I need OS or RTOS for an IOT

Hello i need a good Operating system or Real Time Operating System for IoT project.
I need a suggestion of an OS or someone that can work on it.

Low-level like C library: FreeRTOS
concurrency and IPC by 1 to 1 stream/message passing, n to 1 asynchronous direct process signal/event, n to n fixed size message queue (pipe), signals and semaphores

High-level like Linux+KDE: QNX
concurrency and IPC by n to 1 synchronous message passing and n to 1 asynchronous signal; Qt or HTML5 for GUI

What are you planning with regards to an IoT project?


I only need an is that will run my software and also start my WiFi and SIM card network.
