Automatically Exporting TinyOS Modules as Web Services

As embedded devices become increasingly useful and ubiquitous, it will be important to incorporate them into enterprise applications through Web services and service-oriented architectures. Existing approaches have limitations in terms of either resource consumption or burden on the programmer. In this paper, we present a new framework to automatically export TinyOS modules as Web Services using a resourceefficient architecture, thereby minimizing both resource usage and the burden on the programmer. As a proof of concept, we demonstrate our framework by creating a TinyOS module that can be accessed by both Python and Java clients with no additional code required from the user. We demonstrate that our framework incurs very little RAM, ROM, CPU, or network overhead, even when the node moves between gateway nodes. The techniques used by our framework currently support both TinyOS 1.x and TinyOS 2.x, and the techniques can easily be generalized to support other wireless embedded programming systems.
