Recovery From DoS Attacks In MIPv6 : Modelling And Validation
(2010-07-26)
Denial-of-Service (DoS) attacks form a very important category of security threats that are possible in MIPv6 (Mobile Internet Protocol version 6). This thesis proposes a scheme for participants (Mobile Node, Home Agent, ...
Topics In Modeling, Analysis And Optimisation Of Wireless Networks
(2010-11-02)
The work in this thesis is concerned with two complementary aspects of wireless networks research; performance analysis and resource optimization. The first part of the thesis focusses on the performance analysis of IEEE ...
Distributed Joint Source-Channel Coding For Multiple Access Channels
(2010-12-31)
We consider the transmission of correlated sources over a multiple access channel(MAC). Multiple access channels are important building blocks in many practical communication systems, e.g., local area networks(LAN), cellular ...
QoS Aware Quorumcasting Over Optical Burst Switched Networks
(2010-10-11)
Recently there is an emergence of many Internet applications such as multimedia, video conferencing, distributed interactive simulations (DIS), and high-performance scientific computations like Grid computing. These ...
Coplanar Capacitive Coupled Probe Fed Ultra-Wideband Microstrip Antennas
(2010-12-07)
Modern wireless communication systems call for ultra wideband operations to meet the continuous growth in the number of users of these systems. Since antenna is an integral part of any wireless communication system ...
Diversity-Multiplexing Gain Tradeoff Of Cooperative Multi-hop Networks
(2010-08-23)
We consider single-source single-sink (ss-ss) multi-hop relay networks, with slow-fading links and single-antenna half-duplex relay nodes. While two-hop cooperative relay networks have been studied in great detail in terms ...
Diversity-Mutiplexing Tradeoff Of Asynchronous Cooperative Relay Networks And Diversity Embedded Coding Schemes
(2010-08-23)
This thesis consists of two parts addressing two different problems in fading channels.
The first part deals with asynchronous cooperative relay communication. The assumption of nodes in a cooperative communication relay ...
Perceptual Criterion Based Rate Control And Fast Mode Search For Spatial Intra Prediction In Video Coding
(2010-03-11)
This thesis dwells on two important problems in the field of video coding; namely rate control and spatial domain intra prediction. While the former is applicable generally to most video compression standards, the latter ...
