摘要:

抵抗攻击和评价节点的声誉值是可信MANET(Mobile Adhoc Network)中的重要内容,因此有必要建立一套有效的信任系统。为了解决网络中负载过高和监测信息可信性等问题,文章提出一种将节点分层的声誉管理系统,通过选择特殊的节点作为管理节点来收集监测信息并计算节点的声誉值,管理节点之间采用组播的方式进行交流。该模型能够有效区分恶意信息,提高监测信息的可信度,解决网络中信息收集的问题。同时,管理节点之间能够相互配合,有效识别并抵抗多种攻击。仿真实验结果证明了该模型的有效性。

关键词: MANET, 声誉管理系统, 组播, 攻击

Abstract:

Resisting attacks and evaluating the reputation values of nodes are important parts of trusted MANET(Mobile Adhoc Network), so it is necessary to establish an effective trust system. In order to solve the problems of overload and credibility of monitoring information in the network, etc., this paper proposes a node-hierarchical reputation management system that collects monitoring information and calculates the reputation values of nodes by selecting special nodes as management nodes. The management nodes communicate with each other by multicast. The model can effectively identify malicious information, improve the credibility of monitoring information, and solve the problem of information collection in the network. At the same time, management nodes can coordinate with each other to effectively detect and resist various attacks. Simulation results demonstrate the effectiveness of the model.

Key words: mobile adhoc network, reputation management system, multicast, attack
