How to attach the variable in data packet RPL contiki cooja?

To attach the additional variable in RPL data packet using contiki cooja simulator.

Description

To attach the additional variable in RPL data packet using contiki cooja simulator.

  • Step 1: open a file at location: contiki/examples/ipv6/rpl-udp/
    udp-client.c file sends the data packets in the function

    static void send_packet(void *ptr) {
    uip_udp_packet_sendto(client_conn,data_buf,strlen(data_buf),&server_ipaddr, UIP_HTONS(UDP_SERVER_PORT));
    }
    strcat(data_buf,buf);
    strcat(data_buf,bb);
    strcat(data_buf,privalue);
    strcat(data_buf,bb);

  • Step 2: Run the simulation

  • Step 3: Client side: Attach the variable in data packet
