In this paper, we propose a two-step unlinkability measuring approach for MANET, i.e., (a) evidence collection using statistical packet-counting traffic analysis, (b) evidence theory-based unlinkability measure. We use IEEE 802.11b-based MANETs as our analytical systems. Using our approach, we can collect a set of evidence to set up a probability assignment for each possible communication relat...

obviously, improving the road safety and the efficient allocation of limited resources to the provinces according to their ranking should be done. this paper presents a hybrid method of multivariate statistical analysis-decision making to evaluate iran road traffic safety. in order to solve the problems of road traffic safety, a macroscopic evaluation and traffic safety level classification in ...

monitoring of road traffic noise is becoming an important issue in modern cities due to the spreading of noise pollution and the extension of monitored areas. thus, the stratified spatial sampling is frequently applied to reduce the costs and provide adequate accuracy in order to obtain reliable noise maps. the definition of the strata in the sampling may refer to the legislative classification...

background: injuries and deaths from road traffic crashes are one of the main public health problems throughout the world. this study aimed to identify determinants of fatality traffic accident in iran for the twenty-span year from 1991 to 2011. methods: a time series analysis (1991-2011) was used to examine the effects of some of the key explanatory factors (gdp per capita, number of doctors p...

today, the motorcycle riders in the streets as traffic congestion have become a challenge. if we do not have planning and scientific management for this problem, consequently the volume of traffic and accidents, crime, social damages will be increased. considering the importance of the issues, identify and assess the factors promote traffic safety, reduce crime and social problems with motorcyc...

As more drivers use the roadways in the U.S. and abroad, traffic problems only become more important to understand and, hopefully, resolve. Among the long list of traffic problems, traffic jams are quite near the top. The ”shockwave traffic” theory has emerged recently as a promising way to model the propagation of these traffic jams by describing them as waves.[1] In this theory, the shockwave...

In this paper we present a concept of new architectural model consisting of multiple loop delay to increase the throughput. The simulated behavior of an optical node has been realized by using an n x m optical switch and recirculating optical delay lines. This investigation infers the scaling behaviors of the proposed architecture to maintain efficient use of the buffer under Poisson traffic lo...
