What is TinyOS ?

TinyOS is an open source and free operating system under BSD license targetting low-power wireless devices, such as those used in sensor networks, ubiquitous computing, personal area networks, smart buildings, and smart meters. Fundamentally, it is a work scheduler and a collection of drivers for microcontrollers and other integrated circuits commonly used in wireless embedded platforms.

Programming languages

TinyOS applications are written in the programming language nesC, a dialect of the C language optimized for the memory limits of sensor networks. Its supplementary tools are mainly in the form of Java and shell script front-ends.
