摘要: We investigate QoS provisioning in a Wireless Activity Monitoring Network(WAMN) when data traffic is mixture of emergency short voice commands and 3D accelerometer signals for remote monitoring group elderly people living health care building. Nodes equipped with acoustic sensors form multi hop wireless sensor network. The network carries class to the sink over service differentiation protocol processing. Utilization limited resources critical feasible quality service. analyze performance trade-offs elaborate on optimal buffer length, MAC retransmission count transmit power best achievable at sink. Based results extensive simulations, we conclude some remarks tuning off segment reliability terms novel R-factor metric given scenario.
