Willson, James; Wu, Weili; Wu, Lidong; Ding, Ling; Du, Ding-Zhu New approximations for maximum lifetime coverage. (English) Zbl 1291.90044 Optimization 63, No. 6, 839-847 (2014). Summary: We present a new polynomial-time approximation scheme for the well-known Maximum Lifetime Coverage problem in wireless sensor networks. For any \(\epsilon > 0\), this scheme contains an approximation algorithm with performance \(3+\epsilon\), which improves the performance ratio \(4+\epsilon\) of previously known approximation in the literature.
