TinyOS is an open-source operating system designed for wireless embedded sensor networks. It features a component-based architecture which enables rapid innovation and implementation while minimizing code size as required by the severe memory constraints inherent in sensor networks.
TinyOS’s component library includes network protocols, distributed services, sensor drivers, and data acquisition tools. An open-source OS for the networked sensor regime.
TinyOS for Wireless Embedded Sensor Networks
TinyOS has been ported to over a dozen platforms and numerous sensor boards. A wide community uses it in simulation to develop and test various algorithms and protocols. – Official TinyOS Website
This is a nice OS for a Distributed Industrial Automation Implementation. Data Logging Systems. It is an open-source operating system designed for wireless embedded sensor networks on a BSD license.

The XSM platform integrates an Atmel ATmega128L microcontroller, a Chipcon CC1000 radio operating at 433MHz, a 4Mbit serial ?ash memory, infrared, magnetic, acoustic, photo and temperature sensors, weatherproof packaging, a bootloader, and a “Golden Image” program that incorporates system management, network programming, and low-power listening…..
Contiki is an open source, highly portable, multi-tasking operating system for memory-efficient networked embedded systems and wireless sensor networks. Contiki has been used is a variety of projects, such as road tunnel fire monitoring, intrusion detection, water monitoring in the Baltic Sea, and in surveillance networks.
Contiki – Open Source Multi-Tasking OS
Contiki is designed for microcontrollers with small amounts of memory. A typical Contiki configuration is 2 kilobytes of RAM and 40 kilobytes of ROM.
Contiki provides both full IP networking and low-power radio communication mechanisms. For communication within wireless sensor network, Contiki uses the Rime low-power radio networking stack.
The M-12 module from Redwire is a fast and easy way to create a 6LoWPAN, Zigbee, or general 2.4GHz 802.15.4 device without additional RF design or certifications and without the need for an external host microcontroller. This is a Hardware for Contiki.
Instant Contiki is a complete development environment in a single-file download: a virtual machine with all Contiki software development tools installed. All that is needed to start using and developing Contiki software is the free VMWare Player software, 4 Gb free hard drive space, and the Instant Contiki development environment.

Contiki is an open source operating system for the Internet of Things. Contiki connects tiny, low-cost, battery-operated and low-power systems to the Internet.
The Internet of Things is a collection of technologies that connect things-sensors and actuators-to the Internet, allowing the physical world to be accessed through software.
FreeRTOS is the cross platform de facto standard for embedded microcontrollers. FreeRTOS is designed to be simple and easy to use: Only 3 source files that are common to all RTOS ports, and one microcontroller specific source file are required, and its API is designed to be simple and intuitive.
FreeRTOS – Portable Open-Source Mini RT Kernel
Scaleable real time kernel designed specifically for small embedded systems. FreeRTOS is truly free, even for use in commercial applications. The FreeRTOS license does not pose any risk to your proprietary software.
