考虑节点剩余电量及簇头间距的簇划分WSN容错分组

Fault Tolerant Packet Classification for WSN with Residual Power of Nodes and Cluster Head Spacing

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 process of data routing in wireless sensor networks, the environment, energy consumption, and equipment will affect the operation of WSNs, which could affect the use of the WSNs cycle and then increase the network operating costs, so, the cluster based fault tolerant wireless sensor packet protocol is proposed based on the residual energy of nodes and the distance between cluster heads. Firstly, the distance between the cluster head and the sensor nodes, also with the distance between the cluster head and base station are used to adaptively select the next cluster head. Secondly, the lowest energy consumption is used to guide the selection of the next CH, and the fault tolerance mechanism is introduced to improve the efficiency of data transmission and reduce energy consumption; Finally, the advantages of FTCD packet protocol in energy consumption and data transmission efficiency are verified by experiments.
