Why Should I Use Coap When There Is MQTT

Time needed: 6 minutes

Follow from Step 1 to Step 11 in order to create COAP projects. Quick guide to create COAP based Projects. Reach us , if you want an customize COAP projects works for scholars.

1. CoAP

   The Constrained Application Protocol (CoAP) is one of the Internet Application Protocol for constrained device. The CoAP is used for make a process between devices on the same constrained network or, between devices and general nodes on the Internet or between devices on different constrained networks both joined by an internet.

2. Main source file in CoAP

   By this process to use the package of CoAP main source file

3. Source file in COAP server

   By this process to use the installation location in the file

4. Create a simulation

   By the process of getting started to cooja Contiki network simulator to create a simulation

5. Serial Socket server

   By the process of getting started to cooja Contiki network simulator to create a simulation and get the RPL + TSCH to execute the serial socket server

6. MQTT

   The Message Queuing Telemetry Transport (MQTT) is a one of the network protocol that perform the process of transports messages between IoT devices over TCP/IP in the network. The MQTT Publish / Subscribe Architecture , contains the different components , like MQTT Client, like the sensir nodes , subscriber mobile devices and MQTT Broker device.

7. Source code for MQTT

   By the process of getting started mqtt.h(~/contiki/apps/mqtt)-gedit

8. Simulation result

   For get the simulation , execute the command and run , in the terminal

9. Simulation Window

   For get the simulation , execute the command and run , in the terminal go the simulation and get the cooja contiki simulation window successfully.

10. Connect MQTT and COAP

    For make a simulation we promote two protocols ,like MQTT and COAP. The both two Are open standards , and also Are better suited to constrained environments than HTTP. The combination Provide mechanisms for perform the asynchronous communication process and it Run on IP and Have a range of implementations for the simulations. We perform the process by using the following configuration source codes.

11. Configuration of source code in MQTT and COAP

    We perform the process by using the following configuration source codes dc-rpl-coap.csc
