Due to the ability to construct a large-scale sensing system by the cooperative behaviors of multiple sensor nodes, sensor networks are expected to be applied to many applications such as environmental monitoring. On the other hand, with the development of robotics technology in recent years, there has been many studies on sensors with a moving function (mobile sensors). In this paper, we propose an effective mobile sensor control method for sparse sensor networks. Our method uses two types of sensor nodes, fixed node and mobile node. The data acquired by nodes are accumulated on a fixed node before transferred to the sink node. In addition, our method transfers the accumulated data efficiently by constructing the communication route of multiple mobile nodes between fixed nodes. We also conducted simulation experiments to evaluate the performance of our method.
