Mobile devices like smartphones and tablet computers became an integral part of our modern world and single-board computers like Raspberry Pi are cheaper today than at any time before. Simple and open Machine-to-Machine (M2M) protocols like MQTT enable these devices to communicate in an efficient manner, even in scenarios with unreliable and instable networks. This talk shows how different Java MQTT libraries can be utilized for professional and personal projects to build efficient and scalable solutions for (mobile) devices. You will also see how modern technologies like WebSocket can be used in conjunction with MQTT to build real time-push services to bring data from sensor hardware to browsers in a scalable manner.
