In this paper, we investigate the delay and delay-constrained throughput performance of a point-to-point wireless-powered communication system, where one node, e.g. a user equipment (UE), is powered by the wireless energy transferred from the other node, e.g. an access point (AP), and uses the harvested wireless energy to send data to the other node. Our focus is on the delay performance of sending...
Increasingly more devices are using WiFi Direct to establish direct, peer-to-peer connections to each other. By leveraging opportunistic communications through WiFi Direct, mobile social networks (MSNs) enable people with mobile devices to share information without the support of Internet connection. However, the half-duplex nature of WiFi Direct does not allow connected nodes to transmit data simultaneously...
Multi-view video (MVV) consists of multiple video streams captured simultaneously by multiple closely spaced cameras and enables users to freely change their viewpoints by playing different video streams. Those close deployed cameras will capture overlapping frames (OFs) and then transmit OFs in multiple video streams. With the viewpoint change from one stream to another, redundant OFs in the latter...
Carrier Aggregation (CA) has emerged as a promising technique for Long-Term Evolution Advanced (LTE-A) wireless communications to satisfy the ever-increasing bandwidth requirements. However, this technical envisagement puts forward new challenges on radio resource allocation such as serious unbalanced loads among different Component Carriers (CCs). To alleviate this problem, a novel QoS-aware resource...
