Delay minimization through joint routing and resource allocation in cognitive radio-based mesh networks
(
IEEE
, 2012 , Conference Paper)
We consider wireless mesh networks in which the nodes are utilizing cognitive radios and try to opportunistically gain access to spectrum resources. In such networks, the timely delivery of the traffic is a challenging ...
Optimum power and rate allocation in cluster based video sensor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In a wireless video sensor network (WVSN), each video sensor node consumes a significant amount of power on video compression in addition to the required power for communication. Therefore, the power optimization is a more ...
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 ...
An evolutionary game theoretic approach for cooperative spectrum sensing
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Many spectrum sensing techniques have been proposed to allow a secondary user (SU) to utilize a primary user's (PU) spectrum through opportunistic access. However, few of them have considered the tradeoff between accuracy ...
Interference-based optimal power-efficient access scheme for cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a new optimization-based access strategy of multi-packet reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectrum. We devise an analytical model that ...
On the fairness of frequency domain resource allocation in Wireless Mesh Networks A survey
(
IEEE
, 2011 , Conference Paper)
This article presents a concise survey of fairness-aware frequency domain resource allocation techniques in Wireless Mesh Networks (WMNs). Wireless mesh networks have emerged as a key technology for next generation application ...
Bayesian network based heuristic for energy aware EEG signal classification
(
SpringerLink
, 2013 , Conference Paper)
A major challenge in the current research of wireless electroencephalograph (EEG) sensor-based medical or Brain Computer Interface applications is how to classify EEG signals as accurately and energy efficient as possible. ...
Joint routing and resource allocation for delay sensitive traffic in cognitive mesh networks
(
IEEE
, 2011 , Conference Paper)
In this paper we study the problem of joint design of routing and resource allocation in cognitive radio based wireless mesh networks. Our study focuses on a cognitive system model in which secondary nodes have delay ...
QUMESH: Wireless mesh network deployment and configuration in harsh environment
(
IEEE
, 2012 , Conference Paper)
The link delivery probability in a wireless mesh network is most accurately determined only by experiment, as it depends on many factors, including environment characteristics, transmission power, distance between transmitter ...
