IOT
The Internet of Things connects physical objects through sensors, connectivity, and processes which allows them to interact digitally. RFID tags and other sensors embedded in physical objects give them the ability to be monitored and controlled remotely via the Internet without constant human monitoring of data. Challenges include ensuring variety of connectivity standards, securely sensing environments, managing power consumption, protecting privacy and security, developing applications for non-experts, and utilizing cloud services. Potential applications include smart lighting, smart roads, earthquake detection, Google Glass, and saving energy in smart homes.
