Communicating and Interacting with Embedded Web Resources

A Research Project of the Distributed Systems Group

With the standardization of Internet technology for constrained networked embedded devices, a vision of pervasive computing is becoming reality: Everyday objects are getting "smart" through sensing, actuation, and computing power and interconnected in an Internet of Things. This project is devoted to design a Web-like application layer for the most resource-constrained devices and to make programming of Internet of Things applications significantly easier.

The key incentives for the proposed architecture are full Web integration, intuitive APIs, decoupling of infrastructure and applications, and end-user programming. These can be achieved by separating the application logic from the device firmware. The thin server architecture—analog to the thin client, which is only equipped with the necessary interfaces to interact with the user—relieves embedded servers from the burden of application logic and rather utilizes them as wrappers for the sensors and actuators of the smart objects.

We study this system architecture by means of a prototypical implementation. The low-end devices are connected to the Internet using the 6LoWPAN protocol, an adaption layer for normal IPv6 to be used over low-power communication links. On top, we use the leight-weight Constrained Application Protocol (CoAP), a HTTP-like protocol for machine-to-machine communication, which is currently drafted by the IETF. In this course, we published three different open-source implementations:
