Over the last few years, a worryingly number of attacks against SSL/TLS and other secure channels have been discovered. Fortunately, at least from a defenders perspective, these attacks require an adversary capable of observing or manipulating network traffic. This prevented a wide and easy exploitation of these vulnerabilities. In contrast, we introduce HEIST, a set of techniques that allows u...

This paper introduces a new application of genetic algorithm (GA) in dynamic sector synthesis of antenna array for mobile base transceiver station (BTS). The basic objective is to have narrow beam widths in heavy handoff areas and wider beam widths in areas with low traffic density. By predefining the beam widths and thus the beams of each sector, optimal sectoring can be achieved using GA at d...

Dynamic wavelength assignment in a WDM all-optical network with partial and sparse wavelength conversion is discussed in this paper. The performance of unidirectional and bidirectional ring networks in terms of blocking probability, conversion gain and fairness is evaluated under various types of offered traffic patterns. Smooth and peaked patterns have been considered in addition to the classi...

The mitigation potential of avenue tree species needs a sound understanding, especially for landscape planning or planting tree species on roadside, especially in city limits where there is huge traffic due to more number of vehicles. A preliminary study was conducted to investigate the impact of heavy traffic movement and pollution thereof on physiological functioning of Lagerstroemia speciosa...

This paper describes a set of tools and techniques to capture and analyse virus-generated IP network traffic. We analyse seven viruses, worms, trojans and spyware that are common in Microsoft Windows environments. We log and analyse the IP traffic generated in the roughly 2 hours after each infection. Based on the resulting IP traffic patterns we estimate the likely financial impact of having a...

Network operators control the flow of traffic through their networks by adapting the configuration of the underlying routing protocols. For example, they tune the integer link weights that routing protocols like OSPF use to do distributed forwarding of packets. The resulting optimization problem by the operator—to find the best link weights for a given topology and traffic matrix—is well-known ...

Traffic induced turbulence coupled with natural air motions becomes an important variable affecting the dispersion of exhaust emissions, especially under low wind conditions. A flexible model vehicle movement system (ƒMVMS) for an urban intersection having two-way straight and radial peripheral traffic flows has been designed, fabricated and made operational in the EWT to study the traffic indu...
