In large-scale wireless sensor networks, since it is impossible to control the whole system intensively, a self-organized control technique based on local information is proposed. However, there is no guarantee that operation of the whole network is controllable only by self-organized control in the desirable direction. In this study, we propose a control technique for the potential value of sink nodes by from the outside in a large-scale sensor network that consists of multiple sink nodes. Simulation experiments shows that the way a sensor node realizes routing only with a potential value in self-organization is effective. Furthermore, we showed that this architecture is applied to smart metering systems.
