QoE Power-Efficient Multimedia Delivery Method for LTE-A

Energy Efficient Multimedia Delivery Services over LTE/LTE-A

Mobile video services are becoming a dominant traffic category in emerging fourth generation (4G) cellular networks such as the 3GPP Long-Term Evolution (LTE) and LTE-Advanced (LTE-A). In particular, mobile video unicasting services based on 3GPP Dynamic Adaptive Streaming over HTTP (DASH) and multicasting/broadcasting services based on 3GPP evolved Multimedia Multicast/Broadcast Service (eMBMS...

QoE-driven LTE Downlink Scheduling for Multimedia Services

A Power Efficient Transmission Method for Wireless Multimedia Sensor Networks

The data size of multimedia information is much larger than that of sensor networks. It is required to use efficient protocols on WMSNs to reduce power consumption for multimedia data transmission. The overhearing method is used to transfer multimedia data to reduce transmission overhead to transmit next packets during the unused time interval. The proposed method has been verified its performa...

Cross-layer QoE-driven admission control and resource allocation for adaptive multimedia services in LTE

This paper proposes novel resource management mechanisms for multimedia services in 3GPP Long Term Evolution (LTE) networks aimed at enhancing session establishment success and network resources management, while maintaining acceptable end-user quality of experience (QoE) levels. We focus on two aspects, namely admission control mechanisms and resource allocation. Our cross-layer approach relie...

A computationally efficient method for self-planning uplink power control parameters in LTE

Uplink power control has a strong impact on the performance of mobile communication networks. In this work, an automatic parameter planning algorithm for the standardized power control scheme in the physical uplink shared channel (PUSCH) of long term evolution LTE is proposed. The method is conceived for the network design stage, when network measurements are still not available. The proposed h...
