Besides the currently realized applications, wireless sensor networks can be put to use in logistics processes. However, current WSN software platforms cannot provide the flexibility and safety needed. This paper presents SensorScheme, a runtime environment based on semantics of the Scheme programming language, used to realize a logistics scenario. SensorScheme is a general purpose WSN platform, providing dynamic reprogramming, memory safety (sandboxing), blocking I/O, marshalled communication and compact code transport. We illustrate the use of our platform and provide experimental results that show its speed of operation and energy efficiency.
