提出了一种能量均衡的安全路由机制(LDEESR)
适用于周期性数据收集的传感器网络. LDEESR采用一种动态路由选择算法
该算法基于节点权值和高度值建立起一棵动态汇聚树
并利用类似于令牌传递的方式来选取树根
同时还用对称和非对称加密机制来保障路由的安全.在这种机制下
LDEESR能够以很低的开销组织网络中所有的节点
健壮网络拓扑
防范多种攻击.通过与基于群体的传感网络以及混合式高能效分布式聚类协议的仿真比较表明
LDEESR可降低和均衡所有节点的能耗
减小汇聚时延
延长网络的生命期.
A low delay energy equalizing secure routing scheme(LDEESR)that is suitable for gathering data periodically in wireless sensor networks is proposed. LDEESR utilizes a dynamic route selecting algorithm based on weight-value and height-value of nodes to establish a dynamic gathered tree that is similar to the token passing to elect the root of the tree. LDEESR also uses symmetrical and asymmetrical encryption mechanisms to guarantee the routing security
under which LDEESR can organize all the nodes with low overhead and is perfectly robust against topology changes and many attacks. Simulation results show that compared with group-based sensor network(GSEN )and(hybrid
energy-efficient distributed(HEED)
LDEESR can decrease and equalize the energy consume of all nodes
lessen data gathering delay
and extend the network lifetime as well.
