Abstract
A sensor network systemis provided with a plurality of sensor nodes, . . . and configured to decide a parent node for each of the plurality of sensor nodes so as to form a network topology having a tree structure using each of the plurality of sensor nodes as a node. The sensor network system forms the network topology so that, with respect to each of the plurality of sensor nodes, the number of child nodes owned by the sensor node is close to a value obtained by multiplying a maximum containing number, which is a maximum number of sensor data that can be contained by one packet, by a natural number ().
