Mobility aware MANET routing protocol using cross layer design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Mobile Adhoc Network (MANET) is a dynamic network with time varying topology and time varying network resources. Due to the error-prone wireless channel and high mobility, traditional protocols of wired networks cannot be ...
Practical approaches for photometric stereo
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
In this thesis work, we aim to propose approaches for photometric stereo that are less time consuming and have low computational requirements. Many applications of computer vision require high resolution 3-D structure of ...
Hot and cold data identification using query aware hybrid partitioning
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
The price of main memory is reducing with time, which helps to store huge amount of data in the memory. OLTP applications have large database size. It is observed that some applications exhibit skewed access pattern i.e. ...
Formal semantic simplification of Wh-query in english
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)
The problem of Natural Language Query Formalization is to understand the semantics of a user given query in natural language (NL) and then translating the Query into a formal language (FL) such that the FL semantic ...
Modeling MANETs using queuing networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Mobile Ad Hoc Networks (MANETs) are becoming an attractive solution to the services that require flexible establishment, dynamic and low cost wireless connectivity. Since nodes are mobile, routing results vary significantly ...
Statistical delay modeling and analysis for system on chip
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
It is seen that designing using conventional methodologies in Deep Sub Micron geometries, at times, ends up in very pessimistic design and less yield. This is because, today’s tools don’t consider statistical variation of ...
Lifetime analysis of wireless sensor nodes using queuing models
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Prolonging the lifetime of wireless sensor networks (WSN) is one of the key issues for wireless sensor network applications. For increasing the lifetime of network, each node should conserve its energy. Sensor nodes consume ...
Channel estimation in OFDM systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Orthogonal frequency division multiplexing (OFDM) is not a new concept, but its receiver design has constant improvement. OFDM uses available spectrum efficiently and the system provides high data rates. Many standards ...
Study of MPLS traffic engineering with constraint-based routing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Multi-protocol Label Switching (MPLS) is fast becoming popular for future communication networks running applications demanding high speed and Quality of Service. In this work, we have studied the evolution of MPLS, various ...
Design of low-voltage, low-power, wide-band CMOS LC VCO using active inductors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In this thesis the design of low-voltage, low-power, wide-band CMOS LC VCO using active inductor has been proposed. The oscillator is based upon the classic LC-tuned negative-resistance topology, with a novel active inductor ...
