1. A node, comprising: a memory; and a processor coupled to the memory and configured to execute processes including: constructing a Guaranteed Time Slot (GTS) binary tree; storing the constructed GTS binary tree and pre-storing GTS request information of all neighboring nodes within a collision domain of a local node and reservation history information of the local node; constructing an HELLO packet, the HELLO packet comprising GTS request information of the local node or comprising GTS request information of the local node and GTS request information of at least one neighboring node within the collision domain of the local node; broadcasting the constructed HELLO packet, so that a node receiving the HELLO packet performs slot reservation according to information contained in the HELLO packet; updating total traffic within a collision domain of a sink node according to a received HELLO packet; determining a authenticating result given by a sender of the HELLO packet to the locally requested GTS; merging a GTS list in the HELLO packet with a local GTS table; and authenticating a GTS requested by the sender of the HELLO packet.
