| 摘 要： | 为在无线传感器网络中实现节能的路由转发,基于网络中节点能量有限和计算能力有限的特点,首先总结了目前已有的数据传输路由模式,在已有的基于簇的路由机制的基础上,在建立的簇中又进一步引入了"链"的概念.在簇建成后,将簇内的节点建成链,链首随机选择,每次由链首收集簇内数据后转发给簇头.这样每次向簇头传输数据的都是不同的节点,使得节点间的能耗更加均衡.仿真结果显示新模式有更好的节能效果,消除了节点的集中耗能,延长了网络的生存时间.研究表明,通过均衡节点能耗,可有效提高无线传感器网络性能.

| Abstract: | As the nodes of wireless sensor networks is power-limited and have limited computing resources,based on the cluster-based routing method,the paper proposes a new routing model,in which the" concept of link is presented.After the clusters are built,the nodes in it will be linked together to form a link.The header of link selects all data in the cluster and then transfers them to cluster-head.Different nodes will be selected as header to send data to cluster-head every time.The new model averages the node power that used.Simulation result shows that it has better power management performance and can prolong the lifetime of the network. |
