Google calls time on ambitious Android-in-everything project

Excerpt:

Google has put an official expiry date on an ambitious internet of things (IoT) project that failed to catch light: Android Things. In an announcement, the company warned developers wouldn’t be able to create new projects from the platform as of January 2021.

Launched in developer preview in 2016, Android Things is an embedded operating system designed to run low-power IoT devices with as little as 32 MB of memory. The operating system used a protocol called Weave, which Google announced simultaneously with Android Things, to communicate with other devices over Bluetooth Low Energy and Wi-Fi.

Air Force researchers have invented a wireless, non-intrusive system for authenticating Internet of Things (IoT) network devices, such as fitness trackers and smartwatches.

Excerpt:

IoT networks pose threats to the security and privacy of exchanged information. For example, different types of data breaches, such as information leakage and false data injection, may be initiated in one network device when connecting to another device. Implementing existing security techniques in IoT architectures may not be feasible because devices such as fitness trackers and smartwatches have less battery and processing power than computers or smartphones.
