摘要
在分析现有信任管理机制的基础上提出了一种适用于水下分簇无线通信网络的分级信任管理机制。针对现有信任管理机制存在的问题和水下无线通信网络的安全需求,从包正常转发率、包的完整性、能量因素三方面对节点行为进行信任评估,采用直接信任值合成方法,将信任值的计算和管理分为成员节点、簇头节点、网关节点三级,实现了分级信任管理。仿真结果表明该信任管理机制能有效降低恶意节点对网络数据传输和吞吐量的影响并提高系统的安全性。
In this paper,the existing trust management mechanisms are studied.Based on the analysis and research,a hierarchical trustmanagementmechanism is proposed for cluster-based underwater wireless communication networks.To solve the problem in existing trust management mechanisms and to satisfy the security requirements of underwater wireless communication networks,we propose a hierarchical trustmanagementmechanism.The mechanism evaluate nodes＇behaviours from the successful rate of packets forwarded,the integrity of packets,and the energy factor.The direct trust value method is utilized,and the compution of trustvalue is devided into three levels.The proposed hierarchical trust management scheme is simulated and validated.The experiment results show that the hierarchical trust management scheme improves the security of underwater wireless communication networks effectively.
