Abstract

The invention discloses a wireless ad hoc network neighbor node discovery method for a power construction site. Static edge nodes, static non-edge nodes and dynamic nodes are defined according to deployment positions; the static edge node and the non-edge node initialize an adjacent node table according to the deployment position; each node calculates the scanning probability of each beam direction according to the scanning coefficient, and selects the beam direction according to the scanning probability to execute neighbor node discovery; and the dynamic node detects whether a static edge node is found in each beam direction at a certain frequency, if so, further detects whether an adjacent node table in an adjacent 90-degree range on two sides of the dynamic node is empty, and if so, reduces the scanning coefficient in the beam direction in the 90-degree range and increases the scanning coefficient in the 180-degree symmetrical beam direction. The method has the advantages that through identity definition and edge detection of the node, limited energy of the node is concentrated in a wave beam direction which is more likely to be non-edge to execute neighbor node discovery, so that the energy consumption of the node is reduced, and the discovery efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for discovering neighboring nodes of a wireless self-organizing network at a power construction site. Background technique [0002] Electric power construction is often located in remote areas, and often faces the problem of no signal for mobile communications based on traditional cellular networks. In addition, due to the large coverage of power construction sites, commonly used communication methods such as WIFI and optical fiber are not widely used due to reasons such as coverage, communication quality, and construction costs. [0003] The wireless ad hoc network nodes based on switchable beam antennas can concentrate energy in a specific direction through the transmission and reception of directional beams, thereby providing long-distance, low-latency, stable and reliable information transmission. For electric power construction sites, various types o...
