Spectral graph theory analysis of software-defined networks to improve performance and security
Software-defined networks are revolutionizing networking by providing unprecedented visibility into and control over data communication networks. The focus of this work is to develop a method to extract network features, develop a closed-loop control framework for a software-defined network, and …

Network Models In Evacuation Planning
… addresses the development and analysis of optimization models for evacuation planning. Specifically we consider the cases of large-scale regional evacuation using household vehicles and hospital evacuation. Since it is difficult to estimate the exact number of people evacuating, we first …

A Study of the Capacity Drop Phenomenon at Time-Dependent and Time-Independent Bottlenecks
The fact that traffic congestion upstream of a bottleneck causes a reduction in the discharge flow rate through the bottleneck has been well documented in several empirical studies. However, what has been missing is an understanding of the causes of these empirically observed flow reductions. An …

Performance modelling and analysis of congestion control mechanisms for communication networks with quality of service constraints. An investigation into new methods of controlling congestion and mean delay in communication networks with both short range dependent and long range dependent traffic.
… (AQM) schemes are used for ensuring the Quality of Service (QoS) in telecommunication networks. However, they are sensitive to parameter settings and have weaknesses in detecting and controlling congestion under dynamically changing network situations. Another drawback for the AQM algorithms is …

Freeway Travel Time Estimation Based on Spot Speed Measurements
As one of the kernel components of ITS technology, Travel Time Estimation (TTE) has been a high-interest topic in highway operation and management for years. Out of numerous vehicle detection technologies being applied in this project, intrusive loop detector, as the representative of spot …
