Transmission over wireless fading channels under quality of service (QoS) constraints is studied when only the receiver has channel side information. Being unaware of the channel c...
One of the main issues in the design of sensor networks is energy efficient communication of time-critical data. Energy wastage can be caused by failed packet transmission attempts...
Abstract A key concern in multi-hop wireless networks is energy-efficiency due to batterypower constrained mobile nodes. The network interface is a significant consumer of energy...
