摘要
無線通訊技術的發展和應用，在最近幾年當中，可說是逢勃發展且日新月異，而個人通訊服務系統在未來也將變成一種趨勢。然而在目前的個人通訊服務系統的架構中，有時後也會因為機器負載過重、自然因素或是某些人為操作因素…等等的突發事件，終究還是會造成基地台故障或損壞，造成機器停擺，因而中斷使用者之間的通訊。 為此，本論文提出了一個解決的方法，在基地台因外力因素而停擺的同時，由行動主機內部向外做廣播的動作，採用本論文所提出的搜尋演算法，再加上隨意型的無線通訊網路的特性，企圖來解決因基地台的損壞問題而引發的不可預期的後果，並且儘量的讓使用者能夠在任何時間任何地點，均可達到自由通訊的目的。

In recent year, wireless communication technology develops quickly and personal communication systems will be a trend in the future. However, in the framework of the personal communication systems, sometimes some unexpected reasons, such as heavy machine load、 natural reason or personal operation reason at so on. Eventually base stations may be failure or broken, letting machine stop and break communication between users. Therefore, the paper proposes a solution for these problems. Because of some factors like power failure, failed base station etc., base stations will not work, and mobile hosts will broadcast to search for an available mobile host at the same time. If we adopt the search algorithm by the manner of the paper and combine the characteristic of the ad hoc wireless communication network, some emergencies issue could be solved and let users achieve the goal of free communication as far as possible in any time and any position if base stations failure.
