TREE ROUTE DETERMINATION DEVICE AND TREE ROUTE DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To efficiently determine a tree route in creating a sensor tree composed of sensor nodes.;SOLUTION: A system including a root sensor node in a sensor tree and a floating sensor not connecting with the sensor tree includes a tree route determination device for determining connection relation between the floating sensor and a master tree sensor node adjacent to the floating sensor. The tree route determination device comprises: sensor information acquisition means for acquiring information on the floating sensor for each level defined as the number of hops from the route sensor node; and route determination means for making the floating sensor, as a new tree sensor node at a level at which information on the floating sensor is acquired, connect with a position directly under a master tree sensor node whose level is one level smaller.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2017,JPO&INPIT
