摘　　要：针对多对一的周期性数据收集应用,提出一个低开销的逐跳多径路由协议LOMP,综合利用定期和实时估计器评估链路质量,在此基础上实现高质量的多径路由。与现有的多径路由协议相比,LOMP并不提供端到端的节点独立的多径路由,而只是确保在报文的每一跳转发过程中都有多条路径可用。仿真结果表明LOMP能够提高选路质量,以较小的能量开销提高数据传输的可靠性。A low overhead routing protocol for many-to-one data collection in wireless sensor networks named LOMP was proposed. The real-time link quality estimation is combined with periodical link quality estimation to provide reliable routing selection in face of the poor link quality in sensor networks. Instead of providing end-to-end node-disjoint multipath routing, LOMP only ensures data forwarding for hop-by-hop multipath. The simulation results indicate that LOMP can greatly reduce routing overhead and improve routing reliability at the same time.
