Building wireless sensor network applications is a challenging
task, and it has become apparent that it is crucial for many
sensor networks to be able to load or update the application
after deployment. Since communication is a scarce resource
and costly in terms of energy, it is important to minimize code
size when reprogramming WSNs in the field. This paper introduces
SensorScheme as a novel interpreted WSN platform for
dynamically loading sensor network applications. It is based
on the semantics of the Scheme language and is equipped with
high-level programming facilities such as higher-order functions,
garbage collection, communication by automatic marshalling
of data items, and co-routines to implement blocking
I/O operations. SensorScheme makes efficient use of the little
available memory in WSN nodes, uses a very compact program
notation during wireless transmission, and provides a safe
interpreted execution environment, preventing malfunctioning
programs from crashing the device. We illustrate the use of
SensorScheme and evaluate its code compactness and energyefficiency.
