摘要： Wireless stations (108-1-108-N) contending for exclusive access for a predetermined period of time (S232) to transmit on a communication medium (112) are regulated by a common external controller (104) using a single timing parameter (S204). Attempts at transmission access are preceded by respective delays that are expired simultaneously and at a common rate by the stations at times when the stations sense the medium to be idle (S224). The delays are pseudo-randomly selected to avoid collisions among stations in their respective access attempts (S208). Default, initial values of the respective delays (S204) applied to the stations, when multiplied by the respective expected number of transmission attempts by the stations over the long term over periods of time when no transmission attempt is unsuccessful, yield respective products equal to a constant value common to all stations (S312). The default values therefore serve as a knob by which the controller regulates air time opportunity.
摘要翻译：在通信介质（112）上进行发送的在预定时间段（S232）中进行专用访问的无线站（108-1-108-N）由公共外部控制器（104）使用单个定时参数来调节（S204 ）。在发送接入的尝试之前是在站感测媒体空闲的时刻（S224）的同时到达的各个延迟以及站的共同速率。延迟是伪随机选择的，以避免各个接入尝试中的站之间的冲突（S208）。默认情况下，应用于站的各个延迟的初始值（S204）当乘以在不发送尝试不成功的时间段内长时间站的相应预期发送次数时，产生等于所有站通用的常数值（S312）。因此，默认值用作控制器调节空气时间机会的旋钮。

摘要： The application describes a method to merge two wireless networks in which each terminal gets a beacon slot within the beacon period. In order to merge two networks, the beacon slots have to be time-coordinated such that the beacon slots of the first network are completed before the beacon slots of the second network begin. The method includes transmitting a beacon frame having a beacon period switch information element which instructs the neighboring terminals in the first network of the need to merge, provides clock synchronization information; provides the time of the merge; and informs the neighboring terminals which beacon slot to occupy in the beacon period of the merged network. In order to deal with hidden terminals, the information needs to be forwarded terminal-to-terminal within each network.

摘要： A clock synchronization method and apparatus is disclosed for use in a communication system including a plurality of wireless nodes communicatively coupled via a wireless network, each of the plurality of wireless nodes having a local time base, and one of the plurality of wireless nodes being designated as a master node having a master time base which serves as a master clock against which the local time bases are synchronized. The clock synchronization method includes the steps of periodically transmitting synchronization frames to the plurality of non-master nodes so as to adjust the slave clocks associated with the respective non-master nodes. The synchronization frames are distributed from the master node at near-periodic intervals and includes a cycle time value that corresponds to the end of the previously transmitted synchronization frame. The slave clocks (i.e., non-master nodes) receiving the synchronization frame determine the cycle time value at the point of reception of the synchronization frame and adjusts their clocks by calculating a difference value between the received cycle time and a previously saved local cycle time value.
