Joint Congestion Control, Routing And Distributed Link Scheduling In Power Constrained Wireless Mesh Networks
(2010-07-29)
We study the problem of joint congestion control, routing and MAC layer scheduling in multi-hop wireless mesh networks, where the nodes in the network are subjected to energy expenditure rate constraints. As wireless ...
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 ...
A New Digital Receiver For The Ooty Radio Telescope
(2014-10-16)
A new digital receiver was built for the Ooty Radio Telescope (ORT). This new digital receiver system functionally replaces many systems custom-built for various applications at ORT. The thesis presents the receiver design, ...
Performance Modelling Of TCP-Controlled File Transfers In Wireless LANs, And Applications In AP-STA Association
(2013-07-17)
Our work focuses on performance modelling of TCP-controlled file transfers in infrastructure mode IEEE 802.11 wireless networks, and application of the models in developing association schemes. A comprehensive set of ...
Some Applications Of Integer Sequences In Digital Signal Processing And Their Implications On Performance And Architecture
(2013-07-18)
Contemporary research in digital signal processing (DSP) is focused on issues of computational complexity, very high data rate and large quantum of data. Thus, the success in newer applications and areas hinge on handling ...
