Cooperative Q-learning techniques for distributed online power allocation in femtocell networks
(
John Wiley & Sons, Ltd.
, 2015 , Article)
In this paper, we address the problem of distributed interference management of femtocells that share the same frequency band with macrocells using distributed multi-agent Q-learning. We formulate and solve two problems ...
Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
This paper studies fundamental throughput and delay tradeoffs in cognitive radio systems with cooperative secondary users. We focus on randomized cooperative policies, whereby the secondary user (SU) serves either its own ...
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. ...
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 ...
Buffer-aided relaying improves both throughput and end-to-end delay
(
Springer International Publishing
, 2015 , Article)
Buffer-aided relaying has recently attracted a lot of attention due to the improvement in the system throughput. However, a side effect usually deemed is that buffering at relay nodes results in the increase of packet ...
Utility-based efficient dynamic distributed resource allocation in buffer-aided relay-assisted OFDMA networks
(
Springer International Publishing
, 2015 , Article)
In this paper, we study resource allocation in buffer-aided relay-assisted OFDMA networks. We consider utility-based stochastic optimization framework where there are constraints to be met either instantaneously or in ...
Scalable real-time energy-efficient EEG compression scheme for wireless body area sensor network
(
Elsevier Ltd
, 2015 , Article)
Recent technological advances in wireless body sensor networks have made it possible for the development of innovative medical applications to improve health care and the quality of life. By using miniaturized wireless ...
Fairness scheme for energy efficient H.264/AVC-based video sensor network
(
Springer Berlin Heidelberg
, 2015 , Article)
The availability of advanced wireless sensor nodes enable us to use video processing techniques in a wireless sensor network (WSN) platform. Such paradigm can be used to implement video sensor networks (VSNs) that can serve ...
