On spectrum sharing between energy harvesting cognitive radio users and primary users
(
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 ...
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 ...
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 ...

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 ...
Solar reactor efficiency analysis for alternative fuel production via ferrite based two-step thermochemical splitting of water and CO2
(
AIChE
, 2015 , Conference Paper)
In this paper computational thermodynamic modeling of solar syngas production via ferrite based (Fe3 O4 /FeO) thermochemical H2O and/or CO2 splitting cycle. This two-step cycle involves solar thermal reduction of Fe3O4 ...
Computational thermodynamic analysis of solar fuel production via metal oxide based H2O and CO2 splitting thermochemical cycles
(
AIChE
, 2015 , Conference Paper)
In this paper thermodynamic feasibility of the production of solar fuel via SnO2/SnO based thermochemical CO2 splitting redox reactions was investigated. The first step is the thermal dissociation of SnO2 into SnO where ...
Study of reaction mechanism in solution combustion synthesis of transition metals
(
AIChE
, 2015 , Conference Paper)
In this paper, we investigate the reaction mechanism followed during the solution combustion synthesis of transition metals (Cu, Ni and Co) and their alloys. Metal nitrates were mixed with a choice of fuel (glycine, and ...
