该策略将时间分为周期性信标区，包括信道协商窗口和数据窗口。

According to this scheme, time is divided into periodical beacons comprising of a channel-negotiation window and a data window.

针对移动无线传感器网络中周期性信标交换引起的通信暂盲现象，提出一种自适应信标交换算法。

To address the phenomenon of temporary communication blindness resulted from fixed period beacon exchange in mobile wireless sensor networks, an adaptive beacon exchange algorithm is proposed.

对这三种方案的补偿有效性和连续性分别进行了理论研究，结果表明：补偿后，三种方案均能使偏振耦合分光系统对返回信标光的接收效率达到90％以上；

The validity and continuity of these three solutions is numerically simulated, and the results show that all of them can make the receiving efficiency be better than 90% after compensation.
