Research On Data Collection Methods And Transmission Methods In Sensor Networks

This paper mainly studies the data transmission and collection in sensor networks.Firstly,a data transmission algorithm suitable for rechargeable sensor networks is proposed.The algorithm establishes a specific band structure in the network,and selects two core nodes on the band to complete the data transmission task.Firstly,the scheme of candidate core nodes is proposed to implement the mechanism of node charging and rotation,and then the problem of data transmission is solved.When selecting the forwarding node,the algorithm queries the schedule of the superior node to determine the optimal forwarding node and ensure the timeliness.Finally,it is verified by experiments that the proposed method has good performance in saving transmission consumption and ensuring transmission timeliness.In view of the problems existing in the existing clustering based data algorithm,a data collection algorithm based on the optimization of fuzzy logic is proposed.The algorithm solves the problem of uneven clustering existing in the existing clustering algorithm by using the optimization of kmeans algorithm and fuzzy logic algorithm for clustering.On the premise of ensuring the uniform distribution of the initial cluster head and the nodes in the cluster,the initial cluster head node and the alternative cluster head node are calculated by the relationship between energy and distance,so as to solve the problem of balancing the energy of nodes in the network.Finally,the effectiveness of the proposed algorithm is proved by experiments and comparison with the optimized kmeans algorithm(KMP algorithm).
