- On Improving Voice Capacity in 802.11 Infrastructure Networks
- In recent years, 802.11 wireless LANs have become pervasive. While providing wire-free connectivity at low cost, it is widely recognized that the 802.11 MAC layer requires greater flexibility and the new 802.11e standard consequently allows tuning of MAC parameters that have previously been constant. Although the 802.11e standard provides adjustable...

- Jigsaw: Solving the Puzzle of Enterprise 802.11 Analysis
- The combination of unlicensed spectrum, cheap wireless interfaces and the inherent convenience of untethered computing have made 802.11-based networks ubiquitous in the enterprise. Modern universities, corporate campuses and government offices routinely deploy scores of access points to blanket their sites with wireless Internet access. However, while the fine-grained behavior of...

- Introduction to IEEE 802.11
- In 1997 the IEEE adopted IEEE Std. 802.11-1997, the first wireless LAN WLAN standard. This standard defines the media access control MAC and physical PHY layers for a LAN with wireless connectivity. It addresses local area networking where the connected devices communicate over the air to other devices that are...

- Distributed Cognitive Coexistence of 802.15.4 With 802.11
- Thanks to recent advances in wireless technology, a broad range of standards are currently emerging. Interoperability and coexistence between these heterogeneous networks are becoming key issues, which require new adaptation strategies to avoid harmful interference. This paper focuses on the coexistence of 802.11 Wireless LAN and 802.15.4 sensor networks in...

- Performance Issues With IEEE 802.11 in Ad Hoc Networking
- Although 802.11 was initially designed for infrastructure-based networks, the Distributed Coordination Function DCF it provides allows mobiles to access the radio medium without the need of a base station. Thus, studies in wireless multi-hop networks, also called ad hoc networks often rely on the use of the IEEE 802.11 standard...
