发明名称 Wireless Node Apparatus, and Multihop Wireless Lan System
摘要 Disclosed is a technique of transferring packets among wireless nodes as done in a tree type LAN, without intervening a root node to achieve efficient communications among the wireless nodes. According to the technique, a multihop wireless LAN is constructed by wireless nodes in such a way that it is determined whether or not a wireless node is a root node upon activation; when it is determined that the wireless node is the root node, status information is notified to wireless nodes to be connected, when it is determined that the wireless node is not the root node, wireless nodes to be connection candidates are requested to acquire status information, a higher-rank base station wireless node to be connected is selected and connected based on the status information, and when the wireless node apparatus is made a connection candidate later, status information is notified to wireless nodes. The wireless node includes bridge transfer means 101 which transfers packets from wireless nodes connected as higher-rank base stations to the higher-rank base station wireless node or the wireless node apparatuses connected as higher-rank base stations, or transfers a packet from the higher-rank base station wireless node to the wireless nodes connected as higher-rank base stations.
