Abstract
In a wireless multi-hop network, a node directly connectable in one hop at a relay node installation point candidate is detected. When a node-to-node connectability diagnosis result demonstrates that an isolated node exists, the candidate enabling a connection to the base station and yet the candidate enabling a one-hop connection to the isolated node is selected as a relay node. When an isolated node still remains, the candidate enabling one-hop connections both to the remaining isolated node and to the isolated node that has newly become connectable to the base station is additionally selected as a relay node from among candidates that do not enable a connection to the base station. The route of 'the remaining isolated node>additionally added relay node>isolated node that has become connectable to the base station>base station' is established.
