In view of the ever-increasing air traffic, much attention in air-traffic-management research has been given to improving arrival and departure efficiency. As air traffic begins and ends at the airport, the issues of taxi delays and ground-operation incursions become more pressing. This paper considers the surface-traffic problem at major airports and envisions a collaborative traffic and aircr...

Massive growth of the Internet traffic in last decades motivated the design of high-speed optical network for traffic aggregation from different access technologies. The network architecture proposed in this paper is a low-cost flexible solution consisting of two dual buses located over a physical bidirectional ring network topology. OTDM technology is used for statistical traffic multiplexing ...

A human-in-the-loop experiment was conducted at the NASA Ames and Langley Research Centers, investigating the En Route Free Maneuvering component of a future air traffic management concept termed Distributed Air/Ground Traffic Management (DAG-TM). NASA Langley test subject pilots used the Autonomous Operations Planner (AOP) airborne toolset to detect and resolve traffic conflicts, interacting w...

Network traffic dynamics have become an important behavior-based approach to assist security administrators in protecting networks. In this paper we present VisFlowConnect-IP, a link-based network flow visualization tool that allows operators to detect and investigate anomalous internal and external network traffic. We model the network as a graph with hosts being nodes and traffic being flows ...

Congestion avoidance techniques for event builders using switching network technologies is a major issue. Traffic management of the data flow is an essential point to avoid congestion. Global traffic control is one of the mechanisms to manage the traffic. It uses global information of the switching network. While, traffic shaping technique is another mechanism not to use them. Quality of Servic...

Most applications built upon vehicular communications (V2X) target on increasing traffic safety. They often require a direct communication between at least two vehicles equipped with a communication device. Thereby, a sufficient amount of equipped vehicles is necessary for assuring these applications’ functionality. Meanwhile, traffic management needs information about the state on the roads. T...

This demo combines active DB technology in open, heterogeneous environments with the Web presence requirements of nomadic users. It illustrates these through profiling of users and Internet-enabled vehicles. A scenario is developed in which useful functionality is provided, such as instrument adjustments, maintenance and diagnostic information handling with the corresponding workflows, and conv...

This paper illustrates both the detailed theoretical setup of the Interconnection Border Gateway Function (IBGF) and its technical implementation using Open Source Software components. Moreover, a model is proposed to handle different traffic classes according to their corresponding Quality of Service (QoS) requirements while also forwarding ”best effort” data traffic. The functionality is veri...
