Rapid prototyping suite of IEEE 802.15.4-compliant Sensor Networks

This paper presents a toolsuite for rapid prototyping and implementation of real-time applications on Wireless Sensor Networks. The work is motivated by the need to use WSNs in industrial control contexts, where the sampling rate, the workload is much higher than typical current applications of WSNs, and the real-time constraints are much tighter. We present a simulator for early evaluation of the real-time behavior of a WSN application; and a realtime operating system that implement appropriate real-time scheduling policies to allow timing analysis and guarantee timing constraints. We provide a demo based on a simple but realistic network scenario showing that simulation is in agreement with experimental results.
