Senior Researcher - Networked Embedded Systems Small-Business (50 or fewer emp.) 11/24/2020 "A didactic but dated OS for embedded systems" 3/5 What do you like best about TinyOS? TinyOS is developed in the nesC language which is quite different from C. Instead of the traditional C application that has a main function from which the entire functionality develops, TinyOS applications are more similar to component-orientated systems. An application is a collection of components that implement interfaces and are connected through those interfaces. In this way TinyOS makes the developer more aware of the interaction between components (hardware and software) than if developing a sequential C application. Review collected by and hosted on G2.com. What do you dislike about TinyOS? Development in TinyOS is difficult to grasp for someone schooled in C or Java, and for this reason it has lost momentum in favour of more traditional C-based real time OSs such as Contiki, Riot, etc. Review collected by and hosted on G2.com. Recommendations to others considering TinyOS: TinyOS is dated. It hasn't received any support for years now. The team that was maintaining TinyOS has now moved on to Tock OS, and Contiki OS is the preferred OS for embedded systems research nowadays. Review collected by and hosted on G2.com. What problems is TinyOS solving and how is that benefiting you? The main purpose of TinyOS is research and development of embedded systems applications. I have used TinyOS to develop Medium Access Control protocols, routing protocols, security protocols, power management algoirthms, and holistic security architectures for low power embedded devices. I have also developed or contributed to the development of file system drivers. I have implemented different types of applications, from multi-sensorial falls detection applications to an application that plays "Jingle bells". Review collected by and hosted on G2.com.

Overall idea and environment idea is great. Love the nesc idea of wiring, this makes the system easier to connect big components while maintaining the low level of access with c Review collected by and hosted on G2.com. What do you dislike about TinyOS? Debugging might be hard or at least not well documented. More project examples could be created as documentation for quick start.
