Since video services are expected to constitute a major portion of the mobile downlink traffic, it is important to consider end users' perceptual quality of experience (QoE) for video traffic in the system design and performance evaluation of next generation mobile networks. We present a novel QoE-aware scheduling scheme for buffered video on demand (VoD). Therein, rebuffering is the critical attribute...
The provision of very high data rates in a ubiquitous manner throughout the service area is a great challenge for 4G and beyond-4G wireless networks. Towards that end, the deployment of fixed relays by the operators has become an accepted radio access network concept in various standardization activities including LTE-A and 802.16j. It is envisaged that next-generation networks will comprise a plethora...
Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted technologies for emerging wireless communications standards. The activities in many wireless standardization bodies and forums, for example IEEE 802.16 j/m and LTE-Advanced, attest to this fact. The availability or lack thereof of efficient radio resource management (RRM) could make or mar the opportunities in these...
