Ad hoc networks might be a disruptive technology in the mobile telecommunication industry. They are based on technologies like 802.11x and Bluetooth and range from wide area solutions to Personal Area Networks. Although they may not substitute current infrastructure in the near future they may threaten the dominant position of mobile operators enabling other players within the mobile value syst...

Mobile Software Agents are widely used in telecommunication networks and the Internet, however their application to embedded systems such as Wireless Sensor Networks is immature. We present a novel middleware supporting and enabling Mobile Agent applications to run natively, without any translation layer, on Wireless Sensor Networks. We establish that Mobile Agent systems are beneficial for a w...

In this paper, we propose a new type of parallel genetic algorithm model for multi objective optimization problems. That is called a ”Master-Slave model with Local Cultivation model (MSLC)”. To clarify the characteristics and effectiveness of this model, the proposed model and the various EAs are applied to solve an antenna arrangement problem of mobile telecommunication. Thorough this problem,...

Even though the radio was invented more than 100 years ago, it has not been until 10-15 years ago that widespread use of wireless communications has begun. While before then it was mainly used by police and military, now the capability of communicating without being constrained to a fixed physical location is within everyone’s reach. The booming industry which has been growing at such an astoun...

Current global telecommunication landscape is undergoing a paradigm change in terms of technologies and usage. Global System for Mobile (GSM) communications has emerged as the preferred technology followed by the fast growing Code Division Multiple Access (COMA) technology. Developed countries (without the transition countries) lead the world in number of landline and cellular connections, foll...

Introduction Voice over IP (VoIP) has been characterised as the largest change to the telecommunication industry since the introduction of the Global System for Mobile Communication (GSM) 10 years ago. This statement is partly wrong. VoIP could be deployed as an alternative way to provide telephony with very little impact on the user experience. However, VoIP is an element of the transition fro...

T he advent of mobile telecommunication systems has brought the term user mobility to next-generation telecommunication network research and design. User mobility implies two things: terminal mobility—the ability of the network to locate a mobile terminal—and personal mobility— the ability of users to access defined services from any terminal in the network, while maintaining their personal env...

Multicast transmission is one of the major goals for Universal Mobile Telecommunication System (UMTS) that motivated the 3 Generation Partnership Project (3GPP) to launch the Multimedia Broadcast/Multicast Service (MBMS) framework. MBMS constitutes a significant step towards the so-called Mobile Broadband, since it allows the efficient utilization of network and radio resources. One of most imp...
