MAGNET II is a testbed for integrated networks. It was designed and implemented based on requirements of real-time network management and control. Quality of service requirements explicitly appear in the design speci cations of the network on the media access level. Switching is based on the concept of Asynchronous Time Sharing. The core of the network distinguishes between three tra c classes....

This paper discusses the future trends on teleteaching applications. These include remote access to distributed virtual reality resources, information on demand teleservices and multimedia telecommunication environments across high speed multicast networks for teleteaching scenarios. A teleteaching session held by a lecturer in Berlin is multicasted across the regional metropolitan area network...

The objective of the present study is to design and develop an Artificial Neural Network (ANN) model for estimations of the ambient ozone concentrations based on meteorological and pollutant parameters. The study focuses on an urban site in the metropolitan area of Athens. The research proves that the optimal ANN is a Modular one that uses the Back Propagation Optimization Algorithm. This ANN i...

We propose a novel hybrid optical wireless access network architecture that is designed for highly populated metropolitan area. This hybrid access network consists of an optical grid network providing broadband backhauling, and many wireless mesh networks penetrating into the neighborhoods to provide low cost, ubiquitous links. This hybrid access network architecture is scalable and flexible en...
