| Overview |
A main
challenge to developing applications for wireless embedded
systems is the lack of run-time visibility and control. We
developed a tool suite called Marionette that provides an
interpreter through which the network operator can remotely call
the node's functions, read and write its variables, and access
its enumerations and data structures. This interactive and
scriptable environment allows the developer to seamlessly trade
off between between writing application logic on the PC for
simplicity and debugging or writing it on the nodes for
increased efficiency. This greatly eases the development
process and we have shown that this tool suite can reduce code
size in several existing applications by up to 75%. Marionette
is actively being used for development on several testbeds of up
to several hundred nodes. Marionette builds upon my earlier
work on the Matlab/TinyOS
development environment, which has been in the main TinyOS
distribution. | |||

| Software | The code for Marionette is publicly available and is part of the standard tinyos-1.x software distribution. | |||
| Documentation | Documentation for installing and using Marionette can be found on a public wiki, which includes screenshots. Installation of jpype can be tricky. To try Marionette without going through the installation process, try using the live CD called Xubuntos, which lets you boot into a working tinyos environment. , | |||
