An interactive software environment (CARAT#) that allows rapid prototyping of en route air traffic management algorithms is described. This software employs the NASAFACET software as its computational engine, and allows the user to rapidly develop and evaluate en route air traffic management algorithms. Two versions of CARAT# have been developed. The first is built upon a commercial software pl...

As project, you will extend the application developed last Fall by CS 640 students: Wisconsin Netpy. It is an Internet traffic analysis and visualization application using NetFlow data collected by routers. This description of the project assumes that there will be four teams working on different parts of the project. Currently Netpy is divided into three main components: the database, the anal...

Distributed Denial-of-Service attacks are an effective means to make a service unavailable, mask other attack activities and generally degrade or disrupt network functionality. The key characteristic is that analysis of and defence against this attack type is difficult because of the high number of attacking hosts and large amount of attack traffic that can be generated. The emerging Peer-to-Pe...

The authors propose a real-time adaptive signal control model that aims to maintain the adaptive functionality of actuated controllers while improving the performance of traffic-actuated control systems. In this model, a flow-prediction algorithm is formulated to estimate the future vehicle arrival flow for each signal phase at the target intersection on the basis of the available signal-timing...

We study the problem of distributed resource sharing in peer-to-peer networks and focus on the problem of information filtering. In our setting, subscriptions and publications are specified using an expressive attribute-value representation that supports both the Boolean and Vector Space models. We use an extension of the distributed hash table Chord to organise the nodes and store user subscri...

In this paper, we propose an N × N high speed and non-blocking asynchronous transfer mode (ATM) switch with input and output buffers. In this switch, each buffer adopts a priority discarding scheme, which discards incoming cells of low-priority traffic when its queue length is greater than a predefined threshold value. Our switch also supports broadcast/multicast functions without increasing th...

Wireless Sensor Network is one of the emerging and latest research areas which are used to scan and analyze surrounding state like sound, light, pollution, temperature, wind speed, humidity, pressure, direction etc. WSNs are also used in a variety of application areas like traffic scanning, industrial scanning, machine health monitoring, traffic monitoring etc. Cluster-based WSN gives benefits,...

This paper proposes a new energy management framework for an IP over WDM network. A key constraint of our architecture is to maintain the logical IP topology while saving energy by infrastructure sleeping and virtual router migration. Since the traffic in a network typically has a regular diurnal pattern based on people’s activities, some virtual routers can be moved to a smaller set of physica...

As the number of users increased over years, pioneering technologies and solutions in given areas ceased to be sufficient even terms performance. Therefore, there was a need for their development or redesign redefinition. One issues that undoubtedly has huge impact on current shape global network way information is processed it issue traffic balancing, especially one server infrastructure relat...

In recent years, mobile communication traffic has continuously been shifting from being dominated by voice-call traffic with symmetric uplink / downlink capacity requirements to burst-like traffic with strongly fluctuating capacity requirements depending on instantaneous file upload / download activities by mobile users. Consequently, LTE, which was originally designed with fixed FDD or TDD mod...
