Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, many studies have been conducted on incorporating mobile sinks into sensor networks
and controlling their mobility in order to improve network connectivity and extend network lifetime. In existing
methods, however, all or some nodes must know their own geographic location using special devices such as GPS
receivers. Yet it entails a high cost when each node is equipped with a GPS receiver. Moreover, GPS-based local-
ization cannot provide reliable location estimation in indoor environments and in the presence of obstacles. In this
paper, we use a patrolling robot as a mobile sink and propose a controlled mobility to navigate the mobile sink
towards the targeted sensor nodes. In our method, the targeted node constructs a potential eld and the mobile
sink can approach the target node using that eld. We evaluate our method by implementing it into a cleaning
robot for a mobile sink. We show that the mobile sink with our proposed method can reach the targeted node in
about 5 min.
