TinyOS: An Operating System for Sensor Networks
We present TinyOS, a flexible, application-specific operating system
for sensor networks. Sensor networks consist of (potentially)
thousands of tiny, low-power nodes, each of which execute concurrent,
reactive programs that must operate with severe memory
and power constraints. The sensor network challenges of limited
resources, event-centric concurrent applications, and low-power
operation drive the design of TinyOS. Our solution combines flexible,
fine-grain components with an execution model that supports
complex yet safe concurrent operations. TinyOS meets these challenges
well and has become the platform of choice for sensor network
research; it is in use by over a hundred groups worldwide,
and supports a broad range of applications and research topics.
We provide a qualitative and quantitative evaluation of the system,
showing that it supports complex, concurrent programs with very
low memory requirements (many applications fit within 16KB of
memory, and the core OS is 400 bytes) and efficient, low-power
operation. We present our experiences with TinyOS as a platform
for sensor network innovation and applications.
