As we are moving toward the next generation all-IP wireless networks, we are facing the integration of non-homogeneous networks, such as wireless wide area networks (WWAN) and wireless local area networks (WLAN). In vertical handoff between WWAN and WLAN, the mobile hosts are required to be able to move freely across different networks while satisfying the quality of service requirements for a ...

The third generation partnership project (3GPP) has addressed the feasibility of interworking and specified the interworking architecture and security architecture for third generation (3G)-wireless local area network (WLAN), it is developing, system architecture evolution (SAE)/ long term evolution (LTE) architecture, for the next generation mobile communication system. To provide a secure 3G-...

The growing demand to provide secure wireless connectivity, especially in hot spot areas such as conference halls and events, motivated the development of Control and Provisioning of Wireless Access Point (CAPWAP) centralized Wireless Local Area Network (WLAN). The centralized WLAN utilizes an Access Controller (AC) to simplify configuration, management, and control of Wireless Termination Poin...

Wireless Local Area Networks (WLAN) do not only provide a means for wireless communication, they can also supply terminal positions to location-aware services and applications. This paper presents a location-aware mobile learning platform and its underlying location service. The system extracts sensor data from a universitywide WLAN infrastructure to determine user locations.

Wireless Local Area Networks (WLAN) has been enthusiastically adopted in our everyday life. However, the current WLAN systems offer very unsatisfactory level of security. Some attacking methods are more dangerous in wireless environment and some additional effort should be used to protect the security of our data in WLAN. So many researchers have been pursuing this goal. This paper presents a b...

The increasing interest in wireless ad-hoc networks built by the portable devices equipped with short-range wireless network interfaces. IEEE 802.15.1 WPAN (Bluetooth) and IEEE 802.11b WLAN (Wi-Fi) are most popular and emerging wireless technologies. These technologies migrates wired system applications into the wireless domain. Applications includes, computing, sensing, and communication. In B...

A filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. This design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. The high isolation between output ports is obtained by combining the half mode substrate integrated wa...

The paper evaluates the security status of Wireless Local Area Networks (WLAN) used by residents and companies in two major cities of the United Arab Emirates (UAE). The goal is to study the security vulnerabilities that lie beneath the usage of WLAN by the public in UAE. Data will be collected from various populated sites and will be analyzed to better understand the wireless security awarenes...

IEEE802.11 wireless networks have become one of the most widely used networks. Due to open nature of wireless medium, hackers and intruders can make utilization of the loopholes of the wireless communication; as a result, there are many security threats associated with Wireless Local Area Network (WLAN). In this paper, we have worked an experimental analysis to study some of the well known atta...

A mobile site level data collection system has been implemented for piling works utilising the IEEE 802.11b wireless protocol. The system, used by dedicated ‘pile managers’ and the workforce, allows for realtime data collection and storage into a site-based server, via a mobile wireless local area network (WLAN). The use of a WLAN allows for easy access and manipulation of timely construction d...
