Classification of quantum cryptography
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Modern Classical Cryptography is divided into two parts. The first part is Asymmetric (public-key) cryptography and the second is Symmetric (private or secret-key) cryptography. In spite of its popularity public-key ...
Automated categorization of structured documents
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Automatic text categorization is a problem of assigning text documents to pre¬-defined categories. This requires extraction of useful features. In most of the applications, text document features are commonly represented ...
Design and analysis of energy aware protocol-MPEARLE
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Due to the technological advances and development in the field of micro electronic devices, the availability of compact, high-performance, customizable, intelligent devices at low cost has become reality. 'Wireless Sensor ...
Design and implementation of network intrusion detection system
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Most of the intrusion detection systems are based on matching signatures or rules. These rules are the patterns that define the possibility of occurrence of attack. Such signature based intrusion detection system look at ...
Design of CMOS front end for 900MHz RF receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Portable wireless personal communication systems such as cellular phones, message pagers, and wireless modems traditionally have been built from a mixture of IC technologies. In fact if we section a commercial cellular ...
Design of AHB-Wishbone bridge
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
System-on-Chip (SoC) design is performed through integration of pre-designed components, called intellectual Property (IP). Design reuse is a critical feature in SoC design. Design reuse is the simple concept of using IP ...
Fractal based approach for face recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
An automated face recognition system is proposed in this dissertation. The system efficiently recognizes a candidate (test) image using the interdependence of the pixel that arises from the fractal compression of the image. ...
Integrated receiver front-end: system level architectures and design issues for CDMA based applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
During the last decade, the world of mobile communications has experienced an enormous growth. Among the important factors has been possible by the migration from the original analog mobile phones to handsets using digital ...
Incorporation of mobility model of nodes in zone routing protocol for mobile ad hoc wireless networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Ad Hoc wireless networks are characterized by dynamically changing network topology due to relative motion of the nodes. This leads to the exchange of large number of control packets between the nodes to maintain the network ...
On wavelets and fractal modulation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
The thesis considers a communication problem - that of communicating over a channel having simultaneously unknown bandwidth and unknown duration. As a solution to this problem, the thesis looks into a modulation scheme - ...
