A component-based, extensible, tiny operating system for wireless networks (CometOS)

The project develops CometOS, a component-based, extensible, tiny operating system for wireless networks. It is written in C++ and highly inspired by OMNeT++'s communication paradigm. It allows the execution of protocols within the OMNeT++ simulation environment as well as on resource-restricted platforms such as wireless sensor nodes.

Key Features are:

- Forces type safety for message types (no type casting necessary)
- Avoids OMNeT++'s boilerplate code for handling messages (timers and gates are directly mapped to callback methods)
- Excellent integration with OMNeT++
- Utilizes the MiXiM framework for wireless channel simulation
- Dynamic memory is not mandatory for running the CometOS core, however, an efficient library for dynamic memory allocation on microcontrollers is provided
- Exploits C++ template programming in order to generate fast code for microcontrollers
- Excellent debugging support
- Supports object-aggregation similar to NS3 for cross-layer support
- Contains template library optimized for sensor nodes (e.g., static/dynamic lists, maps)
- Customizable serialization/deserialization mechanism for airframes
- Intended for a modular/layered protocol design
