What Do You Mean by IoT Contiki

           Through this article, our research professionals have depicted a step at a time process to know about the utilizations of IoT Contiki.

          IoT Contiki is considered as the open source software assignment and it is assistive for the memory block allocation and trendy ‘C’ style allocation along with the malloc( ). In addition, Contiki OS is supportive for the implementations based on IPv4 and IPv6 along with the protocols such as TCP, UDP and HTTP. The IP stack is considered as the complaint of requirements and 6LoWPAN is included in the low strength edition of OS.

           Additionally, we have highlighted some IoT protocols that are functional in the implementation of Contiki Cooja simulator.

• Very simple control protocol (VSCP)
• OASIS message queuing telemetry transport (MQTT)
• Constrained application protocol (CoAP)
• Advanced message queuing protocol (AMQP)
• Extensible messaging and presence protocol (XMPP)

       For your ease, we have described the sample Contiki code for the implementation of TCP server based communication process.

PROCESS_THREAD(tcp_server_process, ev, data)

{

  PROCESS_BEGIN();

  tcp_socket_register(&socket, NULL,

               inputbuf, sizeof(inputbuf),

               outputbuf, sizeof(outputbuf),

               input, event);

  tcp_socket_listen(&socket, SERVER_PORT);

  printf(“Listening on %d\n”, SERVER_PORT);

  while(1) {

    PROCESS_PAUSE();

    if(bytes_to_send > 0) {

      /* Send header */

      printf(“sending header\n”);

      tcp_socket_send_str(&socket, “HTTP/1.0 200 ok\r\nServer: Contiki tcp-socket example\r\n\r\n”);

      /* Send data */

      printf(“sending data\n”);

      while(bytes_to_send > 0) {

        PROCESS_PAUSE();

        int len, tosend;

        tosend = MIN(bytes_to_send, sizeof(outputbuf));

        len = tcp_socket_send(&socket, (uint8_t *)””, tosend);

        bytes_to_send -= len;

      }

      tcp_socket_close(&socket);

    }

  }

  PROCESS_END();

}
