The Global System for Mobile Communications (GSM) is widely recognized as the modern digital mobile network architecture. Increasing market demands point toward the relevancy of security-related issues in communications. The security requirements of mobile communications for the mobile users include: (1) the authentication of the mobile user and Visitor Location Register/Home Location Register;...

Background:As the use of mobile phones is increasing, public concern about the harmful effects of radiation emitted by these devices is also growing. In addition, protection questions and biological effects are among growing concerns which have remained largely unanswered. Stem cells are useful models to assess the effects of radiofrequency electromagnetic fields (RF-EMF) on other cell lines. S...

Many security mechanisms for mobile communications have been introduced in the literature. Among these mechanisms, a simple authentication technique for use in the global mobility network (GLOMONET) is proposed. Specifically, the wireless medium introduces new opportunities for eavesdropping of wireless data communications. Anyone with the appropriate wireless receiver can eavesdrop and this ki...

<span>This paper proposes a cheap solution to be starting point for building smart electrical power billing systems. Electrical has many challenges issues in Iraq, one of these and the most important is Billing system. The meter uses an Arduino Uno as core controlling sensed data transmits it unit services. system constructed with two parts: transmitting measures current, voltage, factor ...

During the last decade several standards for Mobile telecommunications have been developed. The best known is without any doubt the Global Standard for Mobile Communications (GSM) which is operational in many countries, both within and outside Europe. It is now the most successful standard for mobile communications. Also the Digital Enhanced Cordless Telecommunications (DECT) was successfully i...
