Wireless communication system is expected to provide service with low latency and high energy efficiency. To improve the energy efficiency, the transceiver prefers sending packets, when the channel states are good. However, such opportunistic transmission may induce undesirably large latency. Therefore, a fundamental tradeoff exists between the average transmission power and average queuing delay,...
Communication by wireless portable devices usually has a low energy efficiency and suffers from channel fading. Because of these limitations, assuring Quality of Service(QoS) such as low average transmission delay and packet loss rate under a given energy constraint is becoming an important problem. One efficient solution is considered as cross-layer scheduling which aims to improve the overall performance...
