碩士 === 東海大學 === 資訊工程學系 === 99 === Mobile ad hoc networks are usually deployed in many environments, such as the environment is not easy to build by wired or fixed nodes. The nodes in the network are unattended and easy be attacked because of congenital weak physical protection. Mobile ad hoc networks are vulnerable to the denial-of-service (DOS) attacks. Flooding DOS attacks are new and powerful attacks against on-demand Ad Hoc routing protocols. In 2005, the single scheme proposed to resist such attack was the Flooding Attack Prevention. In 2006, another scheme to resist this kind of attacks was proposed by using Avoid Mistaken Transmission Table. In this thesis, we present a new and more efficient solution to inhibit flooding attack in Mobile ad hoc networks. In our scheme, legal nodes can use Priority and Trust Value and Neighbor Nodes List Table to distinguish attack nodes and refuse to forward packets for them, and hence the flooding attacks can be defended. According to the results of NS2 network experiment, we show that our scheme can inhibit the flood hit with lower costs and more efficient. Our scheme can defense attacker faster, and use a few storage.
