在无线传感器网络(Wireless Sensor Networks,WSNs)数据分组协议过程中,环境因素、能耗因素以及设备因素对于WSNs正常运行影响很大,会影响WSNs使用周期进而增加网络运行成本,对此,从提高WSNs网络设备容错性能角度,提出考虑节点剩余电量及簇头间距的簇划分容错无线传感器分组协议(clustering based fault tolerant distributed,FTCD)。首先,利用簇头(Cluster Head,CH)与传感节点间距、基站与CH间距及CH中电池能量剩余情况,进行CH的自适应选取。其次,采用能耗最低方式,对下一CH选取进行指导,并引入容错机制,提高数据传输有效率,进而降低能耗;最后,通过实验对比,验证了FTCD分组协议在能耗及数据传输效率上的优势。
In the Wireless Sensor Networks (WSNs) data packet protocol process, the environmental factors, energy consumption factors and equipment factors have a great impact on the normal operation of WSNs, which will affect the WSNs life cycle and thus increase network operating costs. In this regard, WSNs network equipment, we propose a clustering based fault tolerant distributed (FTCD) system that considers the remaining capacity of the nodes and the cluster head spacing. Firstly, adaptive selection of CH is performed by using Cluster Head (CH) and sensing node spacing, base station and CH spacing and remaining battery energy in CH. Secondly, adopting the lowest energy consumption mode to guide the next CH selection and introducing a fault-tolerant mechanism to improve data transmission efficiency and reduce energy consumption. Finally, the experimental verification shows that the FTCD packet protocol has better performance in terms of energy consumption and data transmission efficiency On the advantages.
