moving toward third millennium is characterized by capabilities in transforming human life. specially, development of information technologies in everyday life lead to great changes in communication tools andour current understanding ofurban social life. indeed, telecommunications because of independency from time—space constraints, provide a new unlimited space for social interactions in globa...

Cross-sector competition in the information and communications technology sectors (ICT sectors) constitutes a key strategic challenge for telecommunications companies. Due to increasing convergence, value creation is resulting in a greater degree of interaction. The diversification potential of telecommunications businesses is therefore changing with respect to associated ICT sectors, such as h...

Communication facilities can totally be destroyed by natural and / or manmade disasters. A critical problem after disaster is getting the first hand knowledge of the destructions and also establishing some communication links among the survivors. This paper focuses on the vital need for providing communications facility to the victims, immediately after the disaster and prior to the arrival of ...

New open service architectures provide a management framework for telecommunications services, telecommunications networks and computing resources. However, the introduction of multimedia applications in these architectures will require the management of the underlying multimedia resources (e.g., codecs, converters, etc). Multimedia resources are the basic components that support multimedia com...

Throughout the history of communications systems, fault tolerance and other means to building resilient platforms were the exclusive and proprietary purview of Telecommunications Equipment Manufacturers (TEMs) and, more recently, Network Equipment Providers (NEPs). After the “dark ages” of telecom in the late 1990s, telecommunications system design began to experience a renaissance with ever-in...

In this paper we propose a new formulation for the bandwidth packing problem (BWP) in telecommunications networks. This problem is one of selecting calls, from a list of requests, to be routed in the telecommunications network. We consider both revenue losses and costs associated with communications delay as parts of the objective. An ecient Lagrangean relaxation based heuristic procedure for ...

In telecommunication a Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor .Wireless operations permit services, such as long-range communications, that are impossible or impractical to implement with the use of wires.
