Transmission apparatus, transmission method, reception apparatus, and reception method

A transmission method of a transmission apparatus, the transmission apparatus including

• a transmission control section adapted to control transmission of communication data to a reception apparatus at a communication time of day and a communication frequency based on individual identification information of the transmission apparatus itself and communication interval information shared by the transmission apparatus itself and the reception apparatus, wherein
• the transmission control section controls, in specific communication, the transmission of the communication data to the reception apparatus at the communication time of day and the communication frequency based on group identification information set for a group to which the transmission apparatus itself belongs when a plurality of transmission apparatuses including the transmission apparatus itself is divided into a plurality of groups and the communication interval information shared by the transmission apparatus itself and the reception apparatus.

A reception apparatus comprising:

• a reception control section adapted to control reception of communication data at a communication time of day and a communication frequency based on individual identification information of a plurality of transmission apparatuses and communication interval information shared by the transmission apparatuses and the reception apparatus itself, wherein
• the reception control section controls, in specific communication, the reception of the communication data at the communication time of day and the communication frequency based on group identification information set for a group to which the transmission apparatus belongs when the plurality of transmission apparatuses is divided into a plurality of groups and the communication interval information shared by the transmission apparatus and the reception apparatus itself.
