无线自组织网络基于网格匿名组播安全路由协议
摘 要: 已有的无线自组织网络匿名算法大多针对某个阶段或步骤,对此提出一种基于网格的匿名组播安全路由协议。首先,为簇首发送网络管理消息设置了随机的发送间隔,降低被窃听的成功率;然后,为自组织网络的各种消息设计了统一的消息格式,以免窃听者通过格式分析获得有效的信息;最后,基于网格对无线网络的分簇与路由进行管理,新节点加入簇时,无需向簇首发送请求即可与簇内成员建立有效的链接与路由,由于该算法考虑了整个网络生命期,因此可全面地保证网络的匿名性与安全性。仿真实验结果表明,该方法使得移动自组织网络具有较好的连接性与隐私保护能力。

Abstract: Since most of the existing anonymous algorithms in Ad hoc network are aiming at some phases or steps of network, a mesh?based anonymous multicast security routing protocol is proposed to solve that problem. A random sending time interval is set for controlling message from cluster head to reduce the success rate of eavesdropping, and then a united message format is designed for all kinds of messages of Ad hoc to prevent the adversary getting efficient information by the format analysis, lastly, the mesh?based management is designed for wireless network clustering and routing, by which when new nodes are added to the cluster, it is unnecessary to send a request to cluster head for setting up efficient linkages with the members inside the cluster. As the proposed algorithm considers the lifetime of the entire network, the anonymous and security features can be ensured in the whole lifetime. The simulations results show that the proposed method enhances the network connectivity and privacy protecting performance of Ad hoc network successfully.
Keywords: mobile Ad Hoc network; wireless sensor network; anonymous multicast protocol; security routing protocol; wireless mesh network

大规模无线自组织网络的各种应用场景(如无线视频会议、VANET系统等)均需要将节点分簇管理,以提高网络的管理效率,簇首的安全与网络的隐私保护是此类无线自组织网络的重要问题,然而目前仅有少量关于无线自组织网络分簇管理的安全性研究[1?2]。匿名性、位置信息与无关联性通信是无线网络的三大隐私信息,一旦攻击者获得网络的隐私信息,则可对网络进行毁灭性攻击[3]。然
