In recent years, the rapid progress of hardware technology has enabled people to use mobile terminals away from the ofice or home with the use of cellular phones. However there are not a little remaining issues which are narrow bandwidth of wireless communications, the limited battery duration of mobile terminals, and others. This paper proposes a common memory management mechanism for mobile t...

Mobility gains more and more importance from a technological as well as social perspective. On the one hand, mobility is required from the personal and professional environment in order to keep pace with the developments in a global world. On the other hand, the existence of wireless networks and the success of cell-phones enable a wide usage of mobile communication infrastructure. While mobile...

Mobile and wireless technologies have evolved beyond recognition since the first radio signals were transmitted by pioneers including Nikola Tesla and Guglielmo Marconi in the late nineteenth century. Radio waves have been used since then as a basis for telephony, audio and video broadcast, and navigation and radar systems. More recently, the advent of mobile phones and similar devices has tran...

In an era of information technology, mobile phones are more and more widely used worldwide, not only for basic communications, but also as a tool to deal with personal affairs and process information acquired anywhere at any time. It is reported that there are more than 4 billion cell phone users over the world and this number still continues to grow as predicted that by 2015 more than 86% of t...

A large number of techniques for location estimation relying on the existing wireless radio infrastructures have been proposed in the last few years. Solutions relying on the use of cellular networks can be used almost everywhere, but tend to have low precision. In this paper, we propose the use of information sharing among nearby mobile phones for improving accuracy of cellular-based location....

Mobile ad hoc network is a collection of wireless mobile nodes, such devices as PDAs, mobile phones, laptops etc. that are connected over a wireless medium. There is no pre-existing communication infrastructure (no access points, no base stations) and the nodes can freely move and self-organize into a network topology. Hence, balancing the load in a MANET is important because the nodes in MANET...
