Secure data delivery in mobile ad hoc network using multiple paths
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
A mobile ad hoc network (MANET) is a self configurable, self organized, infrastructure less multi hop mobile wireless network.Characteristics of ad hoc network make security a critical issue i.e. any node can join the ...
Development of difference detection algorithm for surveillance video compression
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Video surveillance is widely used tool in today’s era for improving public and residential safety. Here the size of the video data is much higher due to large number of surveillance cameras scattered over large area and ...
Low-power multi-ported register file for digital signal processors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Digital Signal Processors (DSPs) also come under the category of processors in which Multi-ported register files can find their applications widely. Most of the DSP applications do not benefit from further speeding-up after ...
Speaker recognition over VoIP network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
This thesis deals with the Automatic Speaker Recognition (ASR) system over narrowband Voice over Internet Protocol (VoIP) networks. There are several artifacts of VoIP network such as speech codec, packet loss and packet ...
Design of metamaterial
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Meta materials are artificially designed materials that exhibit very high transmission values within a frequency range. Double Negative (DNG) Meta material shows both negative permittivity and negative permeability within ...
Optical wireless sensor network design for a conducting chamber
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Now a day’s majority of the wireless sensor networks (WSNs) are based on Radio Frequency (RF) communication technology. But RF when used in an environment like that of metallic, conducting chamber exhibits large amount of ...
Acyclic edge coloring of complete r-partite graphs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
An acyclic edge coloring of a graph G is a proper edge coloring of G which has no dichromatic cycle. The minimum number of colors required to acyclically edge color graph G is called its acyclic chromatic index, denoted ...
Asynchronous analog to digital converter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Nowadays, asynchronous systems are becoming more popular for low power applications. Asynchronous Systems help to reduce metastability errors and clock skew errors. This thesis is about an asynchronous analog to digital ...
Plagiarism detection
