and business repositories, not to mention the wealth of personal information from individual users. These can be obtained, linked, and analyzed to extract valuable intelligence and transform our society for a better future. In the deployment of smart city services, providing a platform for data collection, management, and distribution is crucial.
