Abstract
A plural-data transmission Start message is transmitted prior to transmission of plural data to an intermittent operation type wireless communications terminal, and when transmission of plural data is completed, a plural-data transmission End message is transmitted. The terminal which received the plural-data transmission Start message can change over the sleep period of the aforesaid intermittent operation to a shorter sleep period. Thereby, an improvement in the response performance in the case of plural-data delivery can be simultaneously obtained while maintaining the low power performance of a sensor node.
