IEEE 802.11 is a relatively new standard for communication in a wireless LAN. Its need arose from the many differences between traditional wired and wireless LANs and the increased need for interoperability among different vendors. To date, detailed performance measures for this CSMA/CA protocol

implementation details of IEEE 802.11b Wireless LAN (WLAN) standard on Texas Instruments ’ TMS320C6416 DSP based hardware platform.

on IEEE 802.11g standard in the DCF mode and DCF with TDMA mode which is useful to improve packet collision in traditional wireless networks. In this analysis, improved performance with TDMA base MAC layer is compared without TDMA. We used simulation through using NS-2 Simulator.

Abstract-IEEE 802.11 supports multiple transmission rates. Choosing an IEEE protocol for a network is highly dependent on the traffic load offered by this network as well as running application. In this paper, methods for improving performance of WLANs were investigated. Results shows that better tuning of WLAN PCF parameters for low speed WLAN, can be used to enhance network performance achieving performance compared to high speed WLAN.

��×ØÖ � Ø � The demand for broadband communications is rapidly increasing as small to medium sized businesses and private users add Internet access and remote multimedia to their daily routines. Two major standardization bodies are currently working towards a standard for high speed wireless LANs

This paper describes simulations of the power saving mechanism of the upcoming standard for wireless Local Area Networks IEEE 802.11[1]. They were performed in order to see how typical parameters influence the performance. Simulations were made for a adhoc -network with 8 stations. Figures

Quality of service (QoS) is a key problem in wireless environments where bandwidth is scarce and channel conditions are time varying and sometimes highly loss. Although IEEE 802.11 wireless LAN (WLAN) is the most widely used WLAN standard today, and the upcoming IEEE 802.11e QoS enhancement

Abstract — In this paper, a multihop routing extension to IEEE 802.11 is presented. Multihop extension preserves the traditional single-hop networks where the service infrastructure is constructed by many access points but it also adds the flexibility of ad hoc networks where wireless transfer
