OpenIoT & ELC 2016

The Linux OS has been steadily displacing Real-Time Operating Systems on embedded devices for the past decade. Now Linux has become the de-facto OS of intelligent “edge” devices in the Internet of Things. The combination of low cost, reliability and availability of software and drivers makes Linux a smart choice for IoT startups and established vendors alike. The Java language further reduces time to market and increases reliability and the OSGi framework adds software components and over-the-network updates. A Linux+Java+OSGi software stack is a compelling solution for many IoT products, but it faces some challenges. An important issue is response to time-critical events. This talk will discuss how an embedded real-time Java VM can achieve sub-millisecond response times on Linux for IoT gateways and edge devices.
