Nowadays, Software Defined Network (SDN) architectures and applications are revolutionizing the way wired networks are built and operate. However, little is known about the potential of this disruptive technology in wireless mobile networks. In fact, SDN is based on a centralized network control principle, while existing mobile network protocols give emphasis on the distribution of network reso...

Bluetooth-enabled devices are everywhere and in everyday use by a large number of mobile phone users. Harnessing this communication channel for a context-aware system has proved to be a useful step forward in providing simple games, fun events and targeted advertising based on the awareness of the user’s location. As part of a wider project the authors have produced a system that allows users t...

Wireless technology is growing at a breath taking pace and is influencing the way people live and interact. A wireless system enables users to go anywhere, still be connected to both voice and data communications and have access to systems with different levels of complexity ranging from voice communications to database retrieval. The satellite based global positioning capability has added anot...

This specification defines a Uniform Resource Name (URN) namespace for the Global System for Mobile Communications Association (GSMA) and a Namespace Specific String (NSS) for the International Mobile station Equipment Identity (IMEI), as well as an associated parameter for the International Mobile station Equipment Identity and Software Version number (IMEISV). The IMEI and IMEISV were introdu...

Today’s fast growing world needs fast communication, either it may be voice or data .This calls for a new technology which is faster than all existing technologies in mobile communication and hence can replace technologies like GPRS .Enhanced Data for Global Evolution (EDGE) is such a technology .EDGE is a member of global system for mobile communications(GSM). In short EDGE is a technology whi...

objective(s) the possible risks of radio-frequency electromagnetic fields (emf) for the living organisms and human body are a growing concern for our society. in this study, we examined the possibility of changes in working memory and hippocampal histological characteristics effects in mice brain following whole body exposure to microwave radiation. materials and methods during gestation period...

In Japan, the total number of mobile-phone and personal handy-phone system (PHS) users reached 111 million as of the end of February 2009 and the penetration rate of the third-generation mobile communications system (IMT-2000) exceeded 88%. These figures testify to the provision of a data communications environment for mobile users. At the same time, the use of data communications via mobile ph...
