Energy Harvesting Wireless Sensor Networks : Performance Evaluation And Trade-offs
(2017-09-23)
Wireless sensor networks(WSNs) have a diverse set of applications such as military surveillance, health and environmental monitoring, and home automation. Sensor nodes are equipped with pre-charged batteries, which drain ...
Distributed Algorithms for Power Allocation Games on Gaussian Interference Channels
(2017-09-20)
We consider a wireless communication system in which there are N transmitter-receiver pairs and each transmitter wants to communicate with its corresponding receiver. This is modelled as an interference channel. We propose ...
Fundamentals Limits Of Communication In Interference Limited Environments
(2017-08-21)
In multiuser wireless communications, interference not only limits the performance of the system, but also allows users to eavesdrop on other users’ messages. Hence, interference management in multiuser wireless communication ...
Finding A Subset Of Non-defective Items From A Large Population : Fundamental Limits And Efficient Algorithms
(2017-07-12)
Consider a large population containing a small number of defective items. A commonly
encountered goal is to identify the defective items, for example, to isolate them. In the classical non-adaptive group testing (NAGT) ...
Delay Differentiation By Balancing Weighted Queue Lengths
(2017-05-04)
Scheduling policies adopted for statistical multiplexing should provide delay differentiation between different traffic classes, where each class represents an aggregate traffic of individual applications having same ...
Low Power And Low Spur Frequency Synthesizer Circuit Techniques For Energy Efficient Wireless Transmitters
(2017-09-07)
There has been a huge rise in interest in the design of energy efficient wireless sensor networks (WSN) and body area networks (BAN) with the advent of many new applications over the last few decades. The number of sensor ...
Optimal Amplify-And-Forward Relaying For Cooperative Communications And Underlay Cognitive Radio
(2017-08-21)
Relay-assisted cooperative communication exploits spatial diversity to combat wireless fading, and is an appealing technology for next generation wireless systems. Several relay cooperation protocols have been proposed in ...
On The Best-m Feedback Scheme In OFDM Systems With Correlated Subchannels
(2017-07-07)
Orthogonal frequency division multiplexing (OFDM) in next generation wireless systems provides high downlink data rates by employing frequency-domain scheduling and rate adaptation at the base station (BS). However, in ...
Resource Management In Celluar And Mobile Opportunistic Networks
(2015-01-07)
In this thesis we study several resource management problems in two classes of wireless networks. The thesis is in two parts, the first being concerned with game theoretic approaches for cellular networks, and the second ...
