The proliferation of connected sensing devices (or Internet of Things) can in theory enable a range of applications that make rich inferences about users and their environment. But in practice developing such applications today is arduous because they must implement all data sensing and inference logic, even as devices move or are temporarily disconnected. We develop Beam, a framework that simplifies IoT applications by letting them specify \u201cwhat should be sensed or inferred,\u201d without worrying about \u201chow it is sensed or inferred.\u201d Beam introduces the key abstraction of an inference graph to decouple applications from the mechanics of sensing and drawing inferences. The inference graph allows Beam to address three important challenges: (1) device selection in heterogeneous environments, (2) efficient resource usage, and (3) handling device disconnections. Using Beam we develop two diverse applications that use several different types of devices and show that their implementations required up to 12\u00d7 fewer source lines of code while resulting in up to 3\u00d7 higher inference accuracy<\/p>\n","protected":false},"excerpt":{"rendered":"
