Problems solved by technology

[0003] In the prior art, since each node adopts a power control strategy to control its own transmission power, and each node has mobility, the connection status between certain two nodes may affect the integrity of the network
That is to say, if the connection between the two nodes is broken, a complete network will be split into two subnets, and the nodes between the two subnets cannot communicate with each other, destroying the integrity of the network

Abstract

The embodiment of the invention discloses a node power control method, device, equipment and storage medium. The method includes: in the node network where it is located, detecting whether there is a key neighboring node forming a critical path with the current node; wherein, when the critical path is disconnected, the node network can be divided into two independent subnets; If yes, set the sending power of the current node to be greater than or equal to the power threshold matching the critical path. The technical solutions of the embodiments of the present invention enable nodes to identify critical paths in the network, and ensure the connection status of the critical paths through power control strategies, reduce the probability of the network splitting into multiple subnets, and ensure the integrity of the network.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a node power control method, device, device, and storage medium. Background technique [0002] In a mobile ad-hoc network, each node can control the actual transmission power through the traffic volume and air interface transmission capacity, instead of always using a fixed maximum transmission power, so as to achieve better spatial multiplexing and reduce energy consumption of nodes. Extend the life of your mobile network. [0003] In the prior art, since each node adopts a power control strategy to control its own transmission power, and each node has mobility, the connection state between certain two nodes may affect the integrity of the network. That is to say, if the connection between the two nodes is broken, a complete network will be split into two subnets, and the nodes between the two subnets cannot communicate with each other, destr...
