[[alternative]]Modeling and Analyzing Ad-hoc Network Routing Protocols Using an Emulator

[[abstract]]學者進行隨意式網路 (Ad-hoc Network)路由協定之研究與效能評估時，多以模擬器 (Simulator)來建置實驗環境，透過模擬器產生虛擬資料流量以測試不同路由協定之間的效能差異，然而藉由虛擬流量所得的結果較缺乏真實性，所以部份學者預先建置實際的隨意式網路環境，然後再進行實驗以求得真實世界之實驗數據，但是所需要建置的硬體成本與實驗環境佈置困難度皆較高。本研究藉由QualNet建置模擬與仿真的實驗平台，套用三個路由協定至此實驗環境中，發現下列結果，(1)兩實驗平台所得實驗數據雖然有所差異，但其代表意函卻是相輔相成，仍具一定的可信度；(2)經由仿真器平台所得影像品質分析發現，資料傳送時，若限制所經過的Hop數目，目的端可獲得主觀認定的清晰影像畫質，而這是一般模擬器所無法發現的現象。[[abstract]]At present, a lot of scholars are carrying the study on Ad-hoc network routing protocols. There are some scholars implement a real Ad-hoc systems to evaluate its performance. However the both cost and time of implementing real system is expensive. Therefore, some scholars construct experiment simulations of Ad-hoc routing protocols; however, the simulation result lacks the authenticity.This thesis applies three route protocols mechanically and comes here in the experiment environment with the construction simulation and emulation of QualNet experiment platform, find that is arranging the result, (1)Though two experiment platform income experimental data are different to some extent, but it is to complement each other, still has certain credibility; (2)Analyze and find via the image quality of the emulation platform, data transmission through limit hop count, destination node can subjectively consider that obtain clear image quality, this is a phenomenon that a general simulator can't be found
