Patent number: 10374881Abstract: Provided is a method of subscribing, by a terminal, to a network as a router or an end device in a wireless network (WN) having a tree structure including routers and end devices. Each router receives, from a parent router thereof, addresses which are usable independently for child routers and child end devices thereof, and classifies the addresses into a general address and a special address. A terminal wishing to subscribe to a network may subscribe to the network by using a special address of an end device, only when the terminal is unable to subscribe to the network by using a general address of the end device, thereby reducing depletion of addresses to be used for terminal subscription and facilitating network subscription of the end device.Type: GrantFiled: December 13, 2013Date of Patent: August 6, 2019Assignee: hyBee, Inc.Inventors: Yong Hwan Lee, Hyung Sin Kim, Jae Seok Bang
