الحاق و پیوند ترافیک از جفت فرستنده-گیرنده های مختلف به مسیر نوری پرظرفیت ، آرایش ترافیک یا همان traffic grooming نامیده می شود. در این پایان نامه، به بررسی و ارائه الگوریتمی جهت آرایش ترافیک (traffic grooming) در شبکه های ip-over-wdm می پردازیم که برپایه بهینه سازی به روش کلونی مورچه ها (acs) بنا شده است و از تابع احتمالی که به دو پارامتر هزینه و مقدار فرومون وابسته است استفاده می کند. در ادا...

Background and aim: Air traffic control has known as a complex cognitive task, which requires controller to focus on task for long time. Mental workload plays an important role in the performance of controllers. The aim of this study was to assess the workload of air traffic controller on the basis of task load factors. Methods: The present descriptive-analytical study was conducted among fo...

The performance of many traffic control strategies depends on how much the traffic flow models have been accurately calibrated. One of the most applicable traffic flow model in traffic control and management is LWR or METANET model. Practically, key parameters in LWR model, including free flow speed and critical density, are parameterized using flow and speed measurements gathered by inductive ...

short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. the strong need to monitor and control congestion time and costs for metropolis in developing countries has therefore motivated the current study. this paper establishes the applicatio...

Currently used traffic control measures, such as traffic signals, variable speed limits, ramp metering installations etc., are often not designed to influence the route choice of drivers. However, traffic control measures do influence the travel times that are experienced in the network. Since route choice is, at least for a part, based on experienced travel times, the control measures thus als...

Knowledge of flow distributions from a stream of packets passing through a network link helps a network operator infer traffic demands, characterize source traffic, and detect traffic anomalies. Flow monitoring provides critical information for many network applications, and some approaches have been proposed to address flow monitoring. However, they either lack accuracy, or require intensive c...
