概要 In a wireless sensor-actuator network (WSAN), sensors and actuators are interconnected with wireless channels. Messages sent by sensors might be lost due to collision if multiple sensors simultaneously send the messages in a channel. In sensing applications, sensed values are in nature required to be sent to actuators in a real-time manner. If a message is detected to be lost, the lost message is retransmitted. It takes at least three rounds to retransmit a lost message. We have to reduce the number of messages retransmitted to realize the real-time communication. We newly propose a data transmission procedure where data in a message m_1 is redundantly forwarded to the destination node by another message m_2 sent by the receiver node of m_1. Even if the message m_1 is lost, the destination node s can receive the data in m_1 if s receives m_2. In addition, we have to reduce the energy consumption of a sensor where only some, of the sensors send sensed values.
