There is a need to back up critical timing infrastructure at the national level. This paper describes a joint project employing commercial equipment to send national timing signals through a telecommunication network. This experiment connects UTC(NIST) in Boulder, Colorado with UTC(USNO) at the Alternate Master Clock at Schriever AFB via a telecommunication provider's optical network using the ...

We consider spatial stochastic models, which can be applied e.g. to telecommunication networks with two hierarchy levels. In particular, we consider Cox processes XL and XH concentrated on the edge set T (1) of a random tessellation T , where the points XL,n and XH,n of XL and XH can describe the locations of low–level and high–level network components, respectively, and T (1) the underlying in...

Next-generation networks, including the Internet of Things (IoT), fifth-generation cellular systems (5G), and sixth-generation (6G), suffer from dramatic increase number deployed devices. This puts high constraints challenges on design such networks. Structural changing network is one that affect performance, required quality service (QoS). The fractal dimension (FD) considered main indicators ...

A wide range of security services may be available to applications in a heterogeneous computer network environment. Resource Management Systems (RMSs) responsible for assigning computing and network resources to tasks need to know the resource-utilization costs associated with the various network security services. In order to understand the range of security services an RMS needs to manage, a ...

Wireless networks are becoming more and more popular and traffic over the networks is growing rapidly. Because the network infrastructure is expanding at a quick pace, especially the wireless Internet growth , both in size and in the types of applications, the performance issue and dimensioning issue of networks are becoming more critical. New wireless data applications are emerging over mobile...

network effects, increase in the value of consuming a product if many other consumers use the same product, is a feature of many markets of high-technology products. frequently cited examples of products exhibiting network effects are telecommunication or software products. this research explores the role of network effects in the consumer´s choice of mobile operator in tehran. for our empirica...

The digital revolution holds great promise for prosperity and progress. However, the Information Society evolution is supported through the telecommunication networks deployment. The high cost of such infrastructures forces the companies to focus their efforts in the profitable society sectors. For that, the promotion of performances to bridge the digital divide between rural and urban areas ap...
