The paper describes and compares different approaches that can be used to design Network Power Management methods, with the aim of reducing the power consumption of telecommunication networks. The approaches are based on the solution of optimization problems that have, in general, a Mixed Integer NonLinear Programming (MINLP) formulation. Given that the problems are NP-hard, exact methods for f...

In this paper, we defined the dynamic model to treat the problem of evaluation of reliability measures of a telecommunication network. We used two approaches, the first is based on the factoring method when the second is based on discrete events simulation techniques. We give some numerical results on the telecommunication network of Bejaia town.

The energy consumption of telecommunication networks can be reduced using dynamic power management techniques, which allow network performance to be traded off against energy consumption. Such techniques can be applied on devices by means of hardwarespecific local control policies. Distributed power management across heterogeneous hardware requires a standardized representation of the capabilit...

nels in the future. Furthermore, teleservices process more Emerging telecommunication services use, store, or transmit sensitive personal data to form individual network services. We suggest an add-on approach to realize secure telecommunication services which saves the huge investments into existing network infrastructure of the ISDN. This is done by adding trusted runtime environments that co...

Ž . The ATM Asynchronous Transfer Mode network is regarded as effective for a multimedia telecommunication environment that enables high-speed and broadband communication. This paper reports on the system architecture and Ž . design concept of the FETEX-150 ESP Enhanced Switching Platform which has been designed as an ATM switch in a public broadband network. To track the latest ATM standards a...

The paper presents an approach to a combined service and location management for 3rd generation mobile networks in a deregulated, competitive telecommunication market. This approach enables the provision of tailored services which allow users to customise them individually. The resulting user profile is stored in so-called User Agents that act on behalf of their respective users in the fixed ne...

Many military research efforts have concentrated on how to allow war-fighters to take advantage of all available information within the battlefield in a rapid and flexible manner. As a result, the development of the Global Information Grid (GIG) was the key enabler for this process; hence, adding to the development of the mobile networking part of the GIG, the concept of the Mobile Ad hoc Netwo...

There is significant signaling message activity in Universal Mobile Telecommunication Systems (UMTS) among Core Network (CN) elements for the mobility management of UMTS subscribers. The time-overhead introduced with the performance of these signaling operations is a crucial factor that determines the overall performance of UMTS technology and affects greatly the application Quality of Service ...

This paper deals with the architecture, design and implementation of a Management Information Tree(MIT) supporting efficient Managed Object(MO) selection. We present the architecture and mechanism of the MIT in detail and also show how the proposed architecture is implemented in a Telecommunication Management Network(TMN) platform. In addition, we present a new mechanism decreasing MO selection...

In this study, an Internet Protocol(IP)-based integrated network management system(INMS) that can be managed on site and remotely was designed. To derive the requirements for an offshore plant INMS, the status of the offshore plant-related industries was analyzed, and the structure and functions of the system were designed by referring to the actual ship-owner specifications and shipbuilding ya...
