Traffic engineering and QoS Fguarantee is crucial point of any operators’ network. To evaluate IMS services over MPLS enabled network in case study, we have created a testbed for a service provider. Our service provider distributes various services requiring different traffic priorities together with customer-generated traffic. We have enabled the IMS core to trigger associations based on custo...

Travels within the city are done in different ways, by vehicle or on foot. Thus, inevitably, a part of the travel is always done on foot. Since intersections as traffic nodes are determinant factor in transportation network capacity, any disruption in them leads to severe reduction in network capacity. Unfortunately, pedestrian behavior has received little attention in Iran. While this is a ver...

car accidents are documented as a growing public health problem in iran as well as other developing countries. generally growing number of population and vehicles are not accompanied by extending road construction programs. these could be result in high death, disability, and economic loss in such country compare to develop one. this mainly affected young person who are economically more active...

Today’s information society relies increasingly on advanced communication networks. This has lead to massive investments in increased communication network capacity. In order to utilize these investments the network operators perform traffic engineering, i.e., route communication in order to maximize the utilization of the capital invested in the communication network. Here we will consider tra...

This paper presents an autonomous traffic engineering framework, named ATE, a highly efficient data dissemination mechanism for multipath data forwarding in Wireless Sensor Networks (WSNs). The proposed ATE has several salient features. First, ATE utilizes three coordinating schemes: an incipient congestion inference scheme, an accurate link quality estimation scheme and a dynamic traffic diver...
