在MANET（Mobile Ad-Hoc Network）環境下，由於是一個沒有基地台的機制，所有的Mobile Host在這個網路環境中，有的時候要當Source，也有的時候就變成Destination，更有可能是充當幫忙其他Mobile Host傳送資料的路由器（Router），在這種情形下，如何找到一條正確的路徑，將一筆資料由Source送出，經過中間的一連串的Routers，最後順利到達正確的Destination，就是Routing Protocol的問題。
但是，一個完整的Routing Protocol，並不是只有包含找出路徑、資料傳輸等兩項工作而已，尚須包含路徑建立後的維護問題，本篇文章的重點是在於如何在一個運作多時的網路環境中，使其所有Mobile Host的Routing Table中的繞徑資訊，皆處於最適合且最新的狀態，如此才能有效的提昇資料傳輸的效率及品質問題。
在本篇文章中的實驗模型，我們將需要作最佳化的情況分為兩種：主動模式與被動模式。主動模式可以讓一個擁有較佳路徑的Mobile Host通知其他正在傳送資料的Mobile Hosts’ Sequence更改其原來Routing Table中的舊路徑，而被動模式則是由一正在傳輸資料的Mobile Hosts’ Sequence，在知道其他更好的傳輸路徑時，能立刻變更其本身Routing Table中的舊有路徑，以便達成路徑最佳化的目標。
本篇文章的重點在於實驗出來的結果，而結果也可清楚的證明路徑最佳化，確實可以增加傳輸的速率，減少傳輸的時間，傳輸品質也就會相對的提昇，這在無線網路不穩定的環境中是非常重要的。
