Contiki OS Projects

Contiki OS Projects develop novel ideas in the field of resource-constrained Internet of Things (IoT). Contiki is an Operating System that aids in Low Power Wireless Devices (most likely Sensors) under the BSD license (i.e.) Open Source. As we see nowadays, most of the real-time cases use devices with lightweight (in Memory, Power, and Bandwidth) hardware. In order to model and test these cases, one wants more vesting tools (i.e.,) Contiki OS. 

We suggest Contiki OS for IoT Projects. But Why? The reasons are below,

• Allows Internet Protocol Suite (TCP/IP with IPv6)
• Has Multitasking Kernel
• Supports Virtual Network Computing 
• Assist with Windowing System and GUI
• Aids through Personal Web Server

   In exact, Contiki OS Projects can use any of the IP protocols like uIP, uIPv6, Rime, and CoAP. Also, it is too lightweight that runs in a few kilobytes within a space of 30KB along with the GUI. 

Important Contiki OS Modules for Data Transmission

• Single-hop Reliable Unicast
  • Uses runicast.c and runicast.h files
  • Supports packet retransmissions
• Best-effort Multi-hop Forwarding 
  • Uses rmh.c and rmh.h files
  • Route Setup by route_add() 
• Single-hop Reliable Bulk Data Transfer
  • Uses rudolph2.c and rudolph2.h files
  • Transmission in 2 Channels (for NACK)
• Mesh Routing
  • Uses mesh.c and mesh.h files
  • Driven by mesh_callbacks structure

   In the view of IoT, routing is the most vital part since it decides the overall performance of the network. Thus, we provided routing-related modules. In the same way, Contiki has more modules as well as libraries to explore. 

HOW WE BUILD A CONTIKI SYSTEM? FLOW FOR IOT ROUTING

Build Targets

• Makefile.include
• Makefile.$(Target)
• Makefile.$(CPU)
• Makefile.$(APP)

Configure Network

• Implement Protocol
  • ROUTE_CONF_ENTRIES
  • ROUTE_CONF_DEFAULT_LIFETIME

   On the basis of the above modules, we can build a routing protocol in Contiki OS. Likewise, it has distinct modules for MAC (e.g., ContikiMAC), Broadcasting, and so on. To mention that Contiki OS has the internal systems such that it copes with all needs of IoT MQTT projects.

INTERNAL SYSTEM OF CONTIKI

• Contiki Processes and Timers
• Memory Allocation
• Input and Output ports
• Clock Libraries
• File Systems and Interface
• Communication Power Accounting
• Multithreading
• And also Protothreads

   When we talk about Contiki OS Projects, we have to look over the Cooja simulator. While working on Contiki, it aids in simulations by Cooja. In detail, Cooja is a Contiki level tool that specifies to simulate the Contiki motes. All in all, we can end up the project with the expected quality. 

   Till now, we have seen the core outline of Contiki OS. Apart from this, Contiki OS also allows external platforms to connect with it. For sure, we can link our project with any of these platforms.

CONTIKI ADMISSIBLE HARDWARE PLATFORMS

• RZRAVEN LCD 3290p
• The ESB Embedded Sensor Board
• The Tmote Sky Board
• RZRAVEN USB Stick 
• The Modular Sensor Board

   On top of the above info, we like to see the sights about Contiki NG (i.e.) Contiki for Next-Generation internet of things projects. It covers TSCH and 6TiSCH, which are special on IIoT standards too. At this time, we have 10K+ claims to do projects in this tool. 

   By all means, doing your project in Contiki is the ease and also in effect. It demands your patient to learn, along with better supervision. If you feel that your project is out of control, then take our help without a doubt. We will raise it to the utmost peak within a short period. Why are you still waiting?
