IoT Contiki OS – Top 5 Communication Components in Contiki

1. Objective

In the last IoT tutorial, we discussed Eclipse IoT and now we will discuss Contiki OS in IoT System. Moreover, we will cover the functions, features, and applications of Contiki OS. In addition, we will see communication components of Contiki Internet of Things.
So, let’s start with IoT Contiki OS.

2. What is Contiki Operating System?

IoT Contiki is an OS much like Microsoft Windows and Linux. However, for a completely precise reason and in particular focused on ‘matters’ within the IoT. Various functions of an OS consist of software/technique control, useful resource manipulate, memory management and verbal exchange management. The goal of Contiki OS is to fulfill requirements of the smallest gadgets together with clever dirt. Things need to be able to talk some bits of information to one another.
IoT Contiki is an open source software assignment with the vision to create a minimalist and running OS for huge deployment. This challenge has damaged many myths about the smallest footprint wherein an OS can be stored and made to function. One such software program is the uIPv6—global’s smallest IPv6 stack—which is incorporated into Contiki OS.

3. Features and Functions of Contiki OS

Contiki OS comes with a wealthy set of capabilities which might be device and programmer friendly. It may run on gadgets inclusive of 8051 SoC to ARM-powered gadgets. Ports are on different platforms together with Arduino and Atmel. While popular compliance may be needed to interoperate with public networks (together with net), more green and optimized protocols are also supported. One such example is the Rime stack, advanced to optimize the IPv6 protocol.
Contiki OS comes with a lot of documentation aside from well-documented code. There are also community boards wherein energetic discussions take place.
Running machine features encompass:

Contiki OS helps memory block allocation and trendy ‘C’ style allocation with malloc( ). The idea and implementation of ‘protothreads’ have introduced retaining the low gadget requirements in thoughts. ‘protothreads’ are C-language-based totally implementation minimizing the overhead of multi-threaded programming.

Besides, Contiki OS supports both IPv4 and IPv6 implementations, which consist of TCP, UDP and HTTP protocols. The IP stack is requirements-compliant. The OS additionally helps low-strength editions which includes 6LoWPAN.

No longer all gadgets as a part of IoT have the luxury of chronic garage including Flash. However, for such gadgets, Contiki OS affords guide through the espresso Flash file system.

4. Applications Of Contiki OS

There are more applications, comes in a package as a part of Contiki OS. Those include a small net browser, net server, calculator, shell, telnet patron and daemon, e-mail customer, the vnc viewer, and ftp.
Contiki OS additionally provides mechanisms to measure strength for various operations that help developers produce programs that are power sensitive. Software package deal additionally comes with a UNIX-style shell for interacting with OS and debugging.

5. Communication Components in Contiki OS

Contiki OS supports protocols for IoT −

a. 6LoWPAN − This stands for IPv6 over low-energy wi-fi personal place networks. It provides compression era to guide the low information charge wi-fi wished by means of devices with restrained resources.

b. RPL− This distance vector IPv6 protocol for LLNs (Low-Strength and Lossy Networks) permits the quality viable path to be discovered in a complicated network of devices with various capacities.

c. CoAP− This protocol helps communique for simple devices, generally gadgets requiring heavy remote supervision.

d. uIP (for IPv4)− This TCP/IP implementation is used for 8-bit and sixteen-bit microcontrollers.

e. uIPv6 (for IPv6) − This is a fully compliant IPv6 extension to uIP.

So, this was all about IoT Contiki Operating System Tutorial. Hope you like our explanation.

6. Conclusion

Hence, today we learned IoT Contiki operating System with its application. In addition, we discussed Functions and Features of Contiki Operating System. At last, we saw Contiki Communication Components. Furthermore, if you have any doubt feel free to ask in the comment section.
