Development of Self-organizing High-Speed Wireless LAN

随着能够实现高速传输的光纤的发展，有线通信网络正在向传输多媒体业务的方向发展。在这种趋势下，无线局域网被认为可以处理多媒体业务。本研究旨在开发融合有线高速网络和无线局域网的下一代局域网，并取得了以下成果。提出了一种对局域网拓扑变化具有灵活性的自组织方法，并通过计算机仿真对该方法的性能进行了评估，仿真结果表明了该方法的有效性。提出了一种并行传输方法，即使在无线信道中也能实现高速传输。在该方法中，ATM信元以流水线方式在多个无线信道中传输。提出了利用捕获效应的无线信道多址接入方法。对于将作为下一代无线局域网骨干网的ATM广域网和ATM局域网，考虑了多媒体业务和组播业务的业务控制，并提出了新的方法。

With development of optical fiber which enables high speed transmission, wired communication network are going to transmit multimedia traffic. With this trend, wireless LAN has been thought to treat multimedia traffic. This study were aiming at development a next generation LAN which integrates wired high speed network and wireless LAN and obtained the following results.1. Self-organizing method was porposed, which has flexibility for topological change of LAN.Performance of the method was evaluated with computer simulation and the simulation results show its efficiency.2. Parallel transmission method was proposed, which enables high speed transmission even in wireless channel. In this method, ATM cells are transmitted in multiple wireless channels in a pipeline fashion.3. Multiple access methods for wireless channel were proposed, which makes use of capture effect.4. For ATM WAN and ATM LAN,which will be used for backbone networks of a next generation wireless LAN,traffic control for multimedia traffic and multicast traffic are considered and new methods for them are proposed.
