In an opportunistic network (OPPNET), the forwarding schemes for adhoc networks are not applicable since there is no complete path between the source and the destination node and relay nodes should store messages when no forwarding opportunity exists. Recently several proper schemes have been proposed in an OPPNET. Among them, floodingbased schemes result in very high network traffic and low tr...

Earthquakes are among those natural hazards which may lead to disruption in the function of arterial traffic routes. Road networks are particularly vulnerable, due to their geographical dispersion, extensive functions and structural reliance on favourable geophysical conditions. Traffic functionality after a natural disaster and the repair/rehabilitation cost of roads are crucial considerations...

In recent years, flexible manufacturing system as a response to market demands has been proposed to increase product diversity, optimum utilization of machines andperiods of short-term products.The development of computer systems has provided the ability to build machines with high functionality and the necessary flexibility to perform various operations. However, due to the complexity and the ...

Traffic Management involves planning, designing, integration of traffic signal system to achieve efficiency, safety, reliability. Designing of signal system which will provide real time feedback of traffic conditions for dynamic functionality to control traffic signals to optimize traffic management. In this paper, I have used Infrared Transceivers (sensors) for collecting real time data and Mi...

Bittorrent currently makes up a large proportion of Internet traffic. The main purpose of my project is to attempt to identify Bittorrent traffic from other kinds of traffic (with particular emphasis on FTP which provides similar functionality to BitTorrent in that it is primarily used for large file downloads) using statistical classification techniques. I will show that Bittorrent traffic can...

Intelligent Transportation System (ITS) is one of the most important urban systems that its functionality affects other urban systems directly and indirectly. In developing societies, increasing the transportation system efficiency is an important concern, because variety of problems such as heavy traffic condition, rise of the accident rate and the reduced performance happen with the rise of p...

The introduction of advanced Air Traffic Management (ATM) functionality is often heralded as a safety improvement. On the whole, the introduction of advanced ATM functionality will probably reduce the likelihood of an accident. However, its introduction may also entail new sources of safety risk that need to be carefully weighed against the safety benefits of advanced ATM functionality. Many ne...

This paper proposes a novel approach for introducing programmable functions into Internet-type networks. Specifically, the functions are designed to improve the quality of multiple video conferencing sessions when transmitted over DiffServ-enabled IP networks. The scheme operates through the use of the IPv6 hop-by-hop option header. Detailed simulations are presented that show how incorporating...
