Welcome back guys to the conclusion section. And in
this video avoid going to compare cope and
mqtt communication protocol. So guys,
let's get started with that.
So firstly we will talk about message size
versus message over at here. We have four communication
protocols the cope mqtt. Amq
and HTTP the cope and
mqtt has been discussed properly in the course
and HTTP is a generic protocol.
You guys can search on the internet so
Here we will see here. The core messages smaller
as compared to the other and message
overhead is also lower as compared
to the other mqtt comes in the mediocre list
as compared to the
HTTP and amqp but
if we see the HTTP have
a bigger message size capacity, but message overhead
is also higher mean you can
say that message size is directly how
you can say that directly proportional to the message overhead
if your messages increase then message overhead
is also increase
So cope and mqtt is a good to go which minimize
the overhead as compared to the HTTP and
the amqp.
And in the next we are going to compare the
power consumption versus the resource requirements as compared
to the previous slide. Same cope
uses the low power and less
resources as compared to
the other and the mqtt comes in the mediocre list where
it consume a little bit more power as
compared to the core but smaller more resources
as compared to that go but the HTTP
and amqp is on the higher list
which consumes the most more power and the more
resources as compared to the mqtt and the oh
and in the second last we are
going to compare the protocol with the bandwidth versus
the latency the same cope and mqtt have a
lower latency and the lower usage of bandwidth as
compared to the HTTP. It means where we
have a slow internet connection and the
very limited bandwidth just like in a rural
areas where we have a edge or you can say that
GPRS actually many guys would many
guys don't know about these word because now we
are living in the era of 5G and
60 and maybe in the some years
next. We are going to talk about this as seven G
and 80, so I'm talking about the
it's around the 2000.
That I am talking about the edge and the GPR so
that I maybe still there are
many Under 12 countries and many locations where we have the latency
and the bandwidth issues. So the cope and
mqtt works very well on these internet connectivity
and that's why these two communication
Protocols are good for iot notes
because
they didn't consume too much bandwidth and it works
perfectly on the lower latencies.
And finally, we need to talk about the reliability qos
versus the interoperability. So mqtt
is a more reliable
and quality of services are good,
but there's no interoperability with other.
Communication protocols. So cope and
HTTP is compatible interpretable with other Technologies,
but the reliability
is not good as like mqtt. So
here I'm qtt is on
number one, but the disadvantage is
that that it's not interoperable with existing web Technologies
our web protocols.
So guys in the next video, we're going to conclude all
the stuff where I am going to talk about myself.
By which means you can contact with me, so I see
you in the next video. Have a good day, bye-bye.
