The provision of adaptive content to mobile wireless devices has increasingly become very pertinent. Mobile smart phones and other wireless device usage is increasing daily with ground breaking technological developments – in design, style, content and micro-chips performance. Transmission of data in such environments requires absolute security to protect the individual and content. Any interfe...

I. ABSTRACT The last decade of the 20 century has been witness to remarkable technological developments in the area of wireless communication technologies. Following the commercial deployment – and subsequent worldwide success – of 2 generation mobile telecommunication systems, such as GSM, standardization bodies, industry partners and regulatory fora from around the globe joined forces in prod...

Railway wireless communication has become an indispensable part to provide the reliability and safety of the railway operation as well as the improved railway services. In addition, advanced mobile communication technologies have triggered new railway customer services. Thanks to many benefits of the 4-generation mobile communication technology, long-term evolution (LTE), this technology is one...

The user authentication process is an important task in mobile networks. With the development of new standard Universal Mobile Telecommunication System (UMTS), the security weaknesses of previous standards are removed. However one security weakness has been found by researchers in UMTS, which is the sending of user's International Mobile Subscriber Identity (IMSI) in plain text over the air int...

This paper presents a study of base station system configurations for the Universal Mobile Telecommunication System (UMTS). The base station system (BSS), being the interface between the mobile terminal and fixed network, should be capable of handling a huge amount of traffic, mobility, and a high signaling load which is expected in the UMTS. Several functions that should be supported by BSS ar...

Mobile Ad-hoc Network is a self configurable routing protocol. Nodes in MANET can shift freely from one place to another place and each node in MANET can take action as a transmitter, receiver and router. WiMAX is a telecommunication technology standard which provides fixed and mobile Internet access. Access Server Network (ASN) in WiMAX provides the layer 2 connectivity to the user equipments....
