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... in sensor networks, sensor nodes located near the sink have to forward the data received from all other nodes to the sink, which depletes their energy very quickly. A moving scheme for the sink based on local......
