DepSys:Dependency Aware Integration of CPSs for Smart Home

Research Contributions

• Specify, detect and resolve conflicts by requirements, name, and control dependencies

• DepSys automatically resolves control conflicts and allows apps to be run in a more flexible way

• Using 34 days of data and 35 apps(energy, healthy, security and entertainment)

DepSys System Architecture

Spectrum of Dependencies

• Requirement dependency

Requirements of the app: Address the requirement of an app to figure out if the app can be run in the house.
Requirements of the avaiable resources(sensors/actuators): Specified in DepSys and configured by the user/deployer.

• Name dependency
• Control dependency for sensors
• Control dependency fo actuators
• Missing dependency
• App interdependency
