J. Cent. South Univ. Technol. (2009) 16: 0265-0268 DOI: 10.1007/s11771-009-0045-z A sink moving scheme based on local residual energy of nodes in wireless sensor networks TAN Chang-geng(谭长庚... residual energy was proposed. In the scheme, the sink periodically moves to a new location with the highest stay-value defined by the average residual energy and the number of neighbors. The scheme......
