【摘要】 无线传感器网络是一种全新的信息获取平台,具有快速展开、适应性强等特点。对无线传感器网络及其路由技术进行了综述,介绍了分簇路由算法及其改进。首先对簇头的功能进行了改进,使它在能量消耗至某个阈值以下时可以在簇内选择代理,代替簇头进行工作。其次对分簇路由算法中簇头向汇聚点传输数据的方式做了一些改进,增多了最后一跳向汇聚点传输数据节点的数量,减轻了节点的负担,在一定程度上平衡了网络内能量的损耗。更多还原

【Abstract】 Wireless sensor network is a new information access platform with rapid expanding,strong survivability and other features,has wide application prospects.This paper reviews the wireless sensor network and its routing technology,and introduces the cluster-based algorithm and its improvement.Firstly,the function of the head of cluster is improved.If the value of the energy is consumed so much that it blows the threshold value,the head of the cluster can choose another node as the agent of the head of the cluster.Secondly,the paper makes some improvement in the way that the head of the cluster sends data to the sink node.The algorithm increases the number of the node that transmits data to sink node in the final jump.It can reduce the burden of nodes.To a certain extent,it can balance the lost of the network energy.更多还原
