Secret Key Generation in the Multiterminal Source Model : Communication and Other Aspects
(2018-07-04)
This dissertation is primarily concerned with the communication required to achieve secret key (SK) capacity in a multiterminal source model. The multiterminal source model introduced by Csiszár and Narayan consists of a ...
Robust Nonparametric Sequential Distributed Spectrum Sensing under EMI and Fading
(2018-07-16)
Opportunistic use of unused spectrum could efficiently be carried out using the paradigm
of Cognitive Radio (CR). A spectrum remains idle when the primary user (licensee) is
not using it. The secondary nodes detect this ...
On Codes for Private Information Retrieval and Ceph Implementation of a High-Rate Regenerating Code
(2018-07-09)
Error-control codes, which are being extensively used in communication systems, have found themselves very useful in data storage as well during the past decade. This thesis deals with two types of codes for data storage, ...
On the Tradeoff Of Average Delay, Average Service Cost, and Average Utility for Single Server Queues with Monotone Policies
(2018-04-23)
In this thesis, we study the tradeoff of average delay with average service cost and average utility for both continuous time and discrete time single server queueing models without and with admission control. The continuous ...
Dynamics, Fluctuations and Rheological Applications of Magnetic Nanopropellers
(2018-01-07)
Micron scale robots going inside our body and curing various ailments is a technolog¬ical dream that easily captures our imagination. However, with the advent of novel nanofabrication and nanocharacterization tools there ...
Influence Dynamics on Social Networks
(2018-02-15)
With online social networks such as Facebook and Twitter becoming globally popular, there is renewed interest in understanding the structural and dynamical properties of social networks. In this thesis we study several ...
First-Spike-Latency Codes : Significance, Relation to Neuronal Network Structure and Application to Physiological Recordings
(2018-04-12)
Over the last decade advances in multineuron simultaneous recording techniques have produced huge amounts of data. This has led to the investigation of probable temporal relationships between spike times of neurons as ...
Functional Index Coding, Network Function Computation, and Sum-Product Algorithm for Decoding Network Codes
(2018-01-10)
Network coding was introduced as a means to increase throughput in communication networks when compared to routing. Network coding can be used not only to communicate messages from some nodes in the network to other nodes ...
Analysis of Multi-Conductor Coupled Microstrip Lines with an Aperture in the Ground Plane for Compact Broadband Microwave Components
(2018-04-11)
In recent years, the wireless industry has witnessed tremendous development for the defense and commercial segments. The explosive growth in the modern radio frequency and microwave systems leads to an increased interest ...
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), ...
