In this paper, we propose a method that extends the lifetime of wireless sensor networks by using multiple mobile sink nodes. The proposed method determines the positions of multiple sink nodes based on remaining battery levels of sensor nodes. When a sink node is moved, the new position of the sink node is determined considering the distance to other sink nodes and the distance to the sensor node with the lowest remaining battery level. The proposed method also considers remaining battery levels in constructing routing tables. We conduct a comparative evaluation of the existing and proposed methods via simulation to demonstrate the effectiveness of the proposed method.
