Claim Text:
1. A transmission control method performed by a node constituting an ad-hoc network, the transmission control method comprising: transmitting data to a first candidate neighboring node for a destination of data selected by referring to a routing information table stored in a storage module, the routing information table associating the destination of data with a neighboring node and flag information indicative of whether a route reaching the destination from the neighboring node is effective, wherein when the flag information is effective, the data can reach the neighboring node and the destination from the neighboring node, when the flag information is not effective, the data can reach the neighboring node but the data cannot reach the destination from the neighboring node; determining whether a route reaching the destination from a second candidate neighboring node other than the first candidate neighboring node for the destination of data is effective based on flag information of the second candidate neighboring node by referring to the routing information table when the transmitting of the data fails; retransmitting the data to the second candidate neighboring node when the second candidate neighboring node for which the route reaching the destination from the second candidate neighboring node is effective is present as a result of the determining; and aborting the retransmitting of the data when no second candidate neighboring node for which the route reaching the destination from the second candidate neighboring node is effective is present.
