Vehicle traffic congestion leads to air pollution, driver frustration, and costs billions of dollars annually in fuel consumption. Finding a proper solution to vehicle congestion is a considerable challenge due to the dynamic and unpredictable nature of the network topology of vehicular environments, especially in urban areas. Instead of using static algorithms, e.g. Dijkstra and A*, we present...

A Wireless Sensor Network (WSN) consists of one or more sinks and large number of sensor nodes scattered in an area. It is a collection of sensor nodes are interconnected by wireless communication channels. Wireless sensor networks will be used for such tasks as surveillance, widespread environmental sampling, security and health monitoring. With this data simple computations are carried out an...

Abstract. The operation of the urban traffic exist a high degree of complexity and randomness. The key of Intelligent Transportation System is the real-time and accurate traffic flow prediction. Taking effective measures in a timely manner would prevent the occurrence of traffic accidents since traffic congestion brings much traffic inconvenience to people. Real-time traffic flow prediction pla...

Transport network pricing is a topic of interest to transport planners and users alike. Pricing schemes are a vital traffic management strategy which can be implemented to reduce congestion, among other network externalities. Previous research has explored pricing schemes to achieve a variety of network objectives, including social and environmental concerns. This work introduces a robust strat...

In Wireless Sensor Networks (WSN) the packet loss occurs due to congestion. The sink node which is called special node collects information from other nodes. There are various congestion control algorithms are currently used. In WSN congestion detection and congestion control are the major research areas. It is important to design protocols for controlling congestion. The congestion control pro...

We study traffic congestion by analyzing a one dimensional traffic flow model. Developing an asymptotic method to investigate the long time behavior near a critical point, we derive the modified Korteweg-de Vries (mKdV) equation as the lowest order model. There are an infinite number of kink solitons to the mKdV equation, while it has been found by numerical simulations that the kink pattern ar...

Congestion control ensures that network resources are divided fairly and efficiently among competing connections. Although congestion control has been studied by researchers for a long time, very high-speed networks using ATM pose a new set of challenges. The proposed credit-based mechanism provides flow control tailored to ATM networks. Simulation, analysis and experiments on switching hardwar...

Asynchronous transfer mode (ATM) is a networking protocol intended to support applications with a variety of different service requirements. Traffic management is needed to ensure that the network's resources are not overloaded and that the traffic receives its desired service. One proposed method of traffic management for non-real time, data traffic is 'rate based' congestion control. In this ...
