Efficient and Fair Throughput-Optimal Scheduling in Buffer-Aided Relay-Based Cellular Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this letter, we study throughput-optimal scheduling policies in single-path buffer-aided relay networks, where the packets of a user travel one fixed path from the source to the destination and do not require routing. ...
On the effect of proportional fairness in energy transfer for wireless powered communication networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Wireless powered communication network (WPCN) is an emerging area of research where energy is transferred from the access point to the mobile terminals in the downlink and information is transferred in the uplink. In the ...
Optimal spectrum access for a rechargeable cognitive radio user based on energy buffer state
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
Energy-cost-distortion optimization for delay-sensitive M-health applications
(
IEEE Computer Society
, 2015 , Conference Paper)
Mobile-health (m-health) systems leverage wireless and mobile communication technologies to promote new ways to acquire, process, transport, and secure the raw and processed medical data to provide the scalability needed ...
Low complexity target coverage heuristics using mobile cameras
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Wireless sensor and actuator networks have been extensively deployed for enhancing industrial control processes and supply-chains, and many forms of surveillance and environmental monitoring. The availability of low-cost ...
Survey on energy harvesting wireless communications: Challenges and opportunities for radio resource allocation
(
Elsevier B.V.
, 2015 , Article)
Abstract Green radio communications has received a lot of attention in recent years due to its impact on telecom business, technology and environment. On the other hand, energy harvesting communication has emerged as a ...
Power control and group proportional fairness for frequency domain resource allocation in L-SC-FDMA based LTE uplink
(
Kluwer Academic Publishers
, 2015 , Article)
Resource allocation in Long Term Evaluation (LTE) uplink is challenging because of two reasons: (1) it requires contiguous resource block allocation and (2) high complexity due to per user based power allocation among ...
The inapproximability of illuminating polygons by α-floodlights
(
Queen's University, Ontario, Canada
, 2015 , Conference Paper)
We consider variants of the art gallery problem where guard visibility is limited to a certain angular aperture-. We show that the problem is NP-hard even when guards can be located in the interior of the polygon. We then ...
Ambient Intelligence - Software and Applications: 6th International Symposium on Ambient Intelligence (ISAmI 2015)

Channel secondary random process for robust secret key generation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The broadcast nature of wireless communications imposes the risk of information leakage to adversarial users or unauthorized receivers. Therefore, information security between intended users remains a challenging issue. ...
