MIMIC MQTT Simulator interoperates with major brokers

In addition to our prior published reports, we recently simulated
thousands of sensors to 3 more brokers




with thousands of arbitrary messages per second published.

Regardless which broker you select, you can perform prototyping, scalability,
robustness and security testing of your IoT application with
MIMIC MQTT Simulator prior to deployment.

How is realistic MQTT testing with MIMIC different from simplistic testing?

Most simple test apps use a for loop to create connections to a MQTT broker,
using only one single IP address for a large number of client sessions.

By using one IP address per session with MIMIC MQTT Simulator just like in

real world scenarios (when do real sensors share IP addresses?) we
uncovered a flaw in third-party MQTT brokers (at least 2 that we have

They would fail after a small number of simulated sensors (typically 1000

Only after adjusting the ARP cache parameters on the broker systems did
we overcome this problem.

MIMIC allows you to create realistic IoT pre-deployment testing scenarios
using IPv4 or IPv6 addressing, just like in the real world.

MIMIC MQTT Simulator publishing synthetic load to HiveMQ

MIMIC MQTT Simulator is simulating 40,000 connected sensors.
The HiveMQ MQTT Broker connected with them as if they are physical
sensors. As shown in the graphs, MIMIC is generating messages at the
rate of around 4,000 messages / second.

In this scenario it has been running for many hours.
The 40001st connection is a third-party subscriber client. This shows
that MIMIC simulated sensors are no different than the real one.

MIMIC allows you to stage precise pre-deployment tests for HiveMQ and
other IoT applications to make sure they handle the expected load and
provide the needed performance. In addition, you can easily customize
message payloads of simulated sensors for rapid prototyping, and create
pathological scenarios to minimize risks.

MIMIC MQTT Simulator for rapid prototyping of Amazon AWS IoT applications

A simulated sensor in MIMIC MQTT Simulator is generating JSON
messages to Amazon AWS IoT . The AWS subscriber client is showing
the received messages.

MIMIC allows rapid prototyping of many publishers with custom payloads
and custom message rates. By simulating thousands of such sensors you
can benchmark your performance with AWS IoT

Setting up a benchmarking environment to test the performance
of large-scale IoT applications is specially cumbersome. It needs a large
number of sensors, each with different IP address. Each type of sensor
sends out different messages at different rates and with unique content.

MIMIC MQTT Simulator creates such an environment with thousands of
sensors. In this example we have simulated an Intel sensor that sends
messages to the AWS IoT gateway. You can see in the image that the
messages are received by the AWS IoT subscriber client. The MIMIC log
window shows the connection-related transactions.

This can be easily multiplied to simulate thousands of sensors to create an
IoT lab with the desired variety of sensors. You can use the environment to
benchmark the performance matrix for your IoT applications.

Benchmark your MQTT application with MIMIC MQTT Simulator

Now you too can benchmark your MQTT application with MIMIC MQTT Simulator.

Here the IBM MessageSight MQTT broker is handling 100,000 connections
from MIMIC simulated MQTT sensors publishing messages at around 10,000
/ second to one subscriber client.

Everything in the MIMIC MQTT Simulator is runtime-configurable to suit
your custom requirements.

MIMIC MQTT Simulator interoperates with IBM MessageSight

In a little over 10 minutes we start 20,000 simulated sensors connecting
to the IBM MessageSight MQTT Broker. Each sensor on its own IP address
is publishing messages at the rate of 1 / minute to its own topic, for
a total of around 340 / second. Since the broker is forwarding those to
the lone subscriber, the overall message rate is doubled as shown.

With MIMIC MQTT Simulator you can simulate up to 100,000 (yes, one
hundred thousand) sensors from one host.

MIMIC Simulator simulates Internet of Things

The number of Internet of Things devices by 2020 is forecast between
20+ BILLION devices according to Gartner and 38 BILLION according to
Juniper Research.

MIMIC MQTT Simulator supports simulating up to 100k (yes, 100000)
sensors from one host. You can generate any message for any sensor type
with any frequency to test your brokers and subscribers. Any number of
hosts can be controlled to provide unlimited scalability.
