Remote node sleep state machine control method and system based on message timing analysis

Abstract

The application discloses a remote node sleep state machine control method and system based on message timing analysis, relates to the field of node power consumption management control, and comprises the following steps: obtaining the arrival time stamp and message identifier of an inbound message and storing the message according to service categories; extracting statistical features based on adjacent arrival time interval sequences of messages of various categories, constructing a message arrival probability distribution model and calculating an arrival risk function; combining service priorities to obtain a system-level comprehensive risk function through weighted fusion, and predicting an expected time of arrival of a next message; and calculating a safety margin in combination with a current energy state of a node, and selecting a target sleep state in a multi-level sleep state machine. Thus, dynamic control of sleep depth and wake-up timing is realized, and the adaptability and response coordination of low-power consumption management of a remote node are improved.
