NODE DEVICE AND COMMUNICATION METHOD

摘要

A node device includes a transmitter, processor, and a receiver. The receiver receives a packet from an adjacent node device. The processor generates a cluster list and a first hello packet. The cluster list records device identification information of a node device included in a cluster. The cluster is a group of node devices for which route information is stored. The first hello packet reports the route information with cluster identification information of the cluster. The transmitter broadcasts the first hello packet. Upon receipt of, from a free-node device that does not belong to a cluster, a second hello packet that includes information that associates the cluster identification information with device identification information of the free-node device, the processor adds the device identification information of the free-node device to the cluster list until a number of node devices recorded in the cluster list reaches a threshold.

1. A node device within a network that includes a plurality of node devices, the node device comprising:
a receiver configured to receive a packet from an adjacent node device; a processor configured to
generate a cluster list that records device identification information of a node device included in a cluster from among the plurality of node devices within the network, the cluster being a group of node devices for which route information is stored, andgenerate a first hello packet that is a hello packet used to report the route information with cluster identification information of the cluster being stored in this hello packet; and a transmitter configured to broadcast the first hello packet, wherein upon receipt of, from a free-node device that does not belong to a cluster, a second hello packet that includes information that associates the cluster identification information with device identification information of the free-node device, the processor adds the device identification information of the free-node device to the cluster list until a number of node devices recorded in the cluster list reaches a threshold.
