METHOD FOR CONNECTING CHILDREN NODE OF WIRELSS SENSOR NETWORK AND WIRELESS SENSOR NETWORK SYSTEM THEREOF

摘要

PURPOSE: A method for connecting a child node of a wireless sensor network and a wireless sensor network system thereof are provided to minimize the re-attempt and collision in data transmission by requesting the connection from plural parent nodes after checking a child node connection state of plural parent nodes. CONSTITUTION: A child node collects connection state information from plural parent nodes(S10), and the connection state information is the information on the number of connected child nodes and a child node connection allowance number of each parent node. Through the connection state information, the connection request order of plural parent nodes is determined(S20). According to the connection request order, the connection of child node is requested from plural parent nodes(S30). The parent nodes are connected to the child nodes.
