access contention

In this paper, to resolve the problem of channel access in the application of short distance wireless communication system, two mechanisms are discussed which are roll-call access and contention access.

针对短距离无线通信系统在现实应用中的信道接入问题，论述了两种信道接入机制&轮询方式和竞争方式。

In 802.11e, enhanced Distributed coordinate function ( EDCF) allows wireless station to access the channel by contention.

这个协议所提出的基于竞争接入信道的机制称为增强型分布式协调方式（EDCF）。

Next, the operation and evaluation of a new traffic scheduling algorithm for contention-free medium access referred to adaptive transmission opportunity ( ATX) are presented.

所以，本文提出了一种新的与自适应传输机会相关的针对无竞争介质接入过程的业务调度控制算法并对其性能进行了评估。

A New Kind of Medium Access Control Protocol with Contention

一种新的竞争型介质访问控制协议

To reduce database contention independent of making disk configuration changes, try approaches that may reduce database access contention or improve file access time.

如果希望减少数据库争用，但是不愿意修改磁盘配置，那么应该尝试减少数据库访问争用或改进文件访问时间的措施。

There are mainly two kinds of medium access functions, contention access function and center controlled scheduling function.

MAC层接入方式主要有竞争接入和中央控制的调度接入两种。
