Towards Uninterruptible Smart Home Processes
Kai Grunert · 2022
Today's Smart Home protocols specify the functionality and interfaces of Smart Home devices, but they cannot represent arbitrary, complex processes defined by the user. For example, if a speaker has to play music after a motion detector detects movement. This process has to be set up on a centralized automation system. However, if the connection to the Internet breaks down or the involved cloud systems crash, most Smart Home processes will stop working. This paper proposes a decentralized approach where the defined process descriptions are directly transferred to the devices. The devices interpret and execute the process steps themselves with the help of a component called the Distributed Process Engine. This architecture guarantees the reliable execution of Smart Home processes in the event of many possible types of failures.
