摘要

多媒体网络应用的广泛使用产生了对WLAN系统中QoS支持的需求。由于无线局域网系统的覆盖范围有限，因此多跳无线局域网系统被认为是解决方案之一。然而，在家庭或办公环境中，由于多径传播效应，会降低多跳无线局域网系统的性能。因此，多跳无线局域网系统的QoS保障仍然是一个难点。本文提出了一种多跳无线局域网系统，通过信道估计来选择合适的传输速率，给站提供最优的传输机会，从而保证无线局域网的服务质量。数值仿真结果表明，采用该系统可以在较宽的覆盖范围内保证QoS传输

Proposal of Multi-Hop Wireless LAN System for QOS Guaranteed Transmission

The widespread use of multimedia networking applications has created the need for QoS support in the WLAN systems. The coverage area of WLAN systems is limited, so multi-hop WLAN system is considered to be one of the solutions. However, in home or office environments, due to the multipath propagation effect, the performance of multi-hop WLAN system is degraded. Therefore, QoS guarantee in multi-hop WLAN systems is still difficult. This paper proposes a multi-hop WLAN system for QoS guarantee by using channel estimation to select the appropriate transmission rate and giving optimum transmission opportunity to stations. The numerical simulation results show that by using the proposed system, QoS transmission can be guaranteed over a wide coverage area
