摘　　要：物联网中大量采用电池供电的传感器节点,其有限的电量严重制约了网络寿命。为解决这一问题,文中从网络层入手,根据节点的空间分布特点,设计了一种自适应的节能路由选择机制。该协议通过构建并维护节点空间关联度模型,实现路由建立与数据转发中的电能消耗最小化,路由的选择与更新同时考量了距离因素和电量预测。仿真结果表明,在保持网络连接覆盖率的前提下,通过该自适应协议,网络寿命指标较基准的最短路径路由有30%以上的统计算法提升,在一定的节点密度下可达到40%以上,验证了该方法的有效性,为大规模物联网系统中节点的电量优化与网络寿命管理提供了解决方案。A large number of battery-powered sensor nodes are used in the Internet of Things,and their limited power seriously restricts the network life.In order to solve this problem,this paper starts from the network layer and designs an adaptive energy-saving routing mechanism according to the spatial distribution characteristics of nodes.The protocol minimizes the power consumption in route establishment and data forwarding by constructing and maintaining the node spatial correlation degree model.The selection and update of routes take into account the distance factor and power prediction at the same time.The simulation results show that,under the premise of maintaining the network connection coverage,through the adaptive protocol,the network life index can be improved by more than 30%compared with the benchmark shortest path route,and can reach more than 40%under a certain node density.This verifies the effectiveness of the method and provides a solution for node power optimization and network life management in large-scale Internet of Things systems.
