Contiki – a lightweight operating system for WSN

What is Contiki ?

As wirelles sensor networks are composed of large numbers of tiny sensor devices .

Facts :

* Contiki is an open-source OS for sensor network nodes

- Originally created by Adam Dunkels in 2003

- Implemented in C

- Developers : SICS, SAP AG, Cisco, Atmel, NewAE , TU Munich.

- Highly portable : MSP430, AVR, HC12, Z80, 6502, x86

- Simulation environment for BSD/Linux/Windows/Mac

- Protocol stack configuration customizable

- Require a complete binary image (operating system, libraries and the actual application/s)

-Integrates uIP small TCP/IP stack that makes it possible for Contiki to communicate over the Internet

- The Contiki kernel uses a single shared stack

- Contiki provides IP communication, both for IPv4 and IPv6

- Compile on a 30kbytes of RAM.

- is a even -driven system

Concerning application in Contiki we can do telnet session , also thinking to nodes in WSN we are speaking about web
