TinyOS-New Trends, Comparative Views, and Supported Sensing Applications: A Review

The wireless sensor network (WSN) is an interesting area for modern day research groups. Tiny sensor nodes are deployed in a diversity of environments but with limited resources. Scarce resources compel researchers to employ an operating system that requires limited memory and minimum power. Tiny operating system (TinyOS) is a widely used operating system for sensor nodes, which provides concurrency and flexibility while adhering to the constraints of scarce resources. Comparatively, TinyOS is considered to be the most robust, innovative, energy-efficient, and widely used operating system in sensor networks. This paper looks at the state-of-the-art TinyOS and the different dimensions of its design paradigm, programming model, execution model, scheduling algorithms, concurrency, memory management, hardware support platforms, and other features. The addition of different features in TinyOS makes it the operating system of choice for WSNs. Sensing nodes with TinyOS seem to show more flexibility in supporting diverse types of sensing applications.
