“…In [9], Choi et al suggested a global device driver architecture dedicated to multithreaded sensor network operating systems. This architecture provides also three kinds of driver models (offering several trade-offs between performance and complexity), and some global operating system services to control shared access and energy consumption through a so-called device manager.…”

In embedded systems, controlling a shared resource like the bus, or improving a property like power consumption, may be hard to achieve when programming device drivers individually. There is a need for global resource control, taking decisions based on a centralized view of the devices' states. In this paper, we study power consumption in sensor networks, where the nodes are small embedded systems powered by batteries. We concentrate on the hardware/software architecture of a node, where significant gains can be achieved by controlling the consumption modes of the various devices globally. The architecture we propose involves a simple adaptation of the application level, to communicate with the hardware via a control layer. The control layer itself is built from a set of simple automata: the drivers of the devices, whose states correspond to power consumption modes, and a controller that enforces global properties. All these automata are programmed using a synchronous language, whose compiler performs static scheduling and produces a single piece of C code. We explain the approach in details, demonstrate its use with either Contiki or a traditional multithreading operating system, and report on our experiments.

“…The ICEM's architecture leads to a decentralized energy and resource management scheme, split among driver classes. Choi et al [2008] suggested a global device driver architecture dedicated to multithreaded WSN OSes. This architecture also provides three kinds of driver models (offering several trade-offs between performance and complexity), and some global operating system services to control shared access and energy consumption through a device manager.…”

In embedded systems, controlling a shared resource like a bus, or improving a property like power consumption, may be hard to achieve when programming device drivers individually. In this paper, we propose a global resource control approach, based on a centralized view of the devices' states. The solution we propose operates on the hardware/software interface. It involves a simple adaptation of the application level, to communicate with the hardware via a control layer. The control layer itself is built from a set of simple automata: the device drivers, whose states correspond to functional or power consumption modes, and a controller to enforce global properties. All these automata are programmed using a synchronous language, and compiled into a single piece of C code. We take as example the node of a sensor network. We explain the approach in details, demonstrate its use and benefits with an event-driven or multithreading operating system, and draw guidelines for its use in other contexts.
