This paper focuses on two aspects of photonic network traffic performance investigation. Two different modelling approaches for the evaluation of network nodes under dynamic traffic conditions are described. This allows to evaluate how suitable different node architectures are for networks carrying dynamic traffic. Furthermore, routing strategies are becoming more important with increasing dyna...

This article addresses the problem of simulating en-route path choices on transport networks. In particular, by rerouting, we mean changing the currently chosen path, after receiving some information about a traffic event. Indeed, when the forecasted performance pattern of travel times and costs, known or only perceived, changes significantly, drivers may react by shifting their current route t...

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...

Problem statement: WiMAX supports multiple types of traffic such as data, voice and video. Each flow requires a certain minimum bandwidth to achieve its QoS. Bandwidth allocation to traffic classes should be in such a way that fairness criteria is met with. Hence, we propose a dynamic bandwidth allocation mechanism to achieve fair and efficient allocation. Approach: We present a Generalized Sto...

This paper proposes a novel dynamic bandwidth assignment multiple access (DBAMA) protocol employing a dynamic packet reservation technique for direct user terminal access to a ATM-based low earth orbit (LEO) satellite communications system. Performance analyses by simulations are presented. Methods to efficiently integrate ATM-based BISDN traffic are considered.

For a static/dynamic O-D matrix estimation, usually, the basic required information is a starting estimation of O-D matrix and a set of traffic counts. In the era of the Intelligent Transportation Systems, a dynamic estimation of traffic demand has become a crucial issue. Different Dynamic Traffic Assignment (DTA) models have been proposed, used also for O-D matrices estimation. This paper pres...
