On the basis of the continuous traffic noise data observed at 142 sites distributed in 52 roads from 1989 to 2003, the characteristics of traffic noise and effect factors were analyzed through traffic noise indices, such as Lep, L10, L50, L90, TNI, and Pn. Our findings allow us to reach a number of conclusions as follows: Firstly, traffic noise pollution was serious, and its fluctuant character...

This paper presents a model for interdomain traffic simulation at the flow level. The model explicitly takes into account three network-related variables for the traffic generation process: the arrival process of the layer-4 flows, the traffic volume carried over these flows and the rate at which these flows can send traffic. The variables of the model are first analyzed on a real flow-level in...

Network-based detection of botnet Command and Control communication is a difficult task if the traffic has a relatively low volume and if popular protocols, such as HTTP, are used to resemble normal traffic. We present a new network-based detection approach that is capable of detecting this type of Command and Control traffic in an enterprise network by estimating the trustworthiness of the tra...

The Problem Urban areas face increasingly acute vehicular traffic congestion. Current methods for measuring traffic flow on a real-time basis are antiquated and limited in their capacity to assess traffic dynamics. Buried inductive loop detectors at intersections are extensively used in the USA and Europe to measure traffic speed, occupancy and volume on freeways and arterials. The data obtaine...

In recent years, the volume of traffic is rapidly increasing. When vehicles running through the tunnel are more intensive or move slowly, the tunnel environment occurs deteriorated sharply, which affects the normal operation of the vehicle in the tunnel. This paper uses the result of previous mining association rules to select feature items and to establish four training samples divided by time...

The advent of Multi-protocol Label Switching (MPLS) enables traffic engineering by introducing connection-oriented features of forwarding packets over arbitrary non-shortest paths. Our goal in this research is to improve the network utilization for best effort traffic in IP networks. By examining the best effort traffic class, we assume the large volume of research that has been conducted on tr...

TCP traffic has been reported to have not only self-similarity but multi-fractal nature. Multi-fractal nature of traffic volume, in general, is well known to have significant influence to queueing behavior in short time scale. In the paper, we investigate about ”what component of TCP congestion control mechanism affects to multifractal nature of generated traffic?”. We artificially divide TCP c...

Understanding the machine-type communication (MTC) traffic is a key for designing and optimizing a network and the applicable QoS scheme capable of providing adequate communication services without compromising the conventional services such as data, voice, and video. In this paper, we propose a framework for traffic modeling, generation, and load estimation for machine-type communication that ...
