Abstract

The invention provides a node dormancy method and system, terminal equipment and a computer readable storage medium. The node dormancy method comprises the steps of: calculating a current sensing areaof a node; judging whether the current sensing area of the node is completely covered by current sensing areas of other nodes in the network or not; and if the current sensing area of the node is completely covered by the current sensing areas of other nodes in the network, enabling the node to enter a dormant state. According to the node dormancy method of the invention, the redundant nodes in the network are analyzed according to the real-time sensing area of the nodes, and the redundant nodes enter the dormant state, so that the repetition amount of data acquisition can be reduced to the greatest extent, and the network survival time is prolonged.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a node dormancy method, a node dormancy system, a terminal device, and a computer-readable storage medium. Background technique [0002] In wireless sensor networks, sensor nodes are usually deployed in various environments to collect data. Due to the random distribution of nodes in the network, it is easy for nodes to be densely distributed in some areas, which is why there may be a large number of redundant nodes in the network. Too many redundant nodes will consume energy resources that are already very scarce and seriously reduce the survival time of the network. Therefore, how to identify whether a node is a redundant node in the network, and enter the dormant state in time when it is confirmed as a redundant node, so as to balance the energy in the network is an urgent problem to be solved at present. Contents of the invention [0003] The present d...
