A Benchmarking Tool for Wireless Sensor Network Embedded Operating Systems

Abstract—The emergence of the technology of Wireless Sensor Networks (WSNs) has lead to many changes in current and traditional computational techniques in order to adapt to their harsh and scarce requirements. A WSN consists of sensor nodes with wireless communication abilities that allow them to form a network. New system architectures have emerged to overcome sensor network limitations. Each architecture follows one of the two traditional design concepts, event-driven or thread-driven design. Although event-driven systems were assumed to generally perform better for embedded systems, tests have shown that event-driven systems tend to save more energy and space, while the thread-driven systems provide more concurrency and predictability, hence creating a tradeoff depending on the requirements of the application at hand
