<p>At relay units(GW1, GW2, GW3, RH2), root addresses which are included in packet data and are constructed by aligning addresses of the relay units existing at branch points in communication routes in passing order are decoded, then appropriate routes as a destination of the packet data are selected based on the decoded root addresses and own address stored previously, and then the packet data are transmitted to node terminals designated as the destination via the selected routes, whereby the packet data can be transmitted to a node terminal(N1, ..., N18) as the destination via the designated relay units(GW1, GW2, GW3, RH2). <IMAGE></p> |
