ABSTRACT:
A communication procedure has been developed that allows even a low-rate CPU to perform stable communication so as to realized wireless network nodes, which have a long communication distance and also have a long battery life. Each wireless network node decides its own time slot number by use of random numbers and transmits it after delaying the transmission by the number of time slots. When receiving the unique number from the wireless network node, a master unit transmits, to the wireless network node, an ACK signal together with the unique number. When receiving its unique number, the wireless network node gets into a sleep state for a period of time. In this way, each time communication is established, the number of active wireless network nodes is reduced.
