IoT Key ElementsDemonstrated on Homie framework

Peter HanzlíkJuly 26, 2016

Configuration API• Way to pass connection details and basic properties of the IoT device,

i.e. not hardcoded into firmware

• Configuration should not define logic of the IoT device

• Provide automated way for configuration deployment=> deploy tens/hundreds/thousands of IoT devices in one shot

Security• IoT Security = An empty buzzword

• IT/OT convergence

• New phenomena: decentralized, P2P protocols, e.g. Blockchain

• IoT = Ecosystem => more surfaces to attack

OTA Updates and Management• Managing version control

• Simplify maintenance complexity

• Challenge: efficient delta updates to minimize resources

Communication Protocol• High Throughput (IoT brings data tsunami)• Real-Time• Low Latency• Bi-Directional

Analytics• IoT is not M2M• Push down: from Cloud to Edge/Node• Edge/Fog Computing• Real-time

• Machine Learning• Distributed analytics• Self-managing systems• Autonomous systems

Intuitive Voice Control• Offline vs Online

• Voice Recognition vs Voice Assistant
