In recent years,with the rapid development of electronic technology,wireless communication technology and embedded technology,wireless sensor network technology has attracted more and more attention in environmental monitoring,industrial,medical and other fields,and has become one of the key technologies in information field.In this paper,the problems of routing protocol and data fusion in wireless sensor networks are studied as follows:First,according to the LEACH algorithm to cluster uneven clustering routing and distribution of energy consumption when the problem of excessive,proposes a double cluster head clustering clustering algorithm based on the cluster head selection algorithm,the cluster head selection of two levels in good clusters,two cluster heads perform different to share the responsibilities,energy consumption and prolong the network life cycle;in the data transmission algorithm: the transmission mode of single hop and multi hop combination,can further balance the energy consumption of cluster head nodes.The simulation results show that the algorithm effectively prolongs the survival time of the network.Second,according to the problem of the randomness of cluster head election and the energy consumption of cluster head nodes,a dual cluster head clustering algorithm is proposed to optimize the cluster head selection algorithm.In a good cluster deployment of heterogeneous nodes as the first cluster head,according to another cluster head selection energy factors,two cluster heads perform different functions,wherein,the first cluster head by using the method of single hop and multi hop based information will be transmitted to the sink node,to share the energy consumption and prolong the network the purpose of life cycle.The simulation results show that the algorithm has good energy saving effect.Third,based on the double cluster head in second different redundant cluster head node clustering algorithm in data transmission,the communication volume,shorten the lifetime of the network,taking into account the linear correlation between the data of different attributes,through the introduction of cloud theory and least squares method,a weighted least square cloud data fusion algorithm.The simulation results show that the algorithm can eliminate redundant information,reduce the amount of data transmission,and effectively prolong the network life.
