| Summary: | 碩士 === 國立臺北大學 === 通訊工程研究所 === 98 === VANETs is a special network that derives from the improvement of wireless networking. The vehicle itself includes wireless equipment and, therefore, is able to connect with its neighboring vehicles while moving, without a wireless access point. Such attribute corresponds with MANETs. Thus, VANETs routing protocol can ally and develop with MANETs. One of VANETs’ many applications is vehicle safety service, such as notification of traffic accidents ahead and obtaining accurate position of calamity. These applications mark the importance of safety.
Nonetheless, currently the protocol of VANETs has not fully matured. This paper contributes by applying MANETs routing protocol, AODV, on VANETs, and finding out its disadvantages through in-depth discussion and analysis. Moreover, this paper also demonstrates the actual severe damages of AODV by attacking black hole and selfish node. With deeper understanding and wider recognition of the significance of safety issue, we can develop a tighter protocol, and build a better defense system that heaves safety reliability in the future.
