SELF-CONFIGURATION SYSTEM OF WIRELESS SENSOR NETWORK AND METHOD FOR SELF-CONFIGURING WIRELESS SENSOR NETWORK USING SAME

摘要

The present invention relates to a self-configuration system of a wireless sensor network, and a method for self-configuring a wireless sensor network using the same. In particular, the present invention relates to a method for self-configuring a cluster tree structure-based wireless sensor network (WSN), comprising the steps of: (A) a network structure determination step in which a coordinator, which is one of the parent devices, calculates the minimum network depth to connect the entire area of a WSN and the number of devices located within a communicable radius, and calculates the maximum number of child router devices and the maximum number of child end devices according to the network depth in each tree step, thereby determining a network structure; (B) a network connection step in which the parent device in each tree step selects and allocates an address to the child device according to a subscription request from the child device and allocates a superframe section for a child router device among the child devices; and (C) a data transmission step in which a router device having a packet searches for a routing path by comparing its own address with an address of a final destination of the packet and transmits the packet, and to a self-configuration system of the wireless sensor network using the same. The present invention can connect densely distributed devices distributed in a wide area to a network while maintaining the advantages of a conventional tree-structured network, such as the reduction of time required for network configuration, traffic by the exchange of control instruction messages, and a load for a routing path search, and thus can provide a WSN having an improved self-configuration performance when compared to the conventional method.
