Introduction
The SMQ Architecture is an Internet of Things (IoT) publish subscribe end-to-end solution that is optimized for embedded systems to provide instantaneous Device Edge Node connectivity, 1 to 1 Communications, and Ease of Transcending Firewalls. The solution is ideal for resource constrained devices that require real-time dynamic control, analytic information, and firmware updates in both LAN and WAN environments.
Architecture Component List
- SMQ C Client (Non-secure)
- SharkMQ (Secure) C Client
- SMQjs (Javascript)
- SMQ JAVA
- SMQ Broker
SMQ Client-example
A (non-secure) C Client implementation of the SMQ protocol demonstrating device control over the on board LEDs via any modern (WebSocket enabled) Browser interface.

How to setup your own SMQ IoT cloud server
Most IoT cloud server solutions, whether they provide ready-to-use hosted services or not, are based on a standard Virtual Private Server (VPS). Most developers probably think of Amazon or Microsoft Azure's services when considering the server side of their IoT solution. These high-end services are great if you need to scale up to millions of connected devices. However, for most small-scale operations and DIY projects, a low-cost VPS is more than adequate.
