Method for changing center node of star-type ad hoc network

Abstract

The invention proposes a method for changing a center node of a star-type ad hoc network. The method comprises the following steps: access nodes carry out measurement based on a center node and reportmeasurement information to the central node periodically, wherein the measurement information includes signal strength and quality information; the center node determines whether to start center nodeselection according to the number of access nodes connected to the network currently as well as a network topology change frequency; and if so, calculation is carried out based on the measurement information of all access nodes to select a new center node; and according to the new center node, whether center node changing is carried out is determined. According to the invention, because of adaptive selection of a proper node as a new center node, a problem of performance degrading after continuous changing of the topological structure of a star-type ad hoc network is solved, so that the robustness of the bottom network of the universal network is improved.

Description

technical field [0001] The invention relates to the technical field of ecological circle wireless communication, in particular to a method for changing a central node of a star self-organizing network. Background technique [0002] The star wireless ad hoc network in the wireless environment is a wireless ad hoc network with a relatively simple network structure and easy implementation. After the completion of the network deployment, as the nodes continue to move, the network topology between the nodes is constantly changing. The original central node may no longer be suitable as the central node. If the central node cannot be changed in time and automatically selects a more suitable node as the If there is no new central node, the performance of the entire wireless star self-organizing network will be greatly affected. The current related technologies cannot adaptively elect more suitable nodes, resulting in performance degradation after the topological structure of the st...

After the completion of the network deployment, as the nodes continue to move, the network topology between the nodes is constantly changing. The original central node may no longer be suitable as the central node. If the central node cannot be changed in time and automatically selects a more suitable node as the new central node, the performance of the entire wireless star self-organizing network will be greatly affected

The current related technologies cannot adaptively elect more suitable nodes, resulting in performance degradation after star self-organizing network topology changes continuously
