Low power IoT communication signals (e.g., Bluetooth and ZigBee) may seriously suffer from the presence of high-power co-channel interference like wireless local area network (WLAN) signal. They effectively avoid WLAN by exploiting dynamic characteristics traffic. Representing arrival/departure users using an M/M/m/m queueing structure, characterization large-scale dynamics channel occupancy is...

In Wireless Local Area Networks (WLAN), beacon, probe request and response messages are unprotected, so the information is visible to sniffers. Probe requests can be sent by anyone with a legitimate Media Access Control (MAC) address, as association to the network is not required at this stage. Legitimate MAC addresses can be easily spoofed to bypass Access Point (AP) access lists. Attackers ta...

Wireless Local Area Network (WLAN) offloading is an important approach to address the data traffic challenge faced by Long Term Evolution (LTE) network. Legacy offloading solutions based on the core network suffer from the limitations of load unbalance and user experience degradation. To solve this problem, 3GPP has recently proposed a radio access network (RAN) assisted WLAN offloading scheme....

Introduced location technology based on wireless LAN (Local Area Network). Analyzed three kinds of commonly used localization methods at present, and pointed out their advantages and disadvantages. Combining triangle position with RSSI (Received Signal Strength Indication), developed the study of location technology base on WiFi (Wireless Fidelity) technology in this paper, and prototype experi...

The integration of wireless local area network (WLAN) hotspot and the 3G cellular networks is imminently the future mode of public access networks. One of the key elements for the successful integration is vertical handoff between the two heterogeneous networks. Service disruption may occur during the vertical handoff because of the IP layer handoff activities, such as registration, binding upd...

Wireless access networks have become common in public facilities such as airports, hotels, cafés and restaurants. By providing wireless local area network (WLAN) access facility owners can attract new customers and create added-value for their core services. These facilities are often called hotspots. Hotspot owner can provide an open network access free of charge and thus create added-value fo...

Wireless local area networks (WLANs) have appeared in many venues, including academic and corporate campuses, residences, and wireless ‘‘hotspots.’’ It becomes increasingly important to understand how these networks are used, as they continue to appear in more numerous and varied environments. Measuring and collecting data from production WLANs in a usage study is one way of fulfilling this nee...

Enhanced distributed channel access (EDCA) is used for transmitting good quality of service of multimedia traffic in wireless local area network (WLAN). Applications like Constant bit rate (CBR), file transfer protocol (FTP) and voice over internet protocol (VoIP) are used in wireless LAN network. Audio data is assign as high priority (AC_VO) and other such as CBR & FTP type of data are assigne...

The selection of security schemes against Wormhole Attack (WHA) in next generation heterogeneous networks is based on major factors: authentication, confidentiality, and integrity and data availability. The effect of this active threat on Quality of Service (QoS) of the Integrated Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) Ad Hoc network can be mini...
