In multi-hop data collection sensor network, nodes near the sink need to relay remote data, thus, have much faster energy dissipation rate and suffer from premature death. This phenomenon cause energy hole near the sink, seriously damaging the network performance. In this paper, the authors propose sink mobility with adjustable communication range to avoid the energy hole. First of all, they compute energy consumption of each node when sink is set at any point in the network through theoretical analysis.
