In this thesis, we present a new channel scan method called "random scan" to reduce the delay. The scheme divides the beacon interval into several sections. In each beacon interval, only one section will be scanned and it will take multiple beacon intervals to scan all the section to cover the entire beacon interval.

在本论文我们提出一个减少IEEE 802.11无线网路之漫游所造成服务中断的机制称为随机扫描，此机制将标记间隔切割成数个区段，在每个标记间隔中，只对一个区段进行扫描，剩下的时间可继续正常的传输，以降低服务被中断的时间。

Considering the specialty of pseudo-random vector, a partial scan algorithm for BIST, which unifying the structure analysis and testability analysis, is presented in this paper. Then, the fault simulation experiments on ISCAS89 benchmark circuits by this algorithm is made, and the results, which made by the full scan algorithm and the partial scan algorithm only based on the structure analysis, is compared. The conclusion is achieved: for pseudo-random vector, compared with the full scan circuit and the circuit geted by partial scan algorithm only based on the structure analysis, the circuit geted by our partial scan algorithm can greatly reduce the test time with very close or even greater faults coverage and less area than the full scan.
