In this paper, based on LEACH protocol, improvement is made and the improved protocol DCDA-LEACH is proposed. DCDA-LEACH makes improvements to LEACH with data correlation and data aggregation as the core, introducing the thinking of regionalization. It divides the nodes into regions in accordance with the relevant characteristics of the data to improve the data correlation level within the clusters. Clustering process works with the regional restrictions to enhance data aggregation efficiency and reduce energy consumption. Multi-skip routing is used to reduce the number of cluster-heads which communicate with base station directly. The protocol, therefore, can balance the node energy and prolong the network life.
