In recent years, ubiquitous systems are reshaping the way people live, work, and play. Thereby, services application to guarantee various requirements of users become increasingly sophisticated and complicated,such ubiquitous sensor network platforms must use real-time operating systems with time determinism. This paper presents a real-time operating system, called SenOS, designed for ubiquitous sensor networks. We present some of the features that make SenOS appropriate especially for small, low-cost micro-controllers typically found in ubiquitous sensor networks and introduce 8 priority levels for adopting sensor platforms and task ports to decrease inter-task communication overhead. Also, we propose that it could adapt the dynamic power management scheme for energy savings. The experimental results show that SenOS with 3.8KB footprint sizes is quite efficient for a sensor network, both in terms of memory requirements and system performance.
