PROBLEM TO BE SOLVED: To provide a radio communication method which enables data communication even to nodes which cannot perform direct data communication between them. SOLUTION: Whether or not radio communication is available between nodes is discriminated, and nodes 1A, 1B, 1C and 1C, 1D, 1E which are communicated with each other are grouped into groups GP1,GP2. In each node, when there is any node communicated with two groups or over, the node 1C is used for a bridge tying the different groups GP1, GP2. In the case of making communication with nodes between the different groups, communication is made via the node 1C decided as the bridge. When one node bridging over a plurality of the groups is used for the bridge, data communication is made between nodes of the different group and even when the nodes are a part or a radio wave obstacle is in existence, communication is made available. |
