Embodiment 1

[0045] Such as figure 1 As shown, an ad hoc network time synchronization method provided in an embodiment of the present invention includes:

[0046] S1. Obtain the node with the highest phase in the cluster as the cluster head node, and perform time synchronization between the cluster head node and the cluster head nodes of other clusters, and the other nodes of the cluster are used as intra-cluster nodes and enter a dormant state;

[0047] S2, the nodes in the cluster in the dormant state stop dormancy, and perform time synchronization with the cluster head node of the cluster.

[0048]In the self-organizing network time synchronization method described in the embodiment of the present invention, in the inter-cluster synchronization stage, the node with the highest phase in the cluster is obtained as the cluster head node, and the cluster head node is timed with other cluster head nodes in other clusters. Synchronization, the other nodes in the cluster are in the dormant st...

Abstract

The invention provides a method and a device for self-organization network time synchronization and can improve the system convergence speed and reduce a system load. The method comprises steps that a node having the highest phase in a cluster is taken as a cluster head node, time synchronization of the cluster head node and cluster head nodes of other clusters is carried out, and other nodes of the cluster are taken as in-cluster nodes which enter into a dormant state; the in-cluster nodes in the dormant state stop dormancy and realize time synchronization with the cluster head node of the cluster. The device comprises an inter-cluster synchronization module used for acquiring the node having the highest phase in the cluster and taking the node as the cluster head node and an in-cluster synchronization module used for making the in-cluster nodes in the dormant state stop dormancy and realizing time synchronization of the in-cluster nodes and the cluster head node of the cluster, wherein time synchronization of the cluster head node and the cluster head nodes of other clusters is carried out, and the other nodes of the cluster are taken as the in-cluster nodes which enter into the dormant state. The method is suitable for the network technology field.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method and device for time synchronization of an ad hoc network. Background technique [0002] Self-organizing network is an important way to realize flexible deployment, efficient operation and maintenance, reliable service and collaborative optimization of heterogeneous converged network. Self-organizing network is a temporary network that can be quickly established without relying on the preset infrastructure. Network nodes use their own wireless transceiver equipment to exchange information in a distributed control mode, and can achieve multi-hop communication with the help of intermediate node relays. Therefore, Also known as a multi-hop network. Due to the characteristics of self-organization, no center, and multi-hop, the wireless ad hoc network has the advantages of convenient networking and strong invulnerability, so it has attracted extensive attention. [0003] Al...
