MIMIC MQTT Simulator is a scalable, customizable, programmable, predictable, dynamic simulation platform designed to enable rapid development / testing / deployment / tuning / training / demonstration of large-scale Internet of Things applications.

MIMIC creates a real-world, real-time test lab with thousands of IoT sensors, gateways and devices. It allows suppliers of MQTT sensors, devices, gateways, brokers and applications to design, develop and test their Brokers, Load balancers and clients using secured connections, in a virtual and scalable network environment. MQTT Simulation accelerates evaluation by IoT platform users, and enables them to quickly prototype their proof of concept replacing or supplementing real devices.

MQTT is a "light weight" messaging protocol over TCP/IP for the Internet of Things. It is designed for connections with remote locations where a "small code footprint" is required and/or network bandwidth is limited. The Publish-Subscribe messaging pattern requires a message broker. The broker is responsible for distributing messages to interested subscriber clients based on the topic of a message. With MIMIC MQTT Simulator you can send a variety of custom messages to any MQTT broker that supports ISO standard version 3.1.1 and the new MQTT 5.0 version .

MIMIC MQTT Simulator is specifically designed to mitigate risks associated with deployment of large IoT applications by rapid prototyping of multiple alternatives, and load and feature testing of many scenarios. For rapid integration into your platform of choice, we have published demo tests and tutorial videos with many IoT platforms, such as Amazon AWS IoT Core, Azure IoT Hub, Cumulocity IoT, as well as many on-premise and IoT edge solutions such as Greengrass, PTC Thingworx, Ignition, etc.

By using MIMIC, IoT Application vendors can assure their customers that their applications will be able to handle the scales of connections, topics and varieties of messages to work properly when deployed across heterogeneous environments. They can also create a variety of benchmarks to show the scalability for sensors, volume of messages and topics.

MIMIC MQTT Simulator applies to these areas of publish/subscribe patterns:

  • Industrial IoT
  • IoT Smart City
  • Fleet management
  • Asset tracking
  • Unified Namespace
  • Simulate thousands of Publishers and Subscribers:
    • Each with their own IP address, Port, Client ID and Authentication
    • Each Publisher can publish to multiple, unique topics
    • Each Subscriber can subscribe to multiple, unique topics, including Wildcard topics
    • Each Publisher can be a Subscriber also.
  • Connect to Brokers, MQTT gateways, Load balancers and clients using secured connections using TLS.
  • Authenticate each simulated sensor with OAuth 2.0 server or JSON Web Tokens (JWT)
  • Include Authenticated (with User Name/Password) messages for every connections.
  • Send messages with various QoS levels.
  • Send messages with various message length, different frequencies or malicious information to test the security.
  • MQTT 5 Simulator supports new MQTT 5 features through customizable CONNECT properties, PUBLISH properties
  • Configure Connect and Re-Connect as needed.
  • Simulate faulty sensor network to verify robustness of subscriber application
  • Monitor the round-trip delay (end-to-end MQTT latency) for messages going from Publishers to Subscribers through the Broker.
  • Support layered protocols such as Sparkplug and LWM2M-MQTT

The most common uses of MQTT Simulator are:

  • Development and Testing: MQTT application developers can implement their products quickly and test reliably - specifically, the load testing of scalability against thousands of sensors.
  • Evaluation: By creating various heterogeneous environment of sensors and devices, it is easy to evaluate the suitability of applications with anticipated failure and growth scenarios, or qualify purchases before deployment.
  • Trade Shows: Marketing can setup powerful "live" demonstrations at trade shows.
  • Sales Demos: Sales team can tailor presentations to the individual customer's environment with biggest impact.
  • Training Environments: Realistic training scenarios can explore all possible cases. Training environment can be remote/portable rather than based on the classroom.
Losant with Vehicle Fleet Simulation
10,000 sensors to Eclipse Amlen
  1. MQTT Simulator: MIMIC can simulate 100,000 MQTT 3.1, MQTT 3.1.1 or MQTT 5.0 based sensors and devices. Each one can be started or stopped individually or in a group. Each one has it's own IP address, Port and version. Once started, the device starts sending and responding to the MQTT requests to/from any broker or application from anywhere in the network.
  2. MQTTLAB.IOTSIM.IO: Cloud-based MQTT lab implemented with MIMIC. The portal gives access to entry-level labs for quickly connecting to common IoT platforms and features: AWS IoT, Sparkplug, MQTT5, etc.
  3. MIMICShell: MQTT functionality can be controlled by MIMIC Command line interface.
  4. MIMIC API: MIMIC API in Java, C++, Perl, Python, Tcl, PHP, Javascript to programmatically control the simulations.
  5. MQTT Explorer: MQTT subscriber client to explore MQTT topics in your IoT Platform

Supported Platforms: Windows®, Linux and Amazon Cloud. (details)
