摘要

經過 921 大地震的災難後, 由於基地台的毀損或停電, 卻導致整個無線通訊網路的癱瘓, 給我們一些省思, 本篇論文提出的整合性無線通訊網路, 可避免當基地台無法正常運作時, 可運用隨意型無線通訊網路的運作原理, 透過其他行動主機連結到運作正常的基地台來持續進行無線通訊, 甚至無法連結到運作正常的基地台時, 仍可以隨意型無線通訊網路來獨立運作, 不會因為單一基地台的毀損而導致無線通訊無法運作, 可提供更穩定且不受外界環境影響的無線通訊網路。
藉由全球衛星定位系統(Global Position System, GPS)的輔助, 整合性無線通訊網路可以分割成數個互相不重疊的子無線區域網路。在階層式繞送表繞送法則的運用下, 行動主機可以自動切換運作於有基礎架構的無線通訊網路及隨意型的無線通訊網路, 使得無線通訊更暢行無阻。

During the period of “921” earthquake, power failure and the destruction of base station make the entire cellular network functions improperly. The suffering reminds us that some important issue must be taken care of. Integrated wireless communication networks, presented in this paper, can provide a solution. The application of ad hoc wireless routing protocol to cellular networks make a mobile host roam between normal mode and ad hoc mode freely. Therefore, the wireless communication can still be available by connecting mobile hosts to the normal base station when a base station is failed. Even if mobile hosts can not connect to the normal base station, mobile hosts can still operate in the ad hoc wireless network independently. Integrated wireless networks provide a reliable and robust wireless communication environment.
With the aid of Global Position System, short for GPS, integrated wireless networks can be partitioned into definite number of non-overlap wireless local networks. By using hierarchical link state routing protocol, mobile hosts can auto-switch between normal mode and ad hoc mode. The application of integrated wireless networks makes wireless communication unimpeded.
