Abstract Our earlier embedded QoS-aware residential O li b dd d Q S id ti l gateway (EmQRG) for real-time class-based queuing (CBQ) bandwidth management is i (CBQ) b d idth t i reviewed and experimentally demonstrated. EmQRG’s high QoS is demonstrated in conjunction with a wireless ZigBee network of t temperature/humidity monitoring sensors. t /h idit it i 2011/03/29 2 Toward the Ubiquitously Networked Society
Abstract Critically, the EmQRG sends a top-priority C iti ll th E QRG d t i it over-temperature alarm when any temperature/humidity module reports a t t /h idit d l t temperature exceeding a preset value. This emergency signal has top EmQRG transmission priority. Experiments verify the over-temperature alarm sends/receives “immediately” regardless of heavy network congestion or bottlenecking. 2011/03/29 3 Toward the Ubiquitously Networked Society
