摘　　要：为提高城市地下综合管廊的信息化管理水平,实现地下监测数据的高效传输,针对目前无线物联网相关技术在地下场景中数据长距离传输不可靠问题,提出一种通过电力线载波通信(Power Line Communication, PLC)实现地下监测节点多跳长距离数据传输的路由算法。算法利用链路状态结合城市综合管廊监测节点物理位置对中继节点进行选择和组网。同时,根据路由子树的负载均衡指数,对路由树叶子节点进行调整,实现负载均衡,进一步提升传输效率。通过仿真工具将该算法与基于邻居节点信息的路由算法(NKR)和开放最短路径优先算法(OSPF)进行对比实验,表明所提算法丢包率和时延等性能均有显著提升,可有效提高地下综合管廊监测数据传输效率。To improve the information management level of underground utility tunnel and monitoring data transmission efficiency, this paper present a PLC-based(Power Line Communication, PLC) multi-hop data transmission routing algorithm, which can tackle the data transmission reliability problem of Wireless Sensor Network in the underground communication. The locations of monitoring nodes and link states are comprehensively taken into consideration when choosing the relay node and constructing the routing tree. Furthermore, a load balance mechanism is utilized to optimize the routing tree by computing the Sub-tree Balance Index and adjusting the leaf node. Finally, comparative experiments with NKR(Neighborhood Knowledge-based Routing) and OSPF(Open Shortest Path First) algorithms are performed using the MATLAB simulation tool. The results show that our proposed algorithm can obtain better performance in terms of latency and packet loss rate.
