Wireless networking is becoming anytime and everywhere, but it is still hard to communicate between computing objects. If a user can easily make a connection between the user’s terminal and surrounding computers, the user can temporarily utilize the computers’ resources, including a display or a camera. There are many projects tackling this problem, but the user operation issue still remained u...

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...

Personal Communication Network (PCN) is an emerging wireless network that promises many new services for the telecommunication industry. The high speed backbone network (ATM or WDM) is one possible approach to provide broadband wireless transmission with PCN's using the ATM switching networks for interconnection of PCN cells. The wireless ATM backbone network design problem is that of allocatin...

Telecommunication companies have received a great deal of research attention, which have many advantages such as low cost, higher qualification, simple installation and maintenance, and high reliability. However, the using of technical maintenance approaches in Telecommunication companies could improve system reliability and users' satisfaction from Asymmetric digital subscriber line (ADSL) ser...

In this study, we examine Information and Communication Technology and Development (ICT4D) technology interventions that have been developed over the last decade. The purpose is to provide a snapshot of the trends that have characterized ICT4D technology interventions from the period starting 1995 to 2010. This paper presents seven variables to categorize projects over this period namely: resea...

The paper presents the authors’ experience in designing and implementing secure smart card and agent-based telecommunication services supporting user mobility and service personalization. The work described here has been performed as part of the EU ACTS SCARAB project and is based on a service architecture that has been defined by the SCARAB partners. User mobility is achieved both by using sma...

This paper deals with the design and realization of an echo-canceller board for a VME bus. The work has been carried out by integrating the abilities and the competences of some academic and industriai research groups within the framework of Subproject 3.1 of the ltalian National Research Council «TelecommuniCation Project». The board implements an efficient algorithm for the cancellation of ac...

In this paper, we are concerned with the performance evaluation of code allocation algorithms in Universal Mobile Telecommunication System (UMTS) networks. UMTS networks will offer multiple services (voice, data, video, etc.) with different quality-of-service (QoS) requirements to mobile users. In this paper, we evaluate the performance of different code (rate) allocation algorithms on the UMTS...

This paper describes an Intelligent Network (IN) concept in mobile communications and shows the implementation of personal mobility in mobile communication networks. Even though the current Wireless Intelligent Network (WIN) protocol does not accommodate Universal Personal Telecommunication (UPT) service, we design UPT service in the WIN. We assume that service pro le and location information o...
