路由算法在均衡物联网传感器节点能耗分析中的应用

Application of Routing Algorithm in the Energy Consumption Analysis of Sensor Nodes in the Internet of Things

传统路由算法只采用指定节点或路径实现数据转发,设定阈值的减少使簇头数量降低,能耗急剧升高,导致能量的非均衡消耗。为此,将一种新的路由算法应用于均衡物联网传感器节点能耗分析中。对传感器节点能耗进行研究,求出节点剩余能量。通过阈值得到本块候选簇头集合,把剩余能量较其他节点多,或者和本块中心之间距离较短的节点看作簇头节点。建立路由选择计算公式,按照前向路由节点剩余能量获取数据发送过程中簇间多跳路由。面向能耗均衡对路由进行更新,把传感器节点剩余能量划分成10个能量等级,按照网格能量等级确定等待时间,完成对簇首节点的更新处理,以保证节点能耗均衡性。实验结果表明,所提路由算法簇首节点选择合理,将其应用于均衡物联网传感器节点能耗的分析中,节点能耗较其他算法更加均衡性。

Traditional routing algorithms only use designated nodes or paths to achieve data forwarding.Setting threshold reduces the number of cluster heads and increases energy consumption,resulting in unbalanced energy consumption.To this end,a new routing algorithm is applied to the energy consumption analysis of the balanced sensor nodes in the Internet of things.The energy consumption of sensor nodes is studied,and the residual energy of the node is obtained.Through threshold,the candidate cluster head set of the block was got,and regard the remaining energy as more than other nodes or the shorter distance between nodes as the cluster head node.The formula of routing selection is established,and the multi hop routing is obtained in the process of data transmission according to the residual energy of the forward routing node.The energy balance is used to update the routing,divide the residual energy of the sensor nodes into 10 energy levels,determine waiting time according to the grid energy level,and update the cluster head nodes,so as to ensure the energy balance of the nodes.The experimental results show that the cluster head node selection is reasonable and applied to the analysis of the energy consumption of the sensor nodes in the internet of things.The energy consumption of the nodes is more balanced than other algorithms.
