Method for controlling emission power of mesh network node and mesh network node

Abstract

The invention relates to communication technology, especially the meshy network communication technology, the invention discloses a control meshy network node emission power method and meshy network node. The technique scheme is based on the integral performance of network, according to the performance requirement of different operations, combining the topology structure of network to adjust power, so the purpose of optimizing network performance can be achieved; it resolves problems that current technology can not based on the performance requirement of different operations, combining the topology structure of network to adjust emission power; it further combines point to point power control method between current nodes, the emission node builds power table to record current emission power of every adjacent node, and resolves problems that current power control information mutual continually and occupy resource of system.

Description

technical field [0001] The invention relates to communication technology, in particular to mesh network communication technology, and discloses a method for controlling the transmission power of mesh network nodes and the mesh network nodes. Background technique [0002] The nodes in the Mesh Network are connected to one or more nodes, and the nodes only communicate directly with neighboring nodes (one-hop communication), so the communication between two non-adjacent nodes needs to be transferred through other nodes (multi-hop communication). Because each node may have multiple connections, there may be multiple communication paths between two nodes, which can improve the reliability of the entire network system. Personal Area Network (PAN, Personal Area Network): refers to the network composed of devices within the personal range, and the personal range also refers to the range of short distances. Corresponding concepts. Devices in the PAN can be connected through variou...

Problems solved by technology

[0012] The present invention provides a method for controlling the transmission power of a mesh network node and a mesh network node, so as to solve the problem in the prior art that the transmission power cannot be reasonably adjusted according to the performance requirements of different services and in combination with the network topology;

[0013] Further combining the existing point-to-point power control method between nodes, the transmitting node establishes a power table to record the current transmitting power of each neighbor node, and further solves the problem that the existing power control information frequently occupies system resources
