It is a very important and to be worthy of research issue which elucidates that how to provide mobile users for roaming among different access technology networks through seamless handoff mechanism. IPv6 will play an important role in the future wireless access networks, each of equipment has its unique IP address. For mobile equipment, IPv6 have mobility support (Mobile IPv6). Therefore, in or...

We consider the problem of e cient multicast support for mobile wireless hosts in TCP/IP networks. We summarize techniques supporting multicasting and mobility, along with their constraints and interactions, and explore architectural alternatives for solutions to the combined problem that remain compatible with the existing architecture. We propose a new mechanism for group management, optimize...

0163-6804/99/$10.00 © 1999 IEEE or many years, the public switched telephone network (PSTN) has provided custom local area signaling service (CLASS) features to residential customers, such as call blocking, caller ID, and call forwarding. However, these services have certain limitations, primarily due to the closed PSTN signaling architecture which does not allow access to network signaling pro...

The fourth generation of mobile networks will truly turn the current mobile phone networks, in to end to end IP based networks, couple this with the arrival of IPv6, every device in the world will have a unique IP address, which will allow full IP based communications from a mobile device, right to the core of the internet, and back out again. If 4G is implemented correctly, it will truly harmo...

results the prevalence of excessive mobile phone use was 36.7% on the students. there was a significant relation between the prevalence of excessive mobile phone use and mental health status in general (p > 0.05), and also somatization (p < 0.05), anxiety and depression specifically (p < 0.05), but no significant relation was found between the excessive mobile phone use and social dysfunction (...

At issue for any organization is the illicit dissemination of sensitive information using file sharing applications within a network, and tracking terrorist cells or criminal organizations that are covertly communicating using Voice over IP (VoIP) applications. This paper presents a field programmable gate array (FPGA)-based embedded software tool designed to process file transfers using the Bi...
