An active queue management scheme to contain high bandwidth flows at a congested router
(Texas A&M University, 2001)
Incorporating mechanisms in the router to enable end-to-end congestion control is important in order to prevent the network collapse. Routers should be able to recognise misbehaving flows and penalise them. In this ...
Machine learning approaches to biochemical knowledge discovery
(Texas A&M University, 2001)
In the biological sciences, there has been a tremendous growth in the amount of data generated by scientists, from the sequencing of DNA to the determination of three-dimensional structures of proteins. Due to the size ...
Delayed response protocols for high-delay wireless networks
(Texas A&M University, 2002)
Wireless networks have become more prevalent over the last few years. These networks introduce different types of errors, which are due to the unpredictable nature of the wireless channel. The congestion control algorithms ...
High performance parallel algorithms for incompressible flows
(Texas A&M University, 2002)
The generalized Stokes problem, which arises frequently in the simulation of Navier-Stokes equations for incompressible fluid flow, gives rise to symmetric linear system of equations. These systems are indefinite because ...
The use of a simple cellular automata model as a testbed for kinetic theories of vehicular traffic flow
(Texas A&M University, 2000)
The broad objective of this thesis is to explore the potential for the use of Cellular Automata (CA) models to provide a testbed for comparison of different kinetic models of vehicular traffic. We intend to develop a ...
A general performance model for parallel sweeps on orthogonal grids for particle transport calculations
(Texas A&M University, 2000)
There is a growing need to accurately simulate physical systems whose evolution depends on the transport of subatomic particles. It has long been recognized that the huge computational demands of the transport problem ...
Anti-eavesdropping communication layer to protect against traffic analysis
(Texas A&M University, 2002)
In this thesis, we present unicast and multicast protocols to resist eavesdropping and traffic profiling of group communications. At the application layer, we propose a secret-sharing approach for the exchange of shared ...
Simulation-based comparison of TCP retransmission timeout estimators
(Texas A&M University, 2000)
The implementation of the retransmission timeout estimator for TCP re-initializes the timer with the retransmit timeout (RTO) after receiving an acknowledgement (ACK), if any more segments are in flight. This allows an ...
A framework for delay emulation of large-scale internetworks
(Texas A&M University, 2001)
Several network applications require access to a large number of geographically distributed machines for testing and debugging purposes. Typically, it is the case that either access is not available for so many machines, ...
Walden's authoring tools: a usability evaluation
(Texas A&M University, 2000)
Walden's Paths enables K-12 teachers to incorporate Web-based information in their curriculum. However, most information on the Web requires some tailoring or contextualization in order to adapt it for curricular purposes. ...
