The Contiki Operating System
Contiki is an open source, highly portable, networked, multi-tasking operating system for memory-constrained embedded systems. It includes a multitasking kernel, a TCP/IP stack and a set of application programs, and a low-power radio communication stack. It is written in C and designed to be very small: it runs comfortably in a few kilobytes of RAM.
