摘要 針對災后煤礦井下物聯網傳感節點能量難以及時補充的情況,提出一種基于兩階段簇頭選舉的節能分簇路由協議.該協議在初始簇頭選舉階段,通過引入節點能量因子篩選出能量水平高于網絡平均能量的節點作為候補簇頭節點;根據相鄰節點連通情況引入連通因子,基于能量因子與連通因子設計了災后重構網絡的選舉概率函數,通過選舉概率函數的計算進行簇頭選舉,形成初始分簇結構.在網絡運行階段,構建簇內選舉簇頭機制,通過周期性比較各簇簇頭節點剩余能量和閾值能量的大小來決定是否更換簇頭.仿真結果表明:采用該協議降低了煤礦物聯重構網絡的整體能耗,顯著延長了重構網絡的穩定周期,提升了重構網絡的穩定性.

Abstract In view of the fact that it is difficult to replenish the energy of the sensor nodes of IoT (internet of things) in coal mines after the disaster,an energy-saving clustering routing protocol based on two-stage cluster head selection was proposed.In the initial cluster head election stage,the node energy factor was introduced to select the nodes whose energy level was higher than the average energy of the network as the alternate cluster head nodes.According to the connectivity of adjacent nodes,the connectivity factor was introduced,the election probability function of the post-disaster reconstructed network was designed based on the energy factor and connectivity factor.The cluster head was elected through the calculation of the election probability function to form the initial clustering structure.In the operation stage of the network,the mechanism of electing the cluster head within the cluster was constructed.Whether to replace cluster heads was decided by periodically comparing the residual energy and the threshold energy of each cluster head node.Simulation results show that the protocol can reduce the overall energy consumption of the coal mine IoT reconfiguration network,significantly prolong the stability period of the reconfiguration network,and improve the stability of the reconfiguration network
