Network monitoring guides network operators in understanding the current behavior of a network. Therefore, accurate and efficient monitoring is vital to ensure that the network operates according to the intended behavior and then to troubleshoot any deviations. However, the current practice of network-monitoring largely depends on manual operations, and thus enterprises spend a significant port...

Increasing usage of Internet and computer networks by individuals and organizations and also attackers’ usage of new methods and tools in an attempt to endanger network security, have led to the emergence of a wide range of threats to networks. A honeypot is one of the basic techniques employed for network security improvement. It is basically designed to be attacked so as to get the attackers’...

Proper design and operation of monitoring systems for water resources management is one of themost important issues of water quality and quantity and accuracy and adequacy of data. The properevaluation of these data has a determining role in the correctand consistent decisions in the areacovered by the system. Therefore, determining proper distribution and number of monitoringnetwork stations a...

An intelligent method based on wavelet neural network (WNN) is presented in this study to estimate voltage harmonic distortion waveforms at a non-monitored sensitive load. Voltage harmonics are considered as the main type of waveform distortion in the power quality approach. To detect and analyze voltage harmonics, it is not economical to install power quality monitors (PQMs) at all buses. The ...

Korea has been operating groundwater monitoring systems since 1996 as the Groundwater Act enacted in 1994 enforces nationwide monitoring. Currently, there are six main groundwater monitoring networks operated by different government ministries with different purposes: National Groundwater Monitoring Network (NGMN), Groundwater Quality Monitoring Network (GQMN), Seawater Intrusion Monitoring Net...

Wireless Mesh Networks (WMN) have emerged as a potential technology to quickly deploy a wireless infrastructure that is selfhealing, self-configured, and self-organized. This report makes an introduction to WMNs, their protocols and some existing deployments. Then the problem of monitoring the operation of these networks, is addressed by making a brief survey on some relevant network monitoring...

Intrinsic Monitoring is a method of collecting and disseminating node specific monitoring data throughout an IPv6 network by using the IPv6 extension headers as a carrier medium. The advantages of such a monitoring mechanism can be invaluable to a network operator, offering a wide range of performance and accuracy enhancements over traditional SNMP based or active probing based approaches. This...

One of the existing problems of multi-attribute process monitoring is the occurrence of high number of false alarms (Type I error). Another problem is an increase in the probability of not detecting defects when the process is monitored by a set of independent uni-attribute control charts. In this paper, we address both of these problems and consider monitoring correlated multi-attributes proce...

pollution control is based on correctly measuring pollutant concentrations but, at the moment,the principal european cities only monitor pollution levels by means of a few fixed stations co-located inselected points of the urban layout far from hotspots and/or by means of meteorological prediction models offuture pollution. few cities integrate the information from both sources. the implementat...
