Star network multi-center node merging method

Abstract

The invention discloses a star network multi-center node merging method, which comprises the following steps: S1, after star network networking is completed, each access node of a network reports respective measurement and report information; S2, a network monitoring task is started as a sentry role node; S3, a central node judges whether network merging needs to be initiated or not according to a monitoring result reported by the sentry role node; S4, if the central node judges that the combination of the network to an external network needs to be initiated, the work of all sentry role nodes is stopped, and a network change notification message is issued; and each access node initiates a network search and access process according to the external network information carried in the received network change notification message. According to the invention, the center nodes of a plurality of star networks can be merged, and a star network with a unique center node is reconstructed, so that a plurality of small-scale star ad hoc networks are automatically fused into a large-scale self-organizing star network.

Description

technical field [0001] The invention relates to a star network multi-center node, in particular to a star network multi-center node merging method. Background technique [0002] At present, the star network is one of the organizational forms of the wireless ad hoc network topology. There is a central node and several access nodes connected to the central node in the star network. All access nodes and central nodes together form a star network. [0003] There are two scenario problems in the self-organizing star network, and the method of network merging needs to be considered. For wireless ad-hoc star network, there is a certain randomness in the selection of the central node of the star network each time the network is formed, which may lead to the situation that multiple central nodes form a small network at the same time. In this undesired scenario, further network consolidation is required to implement a star network. For different star networks that have been networ...

Problems solved by technology

[0005] A network with a fixed central node role, when there are multiple networks, it is difficult to merge

Even if the respective networks are broken up and reorganized, there is still the problem that the central node with a fixed role is difficult to choose and access the network

In this process, the manual participation of the operator is indispensable.
