摘要: Ad Hoc网络的虫洞攻击危害较大且难以防御。为此,提出一种基于时间和跳数的安全路由方法。将时间差值和跳数差值作为2个限制量,分别与规定值进行比较,判断并抛弃可能存在虫洞攻击的路由,并选择相对安全的路由,建立可信的数据传输通道。NS2仿真结果表明,该方法可提高虫洞攻击的检测率,降低数据传输的丢包率。

Abstract: For Ad Hoc network is vulnerable to the wormhole attack and wormhole attack is dangerous and difficult to defend, this paper proposes a secure routing method based on time and number of hops. By comparing two limits of the time difference and the hop number difference, it effective chooses the safer route and abandons the route which may exist wormhole attack in order to establish the credible data transmission channel. NS2 simulation experimental result shows that this method can significantly improve the wormhole attack detection rate and reduce the packet loss rate in data transmission.

Key words: Ad Hoc network, wormhole attack, secure routing, data transmission, packet loss rate
