摘要: 针对用于工业过程自动化的无线网络(WIA-PA)在部署过程中存在的簇首数据负载分布不均衡问题,提出了一种支持负载均衡的新型成簇方法.根据WIA-PA的网络特征建立周期性数据吞吐量模型,通过改进WIA-PA网络的簇首选择算法和现场设备的入网流程,使现场设备入网时优先选择吞吐量相对小的路由器作为簇首,实现了网络拓扑结构依据流量自适应调整的成簇策略.测试结果表明,该方法在均衡簇首数据负载、平衡簇首能耗、延长网络生命周期等方面取得了良好效果.

Abstract: For the imbalance issue of data transmission among cluster-heads in wireless networks for industrial automation-process automation (WIA-PA), a new load-balanced clustering scheme is presented. A periodic data throughput model is firstly established based on WIA-PA network characteristics. Then a cluster-head selection algorithm and an improved joining method for field devices is proposed. The field devices prefer to select the router with the minimum throughput as their cluster-head,so as to adjust network topology adaptively according to the data traffic. The tests show that the proposed scheme can effectively balance the data traffic and energy consumption among cluster-heads,and extend the lifetime of WIA-PA networks.
