As cellular data services and applications are being widely deployed, they become attractive targets for attackers, who could exploit unique vulnerabilities in cellular networks, mobile devices, and the interaction between cellular data networks and the Internet. Furthermore, mobile devices, often times considered to be part of the cellular network’s trusted computing base (TCB), are becoming m...

Mobile cellular telephone subscriptions are subscriptions to a public mobile telephone service using cellular technology, which provide access to the public switched telephone network [1]. Nowadays, mobile phone handhelds are everywhere and are used for various applications. Convergence of media provides a great opportunity for mobile users. Yet, there has been a growing rate of challenges acco...

The ever growing data traffic generated by users in cellular networks is becoming more challenging and straining for cellular operators. Thus, developing efficient mechanisms that enable cellular operators to offload data traffic from their networks in a cost-effective manner is essential. To this end, we propose a generic framework (MFW) that exploits femtocells and WiFi networks. The framewor...

The memory constrained nature of mobile devices, such as smartphones, limits the amount of data that can be stored locally. As a result, mobile devices often rely on cellular connections to retrieve application data. Environmental factors, however, can partially or completely restrict cellular connectivity. Autonomic distributed caching mechanisms can be used to allow mobile device networks to ...

Introduction: Radiation from cell phones has been associated with an increased risk of cancer. The literature has reported evidence of certain biological effects resulting from exposure to various wavelengths, doses, and intensities of radiofrequency radiation. The present study aimed to evaluate the possible adverse effects of radiation from a GSM mobile phone operating at 900 MHz on human mel...

Determination of mobile localization with time of arrival (TOA) signal is a requirement in cellular mobile communication. In some of the previous methods, localization with non-line-of-sight (NLOS) paths can lead to large position error. Also for simplicity, in most simulations suppose non stationary actual environments as stationary. This paper proposes (residual test + recursive least square)...
