A didactic but dated OS for embedded systems **Rating:** 3.0/5.0 stars **Reviewed by:** Victor C. | Senior Researcher - Networked Embedded Systems, Small-Business (50 or fewer emp.) **Reviewed Date:** November 24, 2020 **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. **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. **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. **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". ### 2. Overall good experience, nice idea with wiring and support for multiple devices **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Research | Small-Business (50 or fewer emp.) **Reviewed Date:** January 01, 2021 **What do you like best about TinyOS?** 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 **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. **What problems is TinyOS solving and how is that benefiting you?** Used for wireless sensor network of shimmer devices for medical data acquisition ### 3. Developing Wireless Network Sensor with TinyOS was easy and useful **Rating:** 3.0/5.0 stars **Reviewed by:** Christian H. | Software Product Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** November 02, 2020 **What do you like best about TinyOS?** Developing with TinyOS is very simple and flexible **What do you dislike about TinyOS?** As many other codes it has some limitations. **Recommendations to others considering TinyOS:** Using TinyOS is simple and efficient. Consider using it for ressearch and development in your projects **What problems is TinyOS solving and how is that benefiting you?** Simulation of real wireless sensor networks to find the data traffic and network efficiency ### 4. Academia Friendly **Rating:** 2.5/5.0 stars **Reviewed by:** Verified User in Oil & Energy | Small-Business (50 or fewer emp.) **Reviewed Date:** December 09, 2020 **What do you like best about TinyOS?** It has a very tidy construct for setting up different node systems, which makes it easy to implement various protocols **What do you dislike about TinyOS?** User startup guide is sometimes confusing **What problems is TinyOS solving and how is that benefiting you?** Setting up a communication protocol with handshake. It has great benefits in analysing race conditions ## TinyOS Discussions - [Nothing](https://www.g2.com/discussions/35518-nothing) - 1 upvote - [View TinyOS pricing details and edition comparison](https://www.g2.com/products/tinyos/reviews?filters%5Bnps_score%5D%5B%5D=3§ion=pricing&secure%5Bexpires_at%5D=2026-08-10+19%3A04%3A13+-0500&secure%5Bsession_id%5D=7979a5af-df6e-494c-b02e-7e6c03ff7f2a&secure%5Btoken%5D=6f780c08f5ea13a7ddd78bd605dfef45a637b0f9b6664ad5221a155019f66551&format=llm_user) ## TinyOS Features **Security** - Access Controls - Network Security - Compliance - Cryptography ## Top TinyOS Alternatives - [Windows for IoT](https://www.g2.com/products/windows-for-iot/reviews) - 4.3/5.0 (19 reviews) - [Amazon FreeRTOS](https://www.g2.com/products/amazon-freertos/reviews) - 4.1/5.0 (12 reviews) - [Nucleus RTOS](https://www.g2.com/products/nucleus-rtos/reviews) - 4.2/5.0 (19 reviews)
