Patent number: 10004105Abstract: Provided is a network self-healing method in which, when a link between a parent device and a child device breaks down in a wireless communication network of a cluster-tree structure in which a main communication device (referred to an access point (AP)) manages network operation, routers that are devices capable of having their child devices, and end devices that are devices incapable of having their child devices are associated with each other in a parent-child device relationship, the link is restored. When a router becomes an orphan device, the router makes network re-association in a cluster unit while maintaining synchronized operation with its child devices, and thus time, energy and signaling burden for network self-healing is largely reduced.Type: GrantFiled: December 20, 2016Date of Patent: June 19, 2018Assignee: Seoul National University R&DB FoundationInventors: Yong Hwan Lee, Jin Seok Han, Jae Seok Bang, Dong Kwan Kim
