Throughput of a cooperative energy harvesting secondary user in cognitive radio networks
(
Wiley Blackwell
, 2016 , Article)
This paper investigates the maximum throughput of a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU is assumed to be an energy harvesting node, which harvests energy packets from the ...
Energy-Aware Cooperative Wireless Networks with Multiple Cognitive Users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we study and analyze cooperative cognitive radio networks with arbitrary number of secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data ...
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 ...
Utility-based uplink scheduling algorithm for enhancing throughput and fairness in relayed LTE networks
(
IEEE
, 2010 , Conference Paper)
Relaying is one of the key techniques considered by the 3GPP LTE-Advanced as part of 4G cellular technologies, aiming to increase the coverage and capacity of the network especially for the edge nodes. In this work, we ...
Decentralized throughput maximization in cognitive radio wireless mesh networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Scheduling and spectrum allocation are tasks affecting the performance of cognitive radio wireless networks, where heterogeneity in channel availability limits the performance and poses a great challenge on protocol design. ...
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 ...
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 ...
Two way opportunistic MAC protocol for Ad Hoc networks
(
IEEE
, 2011 , Conference Paper)
In this paper, network coding is introduced in relay based MAC protocols for bidirectional traffic to evaluate the performance in terms of throughput and energy. The idea of proposed scheme is to use high data rate nodes ...
On hierarchical network coding versus opportunistic user selection for two-way relay channels with asymmetric data rates
(
IEEE
, 2013 , Article)
We address in this paper the challenge of coping with asymmetric data rates in two-way relay channels. We consider a relay network comprising two sources and one relay. The sources communicate at different rates through ...
