Distributed Wireless Networks : Link Scheduling And Application Delay Modelling
(2013-05-23)
We address several problems that arise in a multihop wireless mesh network. First, we study the problem of joint congestion control, routing and MAC layer scheduling. We formulate the problem as an aggregate utility ...
Design & Implementation Of Low Power Sigma Delta ADCs For Wide Band Applications
(2013-06-13)
This thesis focuses on the design and implementation of low power Σ∆ ADCs in 130 nanometer CMOS technology. The design issues in the implementation of a third order ADC with a multi-bit and single bit quantizer are discussed. ...
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 ...
A Polymorphic Finite Field Multiplier
(2013-07-03)
Cryptography algorithms like the Advanced Encryption Standard, Elliptic Curve Cryptography algorithms etc are designed using algebraic properties of finite fields. Thus performance of these algorithms depend on performance ...
Design And Analysis Of Microstrip Ring Antennas For Multi-frequency Operations
(2013-06-18)
In this research we attempted several modifications to microstrip ring/loop antennas to design multi-frequency antennas through systematic approaches. Such multi-frequency antennas can be useful while building compact ...
Low Power Receiver Architecture And Algorithms For Low Data Rate Wireless Personal Area Networks
(2013-09-03)
Sensor nodes in a sensor network is power constrained. Transceiver electronics of a node in sensor network consume a good share of total power consumed in the node. The thesis proposes receiver architecture and algorithms ...
Performance Analysis Of Post Detection Integration Techniques In The Presence Of Model Uncertainties
(2013-07-10)
In this thesis, we analyze the performance of the Post Detection Integration (PDI) techniques used for detection of weak DS/CDMA signals in the presence of uncertainty in the frequency, noise variance and data bits. Such ...
Optimum Event Detection In Wireless Sensor Networks
(2013-06-12)
We investigate sequential event detection problems arising in Wireless Sensor Networks (WSNs). A number of battery–powered sensor nodes of the same sensing modality are deployed in a region of interest(ROI). By an event ...
