The adaptive modulation and coding (AMC) schemes has long been adopted at physical layer to combat time-varying properties of the wireless channel. However, transmitting packet over deep fading channel can render extra energy expenditure, due to the incorporation of more error protection or usage of lower modulation mode, which is unaffordable for energy-limited wireless sensor device. To avoid such...
One of the most important issues in sensor enabled emergency applications is the QoS provisioning. Wireless LANs plays critical role in providing anywhere and anytime connectivity for many sensor enabled emergency applications. This paper addresses the issue of provisioning QoS over the wireless channel between the sensor enabled emergency application and the wireless access points (e.g., wireless...
