摘　　要：针对物联网节能分簇路由受到物联网链路状况的影响,导致物联网的性能下降,以提高物联网的性能为目的,提出基于网络坐标的物联网节能分簇路由算法。在网络坐标的基础上,为了缓解离物联网基站较近的簇首出现通信过载问题,设定临界值为物联网节能簇首选择不同通信方式。通过对决策矩阵进行加权标准化处理,构建了物联网节能簇间通信路径。由于网络坐标只适用于网络节点密集的场合,采用自由空间模型来表示物联网节点收发数据过程中的能耗,根据物联网中最佳簇头数目的计算,确定了最佳簇头数目。结合物联网节能分簇路由算法的实现流程,实现了物联网节能分簇路由算法的设计。实验结果表明,基于网络坐标的物联网节能分簇路由算法不仅可以降低节点死亡率,还可以延长物联网的生命周期,从而使物联网的性能得以提高。In order to improve the performance of the Internet of Things,an energy-saving clustering routing algorithm based on network coordinates was proposed.Based on the network coordinates,in order to alleviate the communication overload problem of cluster heads closer to the Internet of Things base station,the critical value was set to select different communication methods for the energy-saving cluster head of the Internet of Things.Through the weighted and standardized processing of the decision matrix,the communication path between the energy-saving clusters of the Internet of Things was constructed.Since the network coordinates are only suitable for occasions where dense network nodes are dense,the free space model was adopted to represent the energy consumption in the process of sending and receiving data of the Internet of Things nodes.According to the calculation of the optimal number of cluster heads in the Internet of Things,the optimal number of cluster heads was determined.Combined with the implementation process of the energy-saving clustering routing algorithm of the Internet of Things,the design of the energy-saving clustering routing algorithm of the Internet of Things was realized.The experimental results show that the energy-saving clustering routing algorithm based on network coordinates can not only reduce the node mortality,but also prolong the life cycle of the Internet of Things,thereby the performance of the Internet of Things can be improved.
