一种水下无线网络安全机制关键技术

Research on key technology of the underwater wireless network security

针对目前水下无线通信网络安全存在的问题,在对网络拓扑结构和拓扑控制进行研究的基础上,分析现有成簇策略的特点及不足,然后提出基于信任和能量的成簇方法。本方法通过对成簇方式进行分段控制,在初始化阶段采用最小能耗策略实现全网成簇,在簇头重选阶段以能量因子和信任因子作为综合评价依据选取信任簇头,在拓扑维护阶段对簇内节点进行监控和维护,实现降低能耗和提高安全的目标。最终在模拟仿真中,通过与LEACH算法对比发现,本算法在能耗和安全性上都有很大的提升。

Aiming at the current problem of wireless communication network security under the water, on the basis of the research of topology and the topology of the network control, analyses the characteristics and deficiencies of the existing clustering strategy, and then proposed a clustering method based on trust and energy. The method based on clustering methods of sectional control, in the initialization phase by using the minimum energy strategies to achieve full network clustering, the cluster head reselection stage by energy factor and the factor of trust as a comprehensive evaluation according to the selected cluster head in trust, topology maintenance stage of intra cluster nodes for monitoring and maintenance, reduce energy consumption and improve the safety goal finally, in the simulation, by comparing with the LEACH algorithm, this paper finds that the proposed algorithm has greatly improved in energy consumption and safety.
