One Comparison of WSN Operating Systems

Wireless sensor networks are rapidly developing, field becoming more demanding and complex over the time. Each device is getting more responsibilities, sensing different environmental data, communicating with neighboring nodes, routing traffic, optimizing energy efficiency. Different communication stacks may be available on the node as well. Therefore, in order to support many tasks, different protocols and data exchange, it is necessary to transtion from a bare metal application, towards operating system and frameworks. This paper present an overview of available operating systems suitable for wireless sensor network microcontrollers (MCD). Key aspects of wireless sensor networks operating system are presented, and later are used to compare and evaluate available open-source OSs.
