Industrial wireless sensor networks(IWSNs) involve more reliability and certainty require-ments of data communication.A data sinking mechanism based on merging links with the same cycle and link competition(MLSCLC) for IWSNs is proposed.The link of the nodes with the same data col-lection cycle in the network is fused.Meanwhile,based on the calculation of links conflicts,the paral-lel time slot assemblage matrix is established.The time slot of links can be arranged via the method of link competition.Furthermore,the communication time slots of sensor nodes are obtained.Experi-mental results show that the proposed mechanism can ensure the stability of the netw ork while reduc-ing the average response time effectively.Thus,the data fidelity and network throughput can be in-creased.%工业无线传感器网络(industrial wireless sensor networks,IWSNs)对数据通信的确定性与可靠性有很高的要求,文章提出了一种基于同周期链路融合与链路竞争的数据汇聚机制(data sinking mechanism based on merging links with the same cycle and link competition,MLSCLC).根据网络中节点数据收集周期,对同周期节点的链路进行融合;根据链路的冲突关系,建立并行时隙集合矩阵,通过链路竞争方法,合理安排链路无冲突时隙,进而得到各个节点的工作时隙.实验结果表明,M LSCLC能保证网络的稳定运行,有效地降低了网络的平均响应时间,提高了数据传输的保真度和网络的吞吐率.
