Overview
The Center is involved in five areas of research: Network Congestion, , Economics of Network Congestion, Heavy Tails, and Rare Events Simulation. Our efforts in Network Congestion research are focusing on finding solutions to packet loss, Quality of Service, latency and jitter problems introduced when IP networks become overloaded. Investigation into Network Resiliency involves determining how well a network may be able to absorb widespread damage before significant mission effectiveness is lost. Our investigations surrounding the economics of network congestion are currently focused on assessing likely congestion conditions and toll revenue projections when travel reliability is established as the foundation for financial transactions between transportation system user and transportation system operator. Our research in Heavy Tails Distributions Modeling investigates the feasibility of various approaches to modeling queues with heavy-tailed interarrival and service distributions. Our research in Rare Events Simulation is to develop new approaches for simulating rare events and to efficiently determine via simulation the best choice among a number of alternatives, where the simulation of each alternative requires the evaluation of a rare-event probability.
