HTTP, WS & MQTT for IoT

A brief description about some of the widely used web protocols like HTTP, Websocket and MQTT and how it works in the area of IoT.

Very informative. I greatly enhanced my knowledge of IoT by just watching this lecture and hope to see rest of the series. Where to use HTTP(s), Websocket and MQTT is something I learnt today.

Amazing explanation, really glad having found this video. Everything is much much more clearer now!!
Thanks a lot man!

Clearly explained on the difference between http, ws and mqtt protocol. It would be helpful if more information shared on mqtt protocol. Thanks.

Thank you. HTTP and WS were well explained. It would have been better if you have explaine how MQTT helps to have a better battery life and its low bandwidth consumption. Appreciate your effort.

Great explanation, thnx for sharing! 👍🏼

Excellent vid and explanations.. thanks!

It would be cool, if you can make a example for each protocol using Arduino & Sim900. And than compare the used bandwith.

Great explanation on MQTT with practical examples of actual implementation scenarios. I would like to see the extension of the same scenerio with actual code, like the API calls on the Publisher end and the subscriber ends, if possible..then the implementation concept will be very clear to anyone who wants to create workable solutions to publish data from an MQTT Publisher and subscribe and receive the same (published data) by the client..actual code.. is it written in script form?

how is ws not blocked by firewalls? I mean if there any firewall that will close connection over its port, it is then blocked.
using TCP is all about security.

How MQTT work in the UPI when we pay online to any platform like phonepay & paytam etc

11:55 you said that mqtt is over tcp/ip. actually did you mean under tcp/ip? because i understandtd that from top to bottom, htpp to tcp/ip it covers one by one and i understand that http is more wider area and tcp/is less wide and the mqtt is the least wide in these perspective. i mean mqtt should work under tcp/ip should not over?

Hi, please can i have this presentation please
