摘　　要：主要研究传感器网络安全和能量高效的层簇式路由协议机制。在深入分析现有LEACH协议所面临的安全威胁的基础上,提出了一种动态的、基于分区自治的层簇式安全路由协议DZS-LEACH。其核心思想是,在多跳路由中融入动态密钥管理,使协议适应无线传感器网络动荡的拓扑结构,增强了协议的延展性;同时,DZS-LEACH通过分区自治避免远离基站的节点直接与汇聚节点通信,以均衡节点能耗。仿真实验表明,改进的路由协议DZS-LEACH大大减少了因网络攻击而造成的数据流失,增强了抗攻击能力,显著降低了网络能耗,延长了网络生存时间。This paper focused on the performance enhancement of the typical LEACH protocol in security and energy efficiency in wireless sensor networks.Considering security threats faced by the existing LEACH protocol,we proposed a novel dynamic hierarchical cluster-based zone-spanned secure multi-hop routing protocol,so called DZS-LEACH.The main idea is to introduce a dynamic key management scheme in the multi-hop routing protocol to provide communication protection.The DZS-LEACH enables,on the one hand,the scalability of routing mechanism and adaptation to the dynamic network topology,on the other hand,balances energy consumption by means of partition autonomy and avoids long-distance communication between sensor nodes and sink node.Our simulation experiments demonstrate that the proposed DZS-LEACH may enhance defense ability and reduce data loss caused by network attacks.Meanwhile,the energy consumption is reduced significantly and the network lifetime is extended.
