  • 1. Design of a Web-based Distributed Location- aware Infrastructure for Mobile Devices WoT2010 @ Percom, Mannheim, Germany 29 March 2010 Vlad Trifa, Dominique Guinard, Philipp Bolliger, Samuel Wieland
  • 2. The Internet of Things ‣ Networked devices everywhere ‣ Tons of different devices ‣ Capabilities/functions ‣ Applications/middlewares ‣ Networking protocols ‣ Internet connectivity ‣ Cheap ‣ Ubiquitous Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 3. WoT: Use the Web to combine heterogeneous mobile devices to create interactive ad-hoc applications! Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 4. Social Web Physical Web Real-time Web Semantic Web Programmable Web Web of Things Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 5. Local: Web-enabled Things? Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 6. RESTful SunSpot ‣ Embedded NanoHTTPD ‣ Talks HTTP (over 802.15.4) ‣ Becomes a Web device ‣ Properties and functions are Web resources, so can be ‣ Browsed ‣ Bookmarked ‣ Shared ‣ But also use twitter, send emails, chat, etc.. D. Guinard, V. Trifa, T. Pham, and O. Liechti. Towards Physical Mashups in the Web of Things. In Proceedings of the 6th International Conference on Networked Sensing Systems (INSS 2009), 2009. Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 7. Example application: Energie Visible Web / Mobile  Interface Gateway  GET http://10.1.1.5/energymonitor/ploggs/* (IP:10.1.1.5) [{ "deviceName": "ComputerAndScreen", "currentWatts": 50.52, "KWh": 5.835, "maxWattage": 100.56 }, Sensors "deviceName": "Fridge", (Ploggs) "currentWatts": 86.28., "KWh": 4.421, Electric  "maxWattage": 288.92 appliances }, {...}] D. Guinard and V. Trifa. Towards the web of things: Web mashups for embedded devices. In 2nd Workshop on Mashups, Enterprise Mashups and Lightweight Composition on the Web (MEM 2009), Madrid, Spain, April 2009. Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 8. Let’s make it global.
  • 9. Infrastructures ‣ We propose an infrastructure for WoT ‣ scalable ‣ flexible ‣ so, must be distributed ‣ The real world is physical. Everything has a location. ‣ You interact with things around you ‣ How to leverage the infrastructure? Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 10. Location Models  Geometric ‣ coordinate reference system(s) ‣ convenient for exact measurements ‣ e.g.: GPS 33°94’, 37°2’  Symbolic ‣ uses identifiers ‣ e.g.: places hierarchy Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 11. Explore the world around you... Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 12. Towards physical mashups ‣ SunSpot gets periodically GET http://here/energymonitor/ploggs/* ‣ Displays the energy consumption in the room ‣ Mobile energy meter ‣ Location-aware ‣ Problem: mapping here/ to current location (bootstrap) ‣ Closest gateway Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 13. RedPin comes to the rescue ‣ Provides room-level accuracy ‣ Uses existing hardware ‣ Very easy to setup and to maintain ‣ Released as open source www.redpin.org Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
  • 14. Take home notes ‣ Intranet of things is nice and useful ‣ But it’s time to think larger ‣ Leverage physical location of nodes of the WoT ‣ Leverage the infrastructure to localize things ‣ Devices don’t need to know where they are Web of Things @ Percom Vlad Trifa - SAP/ETH Zurich
