Abstract: Because Wireless Sensor Networks is the source limitation and the nodes consume the energy unbalanced,the lifetime of network will be reduced.To resolve the problem of unbalanced energy dissipation in the process of data gathering,an algorithm of data gathering based on balanced and efficiency energy dissipation is proposed.In the algorithm,the network arranged area is divided into rectangular grids with unequal size.According to the residual energy of nodes and the way of cluster rotate among the nodes of each grid respectively,and then using data fusion technology,this algorithm could prompt the balanced extent of energy dissipation and prolong the lifetime of the network by using the technology of data aggregation.The results of simulation and performance analysis shows that the algorithm is able to achieve better performance in aspects of balanced extent of energy dissipation and lifetime of network comparing with others typical algorithm of data gathering.
