Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

IYER, VIJAY R. A Simulation Study of Wavelength Assignment and Reservation Policies with Signaling Delays. (Under the direction of Professor George N. Rouskas). This thesis studies the effect of non-negligible signaling delays on the performance of wavelength-assignment heuristics, wavelength reservation schemes, routing schemes, holding time (average being 1/μ) of the lightpaths and traffic lo...

The paper deals with simulation of congested road networks through dynamic traffic assignment models and presents a new quasi-dynamic traffic assignment model that improves realism and effectiveness of both usual static traffic assignment models and other quasi-dynamic models recently introduced in the literature, as it simulates flow progression onto the network by moving link flows according ...

This paper reports on the evaluation of alternative algorithms for dynamic, or time-varying, equilibrium traffic assignment. The algorithms are used for pre-trip assignment, which reflects driver familiarity with expected traffic conditions, and are appropriate for off-line applications which require a more detailed analysis – such as temporal network flows and sensitivity to traffic control me...

—Efficient management of the radio spectrum can be accomplished by making use of channel assignment techniques, which work by allocating different channels of the spectrum to the cells of the network in a conflict-free manner (i.e., the cochannel interference is minimized). The problem of dynamically reallocating the channels in response to change in user location patterns, which occurs frequen...

Today, IEEE 802.11 wireless LANs (WLANs) are widely deployed throughout the world. It is known that static channel assignments are not sufficient for these networks due to traffic variations. However, in order to maintain compatibility with the existing protocol standards, it is not possible to employ dynamic channel allocation methods to handle traffic-load fluctuations. Rather, adaptive assig...
