Embodiment Construction

[0039] Changes in water quality data in intensive aquaculture waters, tracking of aquaculture aquatic products, and water environmental pollution constitute specific aquaculture environmental events. The present invention proposes a method for clustering sensing nodes based on event-driven low-power consumption. The method is oriented to the intensive aquaculture Internet of Things, which can reduce the energy loss of sensing nodes, shorten the average transmission delay of data messages, and improve It improves the perceived reliability of specific farming environmental events.

[0040] In the present invention, two working states of sensing nodes of the intensive aquaculture Internet of Things are defined: constant state and event state.

[0041] 1) Invariant state: that is, when no breeding environment event occurs.

[0042] In this state, in order to reduce energy consumption, the sensing node enters a low-power cycle of periodic sleep / wake-up.

[0043] 2) Event status: ...

Abstract

The invention relates to a low power consumption medium access control method of intensive aquaculture Internet of Things, and provides an event-driven low power consumption perception node clustering method. The method is oriented to the intensive aquaculture Internet of Things, and can reduce energy loss of perception nodes. The event-driven low power consumption perception node clustering method is oriented to the intensive aquaculture Internet of Things, can reduce the energy loss of the perception nodes, shortens average transmission delay of a data message, and improve the perception reliability of specific culture environment events.

Description

technical field [0001] The invention belongs to a medium access control method for the aquaculture Internet of Things, and in particular to a medium access control method for an intensive aquaculture Internet of Things with low power consumption. Background technique [0002] The intensive aquaculture Internet of Things is composed of a certain number of wireless sensing nodes that monitor different aquaculture environment data and have limited energy storage. Based on the traditional wireless sensor network (WSN) medium access control (MAC) method, all sensing nodes will directly send information to the sink node, and the energy consumption of each node is large, which shortens the network survival time; because the sink node is forced to receive a large number of Redundant information causes frequent message collisions, increased transmission delay, and serious message loss. [0003] The medium access control (MAC) layer of the intensive aquaculture IoT is implemented by ...
