Exploring blind online scheduling for mobile cloud multimedia services
(2013 , Article)
Mobile cloud is a new emerging technology which can be used to enable users to enjoy abundant multimedia applications in a pervasive computing environment. Therefore, the scheduling of massive multimedia flows with ...
Secure Data Discovery and Dissemination based on Hash Tree for Wireless Sensor Networks
(2013 , Article)
Wireless sensor networks (WSNs) are widely applicable in monitoring and control of environment parameters. It is sometimes necessary to disseminate data through wireless links after they are deployed in order to adjust ...
Improving macrocell downlink throughput in rayleigh fading channel environment through femtocell user cooperation
(2013 , Article)
This paper studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically derive and evaluate the achievable performance of these ...
Securing vehicle-to-grid communications in the smart grid
(2013 , Article)
Using vehicle-to-grid (V2G) services, battery vehicles (BVs) may help the smart grid alleviate peaks in power consumption. However, wireless communications infrastructure between BVs and the smart grid also introduce severe ...
Impact of channel estimation error on bidirectional MABC-AF relaying with asymmetric traffic requirements
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
Channel estimation error results in severe performance deterioration in wireless networks. In this paper, we study the impact of imperfect channel estimation (ICE) on the outage performance of bidirectional relaying where ...
Carrier aggregation for LTE-advanced: Uplink multiple access and transmission enhancement features
(2013 , Article)
Multiple access and transmission enhancement in support of carrier aggregation techniques has been actively studied in the 3GPP LTEAdvanced standardization process of the nextgeneration mobile broadband communication ...
A measurement study on the topologies of BitTorrent networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
BitTorrent (BT) is a widely-used peer-to-peer (P2P) application. Most of BT's characteristics (except the topology) have been studied extensively by measurement approaches. In this paper, we deploy a measurement system to ...
Capacity and delay analysis for data gathering with compressive sensing in wireless sensor networks
(2013 , Article)
Compressive sensing (CS) provides a new paradigm for efficient data gathering in wireless sensor networks (WSNs). In this paper, with the assumption that sensor data is sparse we apply the theory of CS to data gathering ...
Resource allocation with incomplete information for QoE-driven multimedia communications
(2013 , Article)
Most existing Quality of Experience (QoE)-driven multimedia resource allocation methods assume that the QoE model of each user is known to the controller before the start of the multimedia playout. However, this assumption ...
A weighted real-time predictive controller for a grid connected flying capacitors inverter
(
Elsevier
, 2013 , Article)
This paper proposes a new controller for a grid connected power conditioning unit (PCU). The PCU consists of a flying capacitors inverter (FCI) connected to the grid through an inductor and a step-up transformer. A hybrid ...
