基于模糊评判的无线传感器网络簇间数据转发算法OA北大核心CSTPCD

Due to the high energy consumption and low forwarding efficiency of wireless sensor networks in the process of inter cluster data forwarding,data is prone to failure in the process of forwarding.Therefore,an inter cluster data forwarding algorithm based on fuzzy evaluation is proposed for wireless sensor networks.The wireless sensor network model and communication model are defined,the opera-tion mode of the node and the energy consumed by forwarding data are defined,a fuzzy comprehensive evaluation model is built,trape-zoidal membership function are defined to calculate the similarity and activity of sensor nodes,the best forwarding node if found,the data forwarding task is completed.The simulation results show that the value of the maximum number of dead cycles and network failure cy-cles of the first node of the proposed algorithm are 167 and 178.When the number of simulation cycles reaches 1 000,the remaining network energy and the average node energy of the algorithm are 4 J and 0.01 J respectively,which proves that the proposed algorithm can consume the least energy in the process of data forwarding and complete the task of data forwarding efficiently.
