Keeping the network coverage and maintaining high connection are the goal of the wireless sensor networks (WSN). Therefore, network coverage becomes the focus of research, then an Energy aware-based complete coverage and highly connectivity scheme is proposed in this paper, which named EACC. In EACC scheme, firstly, the relationship between overlapping area of two sensor nodes’ sensing area and distance between them is analyzed, and results show that overlapping area is non-linearly reduced with the increase of distance. Secondly, each cluster head (CH) makes use of the coverage area and residual energy of nodes to determine whether the node is the active node or sleep node. Moreover, in order to maintain the connectivity, any one node is in another node communication range. Finally, compared with similar schemes, extensive simulations results show that EACC scheme outperforms other schemes.
