Collision-Free Beacon Scheduling Method based on Distributed Address Assignment Scheme

摘要

The invention scheduling the beacon using these addresses are attributes that are born the mutual collision in the network for providing a distributed address scheme, such as a ZigBee network and delay dispersion address assigned techniques anti-based beacon collision scheduling that minimizes the data It relates to a method. ; According to one feature of the invention, the time difference between the own beacon transmission to the beacons received from the parent device in a wireless network system (time offset consisting of a tree structure; T _n ) distributed according to his address, the address determined by the authorization mechanism obtained from the configuration, but their beacon transmission schedule, And ; here SD is a super-frame length, On is the value that reassessment of whether the couple first child is the device on the network during his brethren devices, Bd is provided with a sub-network address assigned a number distribution techniques avoid beacon collision based on the scheduling method that indicates the maximum number of router device which can have a depth d of the tree.
