Mobility assessment on-demand (MAOD) routing protocol for mobile ad hoc networks


In ad hoc wireless networks, the high mobility of hosts is usually a major reason for link failures. The general ‘shortest path’ based routing protocols may not lead to stable routes. In this paper, we propose a mobility assessment on-demand (MAOD) routing protocol to select a stable route in order to enhance system throughput and performance. An error count parameter is used to judge whether a host is highly mobile. The proposed MAOD routing protocol is an on-demand routing protocol similar to dynamic source routing (DSR). The difference between MAOD and DSR is in the path selection method. Because MAOD takes the mobility of hosts into consideration, it will select a more stable and reliable path than DSR. In comparison, DSR only considers whether this route is a shortest path or not. Finally, the system performance is analyzed by using the global mobile simulation (GloMoSim) simulator. We can observe that MAOD routing protocol outperforms DSR routing protocol especially in the high mobility environment. Copyright ( 2004 John Wiley & Sons, Ltd.

KEY WORDS: ad hoc wireless networks; mobility assessment; quality of service (QoS); routing protocols

1. Introduction

Conventional wireless networks require as prerequisites some form of fixed network infrastructure and centralized administration such as cellular based network. However, the conventional wireless networks are infeasible under certain special circumstances, for example, battlefield, disaster (flood, lire, earthquake) recovery, search and rescue, exploration of an unpopulated area etc. Consequently, a new network structure is proposed in wireless environments. It is called the ad hoc wireless networks, also called ‘multi-hop’ wireless networks. Such networks consist of a collection of wireless nodes, all of which may be mobile.


They dynamically create a wireless network among themselves without using any infrastructure or administrative support. Ad hoc networks are self-creating, self-organizing and self-administering. They form an ad hoc wireless network by interactions among their control and administration functions.

    老大,你這篇實在太長了一點,還要再補充? ORZ.這樣翻譯法,我要開始收版稅了。隨建即連網路的 “流動性評估承索”(MAOD)路由通訊協定總結在隨建即連無線網路中, 主機的高流動性通常是鏈接失敗的一個主要原因。基於路由通訊協定的一般 “最短路徑” 可能無法引導穩定路由。在本文裡, 我們提出了 “流動性評估承索”(MAOD)路由通訊協定來選擇一條穩定的路徑,以提高系統的數據處理量和性能表現。(我們)使用錯誤計數參量來判斷主機是否高度流動。所提出的 MAOD 路由通訊協定是一個 “按需路由” 的通訊協定,類似於 “動態來源路” 由(DSR)。MAOD 和 DSR 之間的區別在於路徑的選擇方法。由於 MAOD 考慮到主機的流動性,它將選擇一條比 DSR 更穩定可靠的路徑。相比之下,DSR 只能考慮到這條路徑是否最短路徑。最後,(我們)使用全球流動模擬(GloMoSim)的模擬器來分析系統的性能。我們可以觀察到,MAOD 路由通訊協定在性能上勝過 DSR 路由通訊協定,特別是在高流動性環境裡。版權(2004 年 John Wiley & Sons有限公司。關鍵詞:隨建即連無線網路;流動性評估;服務質量(QoS);路由通訊協定介紹作為先決條件,常規的無線網路要求某種形式上的固定網路基礎設施和集中化管理,譬如手機網路。但是,常規無線網路在某些特別情況下是無法實行的,例如,戰場、災難(洪水、强热带风暴、地震)的修復、搜尋和搶救,勘查無人地帶等。因此,(我們)在無線環境裡提出了一個新型的網路架構。它被稱為隨建即連無線網路,也被稱作 “多跳” 無線網路。這樣的網路由大量的無線結點組成,可以全都是移動的。他們在自身之中動態地創造一個無線網路,而無需使用任何基礎設施或管理的支援。隨建即連網路是自我創造、自我組織和自我執行的。他們在由相互作用的自我控制和管理功能中形成一個隨建即連網路。有些專用術語,我不太清楚台灣是怎麼叫的,你自己斟酌吧。這篇東西應該是台灣人自己寫的吧。英文很不錯,可惜有些地方不像是老外的用法,很會玩弄語法倒是真的。你在學 Cisco 嗎?
