Abstract
A node performs multi-hop communication. The node includes a relay node determiner that determines a relay node from a plurality of relay node candidates having path information of a path to a master node. The relay node performs relaying. At least when communication frequencies of the relay node candidates are within a predetermined range, the relay node determiner determines the relay node so that a relay node candidate with a higher communication frequency is more likely to be determined as the relay node than a relay node candidate with a lower communication frequency.

A node that performs multi-hop communication, the node comprising:
- a relay node determiner configured to determine a relay node from a plurality of relay node candidates having path information of a path to a master node, the relay node being configured to perform relaying,
- at least when a number of lower nodes of each of the relay node candidates is within a predetermined range, the relay node determiner being configured to determine the relay node so that a relay node candidate having a larger number of lower nodes is more likely to be determined as the relay node than a relay node candidate having a smaller number of lower nodes.
A node that performs multi-hop communication, the node comprising:
- a relay node determiner configured to determine a relay node from a plurality of relay node candidates having path information of a path to a master node, the relay node being configured to perform relaying,
- at least when communication frequencies of the relay node candidates are within a predetermined range, the relay node determiner being configured to determine the relay node so that a relay node candidate with a higher communication frequency is more likely to be determined as the relay node than a relay node candidate with a lower communication frequency,
- the communication frequency being determined based on a communication frequency estimated value of the relay node candidate, and
- at least when the communication frequency estimated values of the relay node candidates are within a predetermined range, the relay node determiner being configured to determine the relay node so that a relay node candidate having a higher communication frequency estimated value is more likely to be determined as the relay node than a relay node candidate having a lower communication frequency estimated value.
A communication method for a communication system that performs multi-hop communication, the communication method comprising:
- determining a relay node from a plurality of relay node candidates having path information of a path to a master node, the relay node being configured to perform relaying,
- at least when a number of lower nodes of each of the relay node candidates is within a predetermined range, the relay node being determined so that a relay node candidate having a larger number of lower nodes is more likely to be determined as the relay node than a relay node candidate having a smaller number of lower nodes.
