The number of wireless access points (APs) have increased rapidly in recent years to support increasing demands of wireless local area network. However, some of the research findings show that many of these APs are actually idle mainly during off-peak hours, i.e., there is no active user to support within their coverage areas during that time. Nevertheless,… (More)
Under the concept of Web-of-Object (WoO), emergency service is one of the key components in smart home care. Most distinctive characteristics of the emergency service are prompt detection, confidential decision making, and immediate reaction. For that, besides the general service management, the sensor data management, context processing, and communication… (More)
