Abstract
Occupancy detection in smart buildings suffers from high sensor unreliability. The combination of data from multiple sensors can largely improve reliability. However, battery-powered sensor nodes have communication limitations. This paper addresses the problem of presence detection in a building as Distributed Sensing of a Hidden Markov Model (DS-HMM). Optimal solutions require excessive communication over a perfectly reliable channel. We propose and investigate an efficient transmission policy, jointly with a fusion algorithm, to merge data from various HMMs running separately on all sensor nodes. The algorithm showed improved performance and potential energy savings in a real world set-up, where user presence and sensor errors may not exactly follow idealized model assumptions.
