Rivulet is a fault-tolerant distributed platform for running smart-home applications; it can tolerate failures typical for a home environment (e.g., link losses, network partitions, sensor failures, and device crashes). In contrast to existing cloud-centric solutions, which rely exclusively on a home gateway device, Rivulet leverages redundant smart consumer appliances (e.g., TVs, Refrigerators) to spread sensing and actuation across devices local to the home, and avoids making the Smart-Home Hub a single point of failure. Rivulet ensures event delivery in the presence of link loss, network partitions and other failures in the home, to enable applications with reliable sensing in the case of sensor failures, and event processing in the presence of device crashes. In this paper, we present the design and implementation of Rivulet, and evaluate its effective handling of failures in a smart home.
