A Load-balancing Clustering Algorithm of WSN for Data Gathering

Xiang Lia Load-balancing Clustering Algorithm of WSN for Data Gathering (LCA-DG) is proposed based on load equalization. The LCA-DG uses the comprehensive weight value that composed of two factors, that distance between head and members and residual energy, to improve cluster members choice strategy for balancing load of each bunch, and uses optimization threshold value and receiving threshold value to avoid the new load imbalance that may occur after optimizing. So that the network lifetime can be further extended and the algorithm is suitable for large-scale sensor network.
