一种无线ATM网的改进型MAC协议

An Improved MAC Protocol for Wireless ATM Networks

在分布式请求更新多址（ＤＱＲＵＭＡ）和分布式排队到达请求多址（ＤＱＡＲＭＡ）协议基础上，提出一种适合多码、多载波ＣＤＭＡ传输的改进型（Ｉｍ ｐｒｏｖｅｄ）分布式排队请求更新多址（ＩＤＱＲＵＭＡ）协议，并对该协议的性能进行分析和仿真。研究表明对于种类多且变换快的业务情况，ＩＤＱＲＵＭＡ协议性能比ＤＱＲＵＭＡ好，在业务种类少或单一的情况下。

After analyzing DQRUMA and DQARMA protocols, an IDQRUMA MAC protocol was proposed. IDQRUMA was quite applicable in multi code and multi carrier parallel CDMA transmission schemes. The throughput and delay performances of IDQRUMA protocol were calculated and simulated. For multiple and quick changeable services, performance of IDQRUMA is better than that of DQRUMA, and for few or single service, IDQRUMA and DQRUMA have similar performances.
