摘要

远程医疗系统需要一个可接受的网络服务质量和成本。IEEE 802.11无线局域网技术是为了提供可扩展和低成本的网络而发展起来的。然而,在远程医疗应用中,该技术还不能满足服务质量的要求。为了克服这一问题,提出了一种新的跨层无线局域网设计方案。本设计基于IEEE 802.11g标准,在数据链路和物理层进行了修改。该方法已在NS2仿真环境中实现。为实现远程医疗应用的视频数据传输,进行了仿真。仿真结果表明,新的跨层设计在PSNR(峰值信噪比)和延迟值方面都比传统的无线局域网具有更好的网络服务质量。因此,新设计具有应用于远程医疗系统的潜力。

Cross Layer Design of Wireless LAN for Telemedicine Application
Telemedicine system requires an acceptable network quality of service and cost. IEEE 802.11 wireless LAN technology has been developed to provide scalable and low cost network. For telemedicine applications however, the technology does not fulfill the quality of service requirement yet. In order to overcome this problem, a new cross layer design of wireless LAN is proposed.The design is based on IEEE 802.11g standard with modification in datalink and physical layer. This has been implemented in NS2 simulation environment. The simulation has been performed to deliver the video data for telemedicine application. Simulation result shows that the new cross layer design has better network quality of service for PSNR (Peak Signal Noise Ratio) and delay values than the conventional wireless LAN. Thus, the new design has a potential to be used in telemedicine system.
