A Method for Synchronizing the Topology of Non-Central Self-Organizing Networks

Abstract

The invention discloses a method for synchronizing a non-center self-organizing network topology, comprising the following steps: after a node device acquires local wireless connection information, a topology entry of the node device is generated, and when a change in the topology connection is detected, the entry is forwarded To the adjacent node, the adjacent node processes the forwarding entry after receiving it, and forwards it to its adjacent node. The topology entries of all nodes are combined into the topology information table of the entire network to complete the network topology synchronization of the entire network. After the synchronization is completed, the transmission route between any nodes can be calculated through the topology information table of the entire network, and no additional routing information transmission is required, which reduces the load of the network communication channel. In this method, only when a node detects a change in the connection state, it will spread its own topology connection information outward, and through the update identification and signature measures attached to the information, the invalid transmission of messages in the network is reduced, and the topology information is guaranteed. timely, effective and reliable.

Description

technical field [0001] The invention relates to networking and management of a wireless communication transmission network, in particular to a synchronization method for a centerless ad hoc network topology. Background technique [0002] For a self-organizing network without a center, nodes have complete autonomy and equal status, there is no central control entity in the network, and the network topology formed by wireless channels between nodes may change at any time, and the way and speed of the change are different. It is unpredictable, and maintaining these dynamically changing topology information requires a large number of control messages, and the larger the network scale, the greater the network maintenance and management overhead. Especially for those non-central self-organizing networks (such as meteor trail communication system) with characteristics of narrow channel bandwidth, low transmission rate, and random burst, they are more sensitive to network management...

[0002] For a self-organizing network without a center, nodes have complete autonomy and equal status, there is no central control entity in the network, and the network topology formed by wireless channels between nodes may change at any time, and the way and speed of the change are different. It is unpredictable, maintaining these dynamically changing topology information requires a large number of control messages, and the larger the network scale, the greater the overhead of network maintenance and management

Especially for those non-central self-organizing networks (such as meteor trail communication system) with characteristics of narrow channel bandwidth, low transmission rate, and random burst, they are more sensitive to network management overhead, and the maintenance of topology information is more difficult. difficulty
