RADIO NETWORK ALGORITHM WHICH USES BRODCASTING COMMUNICATION METHODS AND WAKEUP PERIOD

摘要

PURPOSE: A wireless network algorithm using a broadcasting communication method and a wakeup cycle is provided to make a wakeup cycle different, thereby preventing an echo signal due to broadcasting. CONSTITUTION: Each device is registered in a central controller. The central controller generates a different wakeup cycle. The central controller transmits the wakeup cycle to each device. Each device measures receiving sensitivity power by data of the central controller. Each device distinguishes a repeater from an end node. When a repeater can not operate due to failure or battery discharge, the device connects to another device with superior receiving sensitivity.
