摘　　要：基于冶金企业设备监测的背景提出了一种无线传感器网络多跳同步时分协议.该协议采用自组织的层次拓扑控制方式,以簇头构成系统的骨干网,通过可靠路由方式传输数据.簇内节点组成局部网络以较小的发射功率采用分时多跳的方式将数据传输到距离较远的簇头,通过同步休眠机制降低功耗、满足传输时延要求.在冶金企业实际设备监测系统中的应用表明该协议具有扩展性强、传输可靠、信号延迟小和功耗低等特点.A kind of multi-hop and synchronous time-division protocol for wireless sensor networks based on equipment monitoring of metallurgy industry was proposed. The protocol employs self-organized and hierarchical topology. Cluster headers structure backbone network to forward sensor data to the sink node. Nodes in cluster transmit data in a lower radio power to the cluster header by multi-hop and time-division, they reduce power loss and transmission delay by synchronous sleeping-scheme. Application in an equipment monitoring system of met- allurgy industry indicates that this protocol has the characteristic of strong extension, reliable transmission, small signal delay, and low power loss.
