US 2026/0019918 A1 · SLAVE UNIT, MASTER UNIT, AND COMMUNICATION SYSTEM

Abstract

In a slave unit connected to a wireless mesh network, a second communication device (200) that receives a control message from a neighboring node, a protocol decision unit (330) that decides whether to process the control message with a first protocol or a second protocol, and an upward route construction unit (360) that calculates a first rank value in accordance with the first protocol and a second rank value in accordance with the second protocol using the route information contained in the control message, selects a master node from the neighboring nodes based on the first rank value and the second rank value, and records the ID of the master node in a routing table (902).

Claims20

Dependent claims

A slave unit connected to a wireless mesh network constructed based on a first rank value calculated by a first protocol, the slave unit comprising:

a communication device to receive one or more control messages indicating route information including rank information of a node, from one or more neighboring nodes;
and
processing circuitry:
to decide to perform a process in accordance with a second protocol with respect to the rank information;
to calculate a second rank value using the rank information in accordance with the second protocol based on a decision result by the processing circuitry, to select one node from among the one or more neighboring nodes based on one or more second rank values as a master node, and to record in a routing table an ID of the master node and the second rank value calculated using rank information of the master node;
and
to create a notification message to notify of the ID of the master node recorded in the routing table, and to transmit the notification message to a master unit.

4 more elements

A master unit connected to a wireless mesh network having a plurality of slave units as nodes, the master unit comprising:

a communication device to receive a notification message to notify of an ID of a master node and a communication system with the master node from a slave node;
and
processing circuitry:
to record, in a downward routing table, the ID of the master node, the communication system with the master node included in the notification message, and an ID of the slave node in an associated manner;
and
to refer to the downward routing table, to specify one or more nodes present in a route to a slave unit to be transmitted a downward message, and to create the downward message including an ID of a node and a communication system with the node.
