“…The early stage investigations on smart home mainly focus on context acquisition and distribution with the novel sensing techniques and wireless network solutions for proof of concept development, such as indoor environment monitoring [9], wireless smart home sensor network [10], WSN topology control for network coverage and connectivity [11], WSAN for production automation [12], interoperable device usage [13,14], graphic user interface for remote control [15], network protocols and standards [16], trust and security [17], and service oriented smart home architecture [18]. With the advance of relevant techniques, more and more research work transfers to high-level smart home applications and the models and methods considering how to facilitate occupants' daily lives, such as RADL (Recognizing Activities of Daily Living) [19], elderly care [20], medical care [21,22], realtime energy consumption load forecasting [23], and sustainable homes [7].…”
