  • The problem is that to build applications on top of these devices we still need to learn a 100 different systems and APIs. Our thesis: how do you enable business to create applications on top of eco-systems of sensor networks and embedded devices.
  • Thus, we suggest creating a Web of Things as an alternative. We basically consider sensor nodes as nodes of the Internet and make them universally accessible over HTTP like the Web is. We do this by: Having IP connectivity (IPv6 Lowpan) Having the nodes (or a gateway) embedding a Web-Server Modeling services as resources.
  • Easy to program, create new stuff Browse and use the IoT 1 or 2.0
  • The first step is to get the Sensors connected to the Internet (!= Web, the Internet is the underlying network! Not the application layer). This can be achieved in two ways: Direct connectivity by using for instance IPv6 Lowpan, i.e. the Ipv6 protocol for resource constrained devices. More and more sensor networks (e.g. Arch Rock nodes, etc.) For non-IPv6 nodes we propose the concept of smart gateways. Smart gateways are small pieces of software that can be installed on emedded devices such as Wireless routers or NAS (Network Access Storage). Their goal is to understand the proprietary protocols and APIs of embedded devices (e.g. BT) and to « translate » offer access to these devices through uniform REST APIs.
  • Discover a Sun Spot, see the Web UI, browse it.
  • Discovery, embedded WebServer Access the Ploggs functionality directly from the browser.
