The capabilities of a sensor network are strongly influenced by the operating system used on the sensor nodes. In general, two different sensor network operating system types are currently considered: event driven and multi-threaded. It is commonly assumed that event driven operating systems are more suited to sensor networks as they use less memory and processing resources. However, if factors other than resource usage are considered important, a multi-threaded system might be preferred. This paper compares the resource needs of multi-threaded and event driven sensor network operating systems. The resources considered are memory usage and power consumption. Additionally, the event handling capabilities of event driven and multi-threaded operating systems are analyzed and compared. The results presented in this paper show that for a number of application areas a thread-based sensor network operating system is feasible and preferable.

“…This additional overhead translates to an increase in energy consumption as less idle-time is available for sleep periods. However, as shown in [3] this processing overhead can be reduced to acceptable levels. Third, the TinyMOS solution has a larger memory footprint.…”

“…The resulting TinyMOS system has a large memory footprint (see Section V). Many context switches (for example, introduced by time-slicing) create a significant processing overhead (see [3]). In addition, TinyOS and MANTIS programming semantics are mixed which makes TinyMOS usage difficult.…”

“…These context switches must be implemented carefully to avoid a significant increase in system overhead and energy consumption. Our previous research [3] on optimizing preemptive scheduling for the multi-threaded MANTIS system highlighted that it is of paramount importance to reduce the number of context switches. With this design requirement in mind the PL scheduler avoids preemption where possible using two different principles.…”

Event-driven operating systems such as TinyOS are the preferred choice for wireless sensor networks. Alternative designs such as MANTIS following a classical multi-threaded approach are also available. Event-based systems are generally more energy efficient than multi-threaded systems. However, multi-threaded systems are more capable than event-based systems of supporting time critical tasks as task preemption is supported. Timeliness can be traded for energy efficiency by choosing the appropriate operating system. In our recent work we have shown that the multi-threaded system MANTIS can be modified to be as energy efficient as TinyOS. As a result, the modified MANTIS can be used to fit both sensor network design goals of energy efficiency and timeliness. This solution is not considered optimal as most existing sensor network applications and software libraries are developed for TinyOS. Therefore, we present a TinyOS modification that adds preemption while retaining the existing TinyOS structure and features.

This paper presents a technique to integrate energyaware real-time scheduling into sensor node platforms from the perspective of the combined periodic (or time-bounded) and aperiodic (or time-unbounded) scheduling policy. In the scheduling policy, the first objective is to meet the timing constraints of periodic tasks as well as to improve the response time of aperiodic tasks. The second objective is to minimize the energy consumption in a battery-powered sensor node without missing the timing constraints of periodic tasks. Experiments showed that the proposed scheduling technique achieved efficient performance in terms of the minimal deadline miss ratio of periodic tasks, a fast average response time of aperiodic tasks, and low power consumption.
