摘要：OLSR（Optimized Link State Routing Protocol，最優鏈路狀態路由協議，RFC3626）協議是應用于MANET網絡的一種先應式表驅動路由協議，其拓撲發現過程是實現有效通信的關鍵。本文提出了一種基于C++的OLSR協議拓撲發現的實現方案。該方案采用模塊化面向對象設計方法，結合C++語言的特點使用了一些新的實現方法，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
