Abstract
Each of the nodes counts the number of other nodes located in a communication area of the node among nodes in a multi-hop network, and determines the number of times to retransmit a frame based on the counted number of the other nodes. Each of the nodes transmits a frame to a destination node, and repeats retransmission of the frame the determined number of times until receiving a response to the transmitted frame. Subsequently, each of the nodes changes a route to the destination node to another route when it does not receive the response after repeating the retransmissions the determined number of times.
