Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0031] The auxiliary time reference bootstrapping method based on the high-precision time synchronization self-organizing network designed and realized by the present invention is implemented in a distributed manner. Each node independently performs auxiliary time reference judgment processing according to its topological position in the network, maintains the entire network topology, and ensures high-precision time synchronization of the entire network. The flow chart of the method provided by the present invention is as follows figure 1 shown. Its characteristics include the following steps:

[0032] At the beginning of the establishment of a high-precision time synchronization network, first, a node with high time accuracy and a relatively fixed location is designated ...

Abstract

The invention provides an auxiliary time benchmark bootstrapping method based on a high-precision time synchronization self-organizing network. A time benchmark provides a time reference, and a node to have access to the network finishes the access process; access nodes build neighbor report chain tables of the access nodes, all the nodes in the network obtain information of neighbors of the nodes according to the neighbor report information, the nodes judge whether to serve as the time reference to assist the time benchmark in sending access information periodically according to the network levels of the nodes and the network levels of all the neighbors, and the nodes and the node to have access to the network carry out access and timing. It is guaranteed that the nodes have access to the network to the greatest extent, a processing method is simple and easy to implement, node flow processing has consistency, manual planning and intervention are not needed, and the dynamic self-organizing capacity of the network is reflected sufficiently.

Description

technical field [0001] The invention relates to the networking technology of the self-organizing network, in particular to an auxiliary time reference bootstrapping method of the self-organizing network which needs to realize the high-precision time synchronization of the whole network. Background technique [0002] Ad hoc network is a mobile, multi-hop, autonomous system, its main features are: [0003] 1) Independent networking: the organization of the network does not need to rely on any planning and prior information, and the nodes can quickly and automatically form an independent network after they are turned on. [0004] 2) Dynamic topology: that is, nodes in the network can be moved and closed arbitrarily, and the topology of the network changes dynamically. Nodes can join or leave the network at any time, and the failure of any node will not affect the operation of the entire network. It is a peer-to-peer network with no central structure and strong invulnerability....
