近年来，出现了各种各样的移动的计算设备，包括便携式设备、掌上型设备和个人数字助理。为这些设备提供足够的网络连接将需要新一代无线LAN技术。在本文中，我们研究的单通道无线局域网正在开发的施乐公司的帕洛阿尔托研究中心的媒体访问协议。我们从Karn [9]首次提出并由Biba [3]改进的MACA媒体访问协议开始，该协议使用RTS-CTS-DATA分组交换和二进制指数回退。使用数据包级的模拟，我们研究各种性能和设计问题，在这样的协议。我们的分析导致了一个新的协议，MACAW，它使用RTS-CTS-DS-DATA-ACK消息交换，并包括一个显着不同的退避算法。
In recent years, a wide variety of mobile computing devices has emerged, including portables, palmtops, and personal digital assistants. Providing adequate network connectivity for these devices will require a new generation of wireless LAN technology. In this paper we study media access protocols for a single channel wireless LAN being developed at Xerox Corporation's Palo Alto Research Center. We start with the MACA media access protocol first proposed by Karn [9] and later refined by Biba [3] which uses an RTS-CTS-DATA packet exchange and binary exponential back-off. Using packet-level simulations, we examine various performance and design issues in such protocols. Our analysis leads to a new protocol, MACAW, which uses an RTS-CTS-DS-DATA-ACK message exchange and includes a significantly different backoff algorithm.
