On IEEE 802.11: Wireless LAN Technology

Network technologies are traditionally based on wireline solutions. But the introduction of the IEEE 802.11 standards have made a huge impact on the market such that laptops, PCs, printers, cellphones, and VoIP phones, MP3 players in our homes, in offices and even in public areas have incorporated the wireless LAN technology. Wireless broadband technologies nowadays provide unlimited broadband ...

IEEE 802.11 Wireless LAN

In this case study we consider model-checking of some properties for IEEE 802.11 Wireless LAN [1]. Since stations in wireless LANs are not able to listen to their own transmission they cannot employ Carrier Sense Multiple Access with Collision Detection (CSMA/CD) as already investigated in one of our other case studies. Hence, other techniques need to be used to handle collisions. The IEEE 802....

Qos Support for Ieee 802.11 Wireless Lan∗

In today’s Internet, the emerging widespread use of real-time voice, audio, and video applications makes Quality of service (QoS) a key problem. Meanwhile, the Internet is getting heterogeneous due to the explosive evolution of wireless networks. QoS support in wireless networks is more challenging than in the wired networks since bandwidth is scarce, latency and bit error rate are high and cha...

Optimization of IEEE 802.11 Multirate Wireless LAN

IEEE 802.11 standards support multiple data transmission rates with dynamic rate switching capability to improve the performance. With multirate enhancement, data transmission from wireless LAN (WLAN) stations can take place at various rates according to channel conditions. This paper investigates the problem of optimizing aggregate saturation throughput of a multirate WLAN. Analytical expressi...
