A user-defined telecooperation service (UTS) provides service elements for application-specific communication and cooperation processes as well as integrated means for the service definition, adaption, and management. It supports user groups with particular communication, cooperation, and coordination needs which may change over time and which may be that special, that the service maintenance c...

Telemedicine provides medical information and services using telecommunication technologies. It includes systems for remote clinical care and consultation through the use of electronic imaging equipment. In wireless telemedicine, broadband multimedia information that is a combination of video, audio and externally acquired images is transmitted. Emergency medicine helicopters take an important ...

Building new UMTS (Universal Mobile Telecommunication Systems) based networks seems to be on time. Nowadays the UMTS network design related problems are moving to the interconnection of Radio Network Controllers (RNC), placement of Media Gateways (MGw) and planning of the core network topology. This new area of UMTS network design is studied in the paper. A new algorithm is proposed for the abo...

Two Large-Scale Network Design Problems In this work we consider two large-scale network design problems arising in network routing and provisioning. The first problem combines long-term business and design decisions on large-scale telecommunication networks. The problem integrates different elements of network business planning such as capacity expansion, routing and protection and equipment m...

The overall aim of this project was to ascertain the utilization of a custom-designed telemedicine service for patients to maintain close contact (via videoconference) with family and friends during hospitalization. We conducted a retrospective chart review of hospitalized patients (primarily children) with extended hospital length of stays. Telecommunication equipment was used to provide video...

Digital image processing has important in many areas such as digital telecommunication, remote sensing, robotics, graphic printing, and medical imaging, defense and security applications[1]. During the transmission and acquisition, images are corrupted by the different type of noise. Because of the noise, quality of image is reduced and other features like edge sharpness and pattern recognition...

Optical technologies form the key foundations for transport networks used by all major telecommunication carriers. Those networks are made up of equipment supplied by different manufacturers, and utilize different optical switching and transmission technologies. These give rise to distinct islands or "domains" of network nodes of different capabilities. Further, administrative segmentation of n...

Mobile Phone has been widely used in the world and adopted in different application areas involved with SMS has been evolved for downloading logo, ring-tones, advertisement, security notes, and location based system. This paper describe a service that further extends the functionality of SMS, a prototype named as “SMS Credit” is developed that allows customers to perform electronic payment usin...

Future user controlled development of telecommunication services combined with powerful terminal equipment results in many heterogenous services running in a peer-to-peer execution environment. Locating a desired service in such an environment is challenging. In this paper a swarm based optimization algorithm is presented which is capable of finding paths of resources in a complex network envir...

Technological innovation in the telecommunications sector is a key contributor to the rapid diffusion of e-business. The steady drive towards semiconductor miniaturisation leads to a continuous decline in the price of telecommunications equipment and increase in performance. Technological change therefore continues to transform the way telecommunications services are provided and used. Telecomm...
