Document Type and Number:
Japanese Patent JP6927072
Kind Code:
B2
Abstract:
A path selection apparatus for selecting a path when storing sensor reports from lower nodes in a packet and transmitting the packet to an upper node in a sensor tree including a plurality of nodes includes a node movement unit that selects a first node holding a child node under the first node in the sensor tree, and moves a second node under the subtree with the first node as a vertex to a position under a third node not belonging to the subtree in the sensor tree when a movement of the second node to the position under the third node decreases a total number of packets to be transmitted and received in the sensor tree.
