IoT technology:• processor with low power consumption (Intel Edison)• communication: Bluetooth (4.2, smart), Wi-Fi (Direct,
802.11ah, 802.11p), NFC, 4G• Clouds and BIG data• Web interface (HTML5, JavaScript, CSS)• MQTT protocol (Message Queue Telemetry Transport)• CoAP (Constrained Application Protocol)• IETF protocol (Internet Engineering Task Force)• SCADA (Supervisory control and data acquisition)
Companies and Projects:
IBM & ARM (mBed IoT Starter Kit), Samsung (Smart Things), Apple (Home Kit/CloudKit/HelthKit), Google (Nest Labs – Nest/Chromecast), Tibbo (Aggre Gate), Gemalto & Oracle (Cinterion Concept Broad), Intel (processor Edison, modem XMM 6255), else (Spotty, Psi Kick, Thing Worx Marketplace, Xively), etc.
Why Java?• “Write once, run anywhere”!• Run on wide range of devices (from mobile and
embedded system with limited CPU and memory, to servers with immense power and capacity)
• JVM (safety & secure)• work with BIG data & clouds• 9 million developers• 3 billion devices• 125 multimedia devices• 10 billion Java Cards
