Wireless security is becoming increasingly important as wireless applications and systems are widely adopted. Numerous organizations have already installed or are busy in installing “wireless local area networks” (WLANs). These networks, based on the IEEE 802.11 standard, are very easy to deploy and inexpensive. Wi-Fi allows LANs to be deployed without cabling for client devices, typically redu...

In recent years, wireless sensor networks have been used in a wide range of indoor localization-based applications. Although promising, the existing works are dependent on large number anchor nodes to achieve localization, which brings issues increasing cost and additional maintenance. Inspired by cross-technology communication, an emerging technique that enables direct communication among hete...

Recently, there has been great interest in the community over heterogeneous wireless networks in order to support services with high quality. The integration of Wimax and Wi-Fi technologies in communication systems such as Voice ,FTP,Video conducted heterogeneous system and reveal that the proposed network selection technique can effectively decide the optimum network through making trade-offs ...

OBJECTIVE In today's world, 2.45-GHz radio-frequency radiation (RFR) from industrial, scientific, medical, military and domestic applications is the main part of indoor-outdoor electromagnetic field exposure. Long-term effects of 2.45-GHz Wi-Fi radiation on male reproductive system was not known completely. Therefore, this study aimed to investigate the major cause of male infertility during sh...

INTRODUCTION: The most flexible and reliable technological system is Wi-Fi, which made possible by a wireless connection that transmits data using radio frequencies. Wi-Fi networks, however, encounter numerous issues related to power supply, availability, efficiency, security as result of the various access points. While relational waves describe medical device, radios produce are very dangerou...

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

Objective(s): The placenta provides nutrients and oxygen to embryo and removes waste products from embryo’s blood. As far as we know, the effects of exposure to Wi-Fi (2.4 GHz) signals on placenta have not been evaluated. Hence, we examined the effect of prenatal exposure to Wi-Fi signals on anti-oxidant capacity, expressions of CDKNA1, and GADD45a as well as apoptosis...

Today, it is common for a household to install a wireless Access Point (AP) for its home network. However, the increasing number of APs and wireless devices inevitably results in more contention and interference, which causes unsatisfactory Wi-Fi network performance. Furthermore, isolating the root causes of poor performance is nontrivial because the problem may be caused by collision with pack...
