Timer-Based Selection Schemes for Wireless Networks
(2018-04-05)
Opportunistic selection is a practically appealing technique that is often used in multi-node wireless systems such as scheduling and rate adaptation in cellular systems and opportunistic wireless local area networks, ...
On Network Coding and Network-Error Correction
(2018-04-24)
The paradigm of network coding was introduced as a means to conserve bandwidth (or equivalently increase throughput) in information flow networks. Network coding makes use of the fact that unlike physical commodities, ...
Spectrum Sensing in Cognitive Radios using Distributed Sequential Detection
(2018-03-17)
Cognitive Radios are emerging communication systems which efficiently utilize the unused licensed radio spectrum called spectral holes. They run Spectrum sensing algorithms to identify these spectral holes. These holes ...
Towards a Unified Framework for Design of MEMS based VLSI Systems
(2018-02-12)
Current day VLSI systems have started seeing increasing percentages of multiple energy domain components being integrated into the mainstream. Energy domains such as mechanical, optical, fluidic etc. have become all pervasive ...
SOI Based Integrated-Optic Microring Resonators for Biomedical Sensing Applications
(2018-02-23)
Integrated Silicon Photonics has emerged as a powerful platform in the last
two decades amongst high-bandwidth technologies, particularly since the adop-
tion of CMOS compatible silicon-on-insulator(SOI) substrates. Microring ...
Wide-Band Radio-Frequency All-Pass Networks for Analog Signal Processing
(2018-01-10)
There is an ever increasing demand for higher spectral usage in wireless communication, radar and imaging systems. Higher spectral efficiency can be achieved using components that are aware of system environment and adapt ...
Topics in Network Utility Maximization : Interior Point and Finite-step Methods
(2018-03-12)
Network utility maximization has emerged as a powerful tool in studying flow control, resource allocation and other cross-layer optimization problems. In this work, we study a flow control problem in the optimization ...
Computational Models of Perceptual Space : From Simple Features to Complex Shapes
(2018-02-15)
Dissimilarity plays a very important role in object recognition. But, finding perceptual dissimilarity between objects is non-trivial as it is not equivalent to the pixel dissimilarity between the objects (For example, two ...
Modelling and Performance Analysis of New Coolstreaming for P2P IPTV
(2018-02-23)
Peer to peer networks are becoming increasingly popular among Internet users as the downloading peers share the storage and upload bandwidth load of the system. This makes it possible for a large number of users to share ...
Analysis and Optimization of Cooperative Amplify-and-Forward Relaying with Imperfect Channel Estimates
(2018-03-17)
Relay-based cooperation promises significant gains in a wireless network as it provides an inde-pendent path between a source and a destination. Using simple single antenna nodes, it exploits the spatial diversity provided ...
