US 2026/0222967 A1 · NETWORK SELF-RECOVERY METHOD FOR WIRELESS NETWORK

Abstract

The present disclosure provides a method for self-healing in a multi-hop cluster-tree structured wireless communication network. The multi-hop cluster-tree structure includes the first router and the first tree structure in which the first router, operating as a cluster head, is connected to network devices in a parent-child device relationship. The method comprises: selecting, by the first router, a network device in the first tree structure as a role-switching device; performing a network self-healing process using the role-switching device; and handing over its router role to the role-switching device. The role-switching device is a network device can rejoin the network as a router in lieu of the first router when the first router is disconnected from its parent device.

Dependent claims

A method for self-healing in a multi-hop cluster-tree structured wireless communication network, wherein the multi-hop cluster-tree structured network includes the 1st router and the 1st tree structure in which the 1st router, operating as a cluster head, is connected to network devices in a parent-child device relationship, the method comprising;

a step in which the 1st router selects a network device in the 1st tree structure as a role-switching device;
a step in which the 1st router performs a network self-healing process using the role-switching device;
and
a step in which the 1st router hands over its router role to the role-switching device;
wherein the role-switching device is a network device that can rejoin the network as a router in lieu of the 1st router when the 1st router is disconnected from its parent device.

a step in which the 1st child device is selected as a role-switching device by the 1st router;
a step in which the 1st child device performs a network self-healing process by receiving a network address space from its parent candidate device;
and
a step in which the 1st child device allocates a network address space to the 1st router and takes charge of a router role of the 1st router;
wherein the 1st child device is a network device that can rejoin the network as a router in lieu of the 1st router when the 1st router is disconnected from its parent device.
