Resource Allocation in Wireless Networks for Secure Transmission and Utility Maximization
(2018-02-16)
Resource allocation in wireless networks is one of the most studied class of problems. Generally, these problems are formulated as utility maximization problems under relevant constraints. The challenges posed by these ...
Wireless Sensor Networks : Bit Transport Maximization and Delay Efficient Function Computation
(2018-04-02)
We consider a wireless sensor network, in which end users are interested in maximizing the useful information supplied by the network till network partition due to inevitable node deaths. Neither throughput maximization ...
Wireless and Social Networks : Some Challenges and Insights
(2018-02-07)
Wireless networks have potential applications in wireless Internet connectivity, battlefields, disaster relief, and cyber-physical systems. While the nodes in these networks communicate with each other over the air, the ...
Spatially Correlated Data Accuracy Estimation Models in Wireless Sensor Networks
(2018-02-10)
One of the major applications of wireless sensor networks is to sense accurate and reliable data from the physical environment with or without a priori knowledge of data statistics. To extract accurate data from the physical ...
Content Distribution in Social Groups
(2018-01-29)
We study Social Groups consisting of self-interested inter-connected nodes looking for common content. We can observe Social Groups in various socio-technological networks, such as Cellular Network assisted Device-to-Device ...
Architecture and Design of Wide Band Spectrum Sensing Receiver for Cognitive Radio Systems
(2018-01-03)
To explore spectral opportunities in wideband regime for cognitive radio we need a wideband spectrum sensing receiver. Current wideband receiver architectures need wideband analog to digital converter (ADC) to sample ...
Precoding for Interference Management in Wireless and Wireline Networks
(2018-02-27)
Multiple users compete for a common resource like bandwidth to communicate
data in interference networks. Existing approaches in dealing with interference
limit the rate of communication due to paucity of shared resources. ...
Design and Development of a Passive Infra-Red-Based Sensor Platform for Outdoor Deployment
(2018-04-23)
This thesis presents the development of a Sensor Tower Platform (STP) comprised of an array of Passive Infra-Red (PIR) sensors along with a classification algorithm that enables the STP to distinguish between human intrusion, ...
Multi-Antenna Communication Receivers Using Metaheuristics and Machine Learning Algorithms
(2018-04-23)
In this thesis, our focus is on low-complexity, high-performance detection algorithms for multi-antenna communication receivers. A key contribution in this thesis is the demonstration that efficient algorithms from ...
Fast, Scalable, Contention-Based Algorithms for Multi-Node Selection in OFDMA and Cooperative Wireless Systems
(2018-04-23)
Opportunistic selection algorithms have grown in importance as next generation wireless systems strive towards higher data rates and spectral efficiencies. For example, in orthogonal frequency division multiple access(OFDMA), ...
