The IEEE 802.11 wireless LAN (WLAN) is the most widely used standard nowadays for wireless LAN technology. However, the current standard does not provide QoS support required by the wide range of end applications (e.g., multimedia communications). Thus, a large number of enhancements to the standard are being proposed. This paper summarizes some of the most relevant schemes and presents a surve...

The necessary information content and recommendations for an organization for Software Design Descriptions (SDDs) are described. An SDD is a representation of a software system that is used as a medium for communicating software design information. This recommended practice is applicable to paper documents, automated databases, design description languages, or other means of description. No par...

ABSTRACT-Wireless Local Area Network (WLAN) that uses the IEEE 802.11 standard and WiMAX (Worldwide Interoperability for Microwave Access) that uses the IEEE 802.16 standard are networks that we are want to explore. description of the existing wireless technology Wi-Fi and WiMAX, and try to compare Wi-Fi (IEEE 802.11) and WiMAX (IEEE 802.16). Wireless Local Area Network (WLAN) uses of IEEE 802....

Wireless Local Area Networks (WLANs) are one of the fastest growing wireless access technologies. The IEEE 802.11 Standard doesn’t support any QoS mechanisms. IEEE 802.11 MAC layer supports two basic access mechanisms, DCF (Distributed Coordination Function) and PCF (Point Coordination Function). The EDCA mechanism of the IEEE 802.11e standard provides QoS support through service differentiatio...

Wireless building automation is one of the emerging technologies nowadays. Currently, InfraRed, Radio Frequency, Wi-Fi and Bluetooth are been used for this purpose but they have numerous disadvantages associated with them such as high complexity and higher power consumption. But, certain wireless monitoring and control applications for building automation demand lower power consumption, less co...
