Aodv for NS-2. A mobile ad-hoc network (MANET) is a kind of wireless ad-hoc network, and is a self-configuring network of mobile routers connected wirelessly. MANET may operate in a standalone fashion, or may be connected to the larger Internet. Many routing protocols have been developed for MANETs over the past few years. This project evaluated three specific MANET routing protocols which are Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Dynamic MANET Ondemand routing protocol (DYMO) to better understand the major characteristics of these routing protocols. Different performance aspects were investigated in this project including packet delivery ratio, routing overhead, throughput and average end-to-end delay.

DSP(digital singnal processor)是一種獨特的微處理器,是以數字信號來處理大量信息的器件。其工作原理是接收模擬信號,轉換為0或1的數字信號,再對數字信號進行修改、刪除、強化,并在其他系統芯片中把數字數據解譯回模擬數據或實際環境格式。它不僅具有可編程性,而且其實時運行速度可達每秒數以千萬條復雜指令程序,源源超過通用微處理器,是數字化電子世界中日益重要的電腦芯片。它的強大數據處理能力和高運行速度,是最值得稱道的兩大特色。

空間矢量脈寬調制(Space Vector Pulse Width Modulation) SVPWM的主要思想是:以三相對稱正弦波電壓供電時三相對稱電動機定子理想磁鏈圓為參考標準,以三相逆變器不同開關模式作適當的切換,從而形成PWM波,以所形成的實際磁鏈矢量來追蹤其準確磁鏈圓。傳統的SPWM方法從電源的角度出發,以生成一個可調頻調壓的正弦波電源,而SVPWM方法將逆變系統和異步電機看作一個整體來考慮,模型比較簡單,也便于微處理器的實時控制。 普通的三相全橋是由六個開關器件構成的三個半橋。這六個開關器件組合起來(同一個橋臂的上下半橋的信號相反)共有8種安全的開關狀態. 其中000、111(這里是表示三個上橋臂的開關狀態)這兩種開關狀態在電機驅動中都不會產生有效的電流。因此稱其為零矢量。另外6種開關狀態分別是六個有效矢量。它們將360度的電壓空間分為60度一個扇區,共六個扇區,利用這六個基本有效矢量和兩個零量,可以合成360度內的任何矢量。 當要合成某一矢量時先將這一矢量分解到離它最近的兩個基本矢量,而后用這兩個基本矢量矢量去表示,而每個基本矢量的作用大小就利用作用時間長短去代表。 在變頻電機驅動時,矢量方向是連續變化的,因此我們需要不斷的計算矢量作用時間。為了計算機處理的方便,在合成時一般是定時去計算(如每0.1ms計算一次)。這樣我們只要算出在0.1ms內兩個基本矢量作用的時間就可以了。由于計算出的兩個時間的總合可能并不是0.1ms(比這小),而那剩下的時間就按情況插入合適零矢量。 由于在這樣的處量時,合成的驅動波形和PWM很類似。因此我們還叫它PWM,又因這種PWM是基于電壓空間矢量去合成的,所以就叫它SVPWM了。
