Physical and logical mobility of CORBA servants under intermittent connectivity nomadic environments
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
In a wired environment, object-oriented middleware facilitates the development of distributed objects. Common Object Request Broker Architecture is a prominent example of object-oriented middleware. As a joint effect of ...
Processor allocation for parallel applications in computing cluster
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
We study the problem of processor allocation in multi-computer for parallel processes that do I/O and IPC (Inter Process Communication). A simulator has been modified to accept synthetic parallel workload that does I/O and ...
Design of frequency synthesizable delay locked loop
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
As the speed performance of VLSI systems increases rapidly, more emphasis is placed on suppressing skew and jitter in the clocks. Phase-locked loops (PLLs) and delay-locked loops (DLLs) have been typically employed in ...
Covert communication in TCP/IP network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
This thesis explores the area of Covert Communication in TCP/IP network (Internet). We investigate various protocols of TCP/IP suite, which have potential to be used for covert communication on the network. In this thesis ...
Energy efficient secret aggregation for wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Sensor networks involves large amount of nodes spread over a region. Data aggre¬gation is an important technique for reducing the amount of data to be transmitted in the networks. Data confidentiality is a crucial requirement ...
Design and implementation of a framework for context aware mobile services
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Applications designed for mobile platforms are traditionally hampered by the limita¬tions of the client devices, in particular limited user interface and the change of user environment due to mobility. Incorporating location ...
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 ...
Fractal based approach for image segmentation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
In this thesis, we have proposed an algorithm for image segmentation, using the fractal codes. The basic idea behind this algorithm is to use fractal codes for the image segmentation. This method uses compressed codes ...
Performance analysis of MPEG traffic under deficit round Robin Scheduler
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
The use of network multimedia applications like Video Conferencing and Video-on-Demand is likely to increase tremendously in future. Bandwidth, delay and delay variation are important performance parameters in such ...
Improved algorithms for modular multiplication and its application to block cipher RC6
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
This thesis explores the area of hardware implementation of block ciphers. An al¬gorithm for modular multiplication is proposed which is efficient in terms of speed and area. To demonstrate the effectiveness of the algorithm ...
