摘要：OLSR（Optimized Link State Routing Protocol，最優(yōu)鏈路狀態(tài)路由協(xié)議，RFC3626）協(xié)議是應(yīng)用于MANET網(wǎng)絡(luò)的一種先應(yīng)式表驅(qū)動路由協(xié)議，其拓撲發(fā)現(xiàn)過程是實現(xiàn)有效通信的關(guān)鍵。本文提出了一種基于C++的OLSR協(xié)議拓撲發(fā)現(xiàn)的實現(xiàn)方案。該方案采用模塊化面向?qū)ο笤O(shè)計方法，結(jié)合C++語言的特點使用了一些新的實現(xiàn)方法，主要完成了鄰居偵測、鏈路偵測、MPR選舉、HELLO消息處理、TC消息處理和拓撲計算等功能。

Abstract: OLSR(optimized link state routing protocol,RFC3626) is a kind of pre-active table driven routing protocol applied in MANET. Topology discovery process of OLSR is the key of efficiently realizing the communication. In this paper, a implementation plan of topology discovery of OLSR protocol was presented. The implementation was done in a modular and OOP fashion, using certain new methods combined with the characteristics of C++, which included the link sensing, neighbor detection, MPR selecting, HELLO Control processing, TC Processing and topology calculation.
Key words: MANET；Routing protocol；OLSR；Implementation；TC discovery
