We consider the important practical and theoretical problem of designing a low-cost communications network which can survive failures of certain network components. Our initial interest in this area was motivated by the need to design certain “twoconnected” survivable topologies for fiber optic communication networks of interest to the regional telephone companies. In this paper, we describe so...

The main concern in modern chip design is definitely the communication structure that connect the components. Chip complexity is increasing constantly, making a chip look like a distributed set of communicating entities. In this paper a formal framework for the synthesis of an optimum onchip communication network is proposed. The major differences between network design and on chip network desi...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...

This paper presents a new method for the estimation and characterization of the expected teletraffic in mobile communication networks. The method considers the teletraffic from the network viewpoint. The traffic estimation is based on the geographic traffic model, which obeys the geographical and demographical factors for the demand for mobile communication services. For the spatial teletraffic...
