The invention discloses a target-node-location-oriented dynamic sleep scheduling method in wireless sensor networks. The method comprises the steps of: creating a location tree, picking up wakeup anchor nodes and sleep anchor nodes from the location tree; then notifying the surrounding anchor nodes of the target node of a work mode, so that the target node can effectively keep high anchor node connectivity by dynamic sleep scheduling, location success rate and precision of the target node in wireless sensor networks is guaranteed. The massage passing mechanism is dispatching WAKEUP_MSG massage to anchor nodes in the wakeup nodes collection, to keep the wakeup state and enter a full-attendance working way; and dispatching PRUNE_MSG massage to anchor nodes in the sleep anchor nodes collection, to switch to sleep state and enter a low-consumption working way.

The invention discloses a device for monitoring and managing sleep quality and promoting sleep. The device comprises a hand monitoring unit and a pillow monitoring unit. The hand monitoring unit evaluates the specific sleeping condition of a monitored person and starts a corresponding preset hand perceptual mode by acquiring and analyzing the pulse information, the heart rate information, the motion information, the oxyhemoglobin saturation information, the regular exercise amount and the sleeping posture information of the monitored person, the temperature information of the environment where the monitored person is located, and the brightness information of the sleeping environment. The pillow monitoring unit acquires all the information of the monitored person, and starts a corresponding preset pillow vibration mode. The device has the advantages of being capable of promoting sleep, precise in data, safe, environment-friendly, multifunctional, small, portable and the like. The device can conduct multi-dimensional monitoring on multiple indexes like sleep quality, exercise amount and basal metabolic rate, can dynamically and intelligently conduct individualized guidance and management on sleeping plans according to sleeping parameters acquired through previous multi-dimensional monitoring, and can be applied to the normal sleep population, the insomnia population, the sleep apnea-syndrome population and the population with a snoring history but not diagnosed as sleep apnea-syndrome yet.

The invention discloses a coverage maintenance method based on sleep scheduling and coverage compensation. Specifically, the two methods of sleep scheduling and coverage compensation are adopted in the scheduling mechanism, thereby achieving the dual goals of efficient energy utilization and coverage maintenance. Firstly, the node judges whether it needs the surrounding neighbor nodes to move to it by estimating its own redundancy and remaining energy; the concept of absolute redundant node and relative redundant node is proposed for the first time; then the neighbor node judges whether it has the ability to move to the target The ability of location; by using the energy model for energy prediction to accurately judge the mobility of nodes, and then achieve the goal of maintaining coverage, and then adopt a sleep scheduling mechanism to avoid the waste of redundant node energy and achieve high-efficiency energy utilization The goal.
