中文摘要：
针对无线传感器网络中分簇路由算法中存在的＂热区＂问题,提出了一种基于虚拟区域划分的非均衡簇路由算法.算法将簇划分的任务交由能量无限制的汇聚节点完成,使得靠近汇聚节点的内层簇的规模小于外层簇的规模.在簇的结构中引入了主、从簇头节点,从而实现了分布式簇头选举工作,同时在分簇过程中避免了每个阶段的能量消耗.将ARMA预测模型引入到主簇头节点的更换过程中,从而避免了主簇头因为能量完全消耗而死亡,也避免了因为主簇头死亡而造成网络分割,降低网络的生存时间,利用NS2.31仿真平台对基于虚拟区域划分的非均衡簇路由算法进行了仿真验证,结果表明与传统路由算法相比,该算法延长了WSN的生存时间,有效提高了WSN网络健壮度.
英文摘要：
Proposes unequal clusters of routing algorithm based on divided virtual region for ＂thermal region＂ in the wireless sensor network.The routing algorithm gives the task of clusters divided to sink node with non-limited energy,therefore,the scale of inside cluster layer which near the sink node is smaller than outer layer cluster.To realized the distributional election work of cluster head and avoided energy consumption in each wheel,we take main and vice cluster head into the structure of clusters.The ARMA forecast model has been intruduced into the switch process of main cluster head,therefor it has not only avoided main cluster head dies because of energy consumes completely,but also avoided the network divided as well as the short life of the network caused by the death of main cluster head.Compared with the tradition routing algorithm,the simulation result in the NS2.26 indicated that this routing algorithm prolonged the life of WSN.
