This paper proposes an efficient network architecture to improve energy consumption in Wireless Sensor Networks (WSN). The proposed architecture uses a mobile data collector to a partitioned network. The mobile data collector moves to center of each logical partition after each decision period. The mobile data collector must declare its new location by packet broadcasting to all sensor node...

The production, distribution, and consumption of information are the most important development indices of any nation. Plenty of opportunities were created by e-learning which have overall paved the grounds for and enriched the presentation of learning materials through advanced audiovisual educational facilities. Such learning environments are by and large flexible and provide more appropriate...

Despite the widespread use of mobail phones in Iranian students, psychological and behavioral effects of addiction to it and its consequences have not been investigated yet. The aim of this study was to determine the relationship between cell phone dependency with psychological disorders and academic burnout among nursing and midwifery students. In this study, 169 students were chosen through s...

Introduction: With the increase in mobile phone usage in public places, the use of mobile phone jammer has also increased therefore, the aim of this study was to evaluate the effects of mobile phone jammer on the level of anxiety in mice. Methods: Forty male and 40 female naive mice (25-30 g) were randomly divided into four groups (control, 900 MHz, 1800 MHz and 900+1800 MHz exposures). Ani...

 In recent years, mobile networks have faced with the increase of traffic demand. By emerging mobile applications and cloud computing, Mobile Cloud Computing (MCC) has been introduced. In this research, we focus on the 4th and 5th generation of mobile networks. Data Centers (DCs) are connected to each other by high-speed links in order to minimize delay and energy consumption. By considering a ...

Introduction: Mobile phones and computers are a reservoir of growth and transmission of microorganisms. This study aimed to evaluate the microbial contamination of computers and mobile phones used by students of an academic dental school, compared to the students of a non-medical school. Methods: Sampling was performed on 44 computers and 45 mobile phones in a dental school (test) and a non-med...
