Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0025] Such as figure 1 As shown, it is a system diagram of a Mesh network, and the Mesh network includes a master node 11 and slave nodes 12-14. Both the master node 11 and the slave nodes 12-14 can perform wireless data forwarding, and can be connected to an external network (External Network), such as the Internet, through a multi-hop wireless link. In addition, the Mesh network may also include user terminal equipment with a wireless forwarding function, such as various mobile devices such as mobile phones and mobile computers.

[0026] Each frame in the Mesh network includes static time domain resources and dynamic time domain resources, and the static time domain resources of each frame are fixedly allo...

Abstract

The invention discloses a resource scheduling method in a Mesh network. The Mesh network comprises a master node and a plurality of slave nodes. The method comprises the following steps that the master node acquires service demand information of the master node and the slave nodes; the master node allocates time domain resources to the plurality of slave nodes according to the service demand information; and the master node sends time domain resource allocation information of each slave node to the corresponding slave node respectively, so that each slave node determines the time domain resources which are obtained by allocation respectively and carries out frequency domain resource allocation on the respective time domain resources. The invention further discloses a corresponding Mesh network node and the resource scheduling method in the Mesh network. According to the resource scheduling method in Mesh network and the Mesh network node, a problem of overlarge network load of the master node is effectively solved, and the stability of network performance is improved.

Description

technical field [0001] The invention relates to the technical field of Mesh network communication, in particular to a resource scheduling method in a Mesh network and a Mesh network node. Background technique [0002] Centralized scheduling is a resource scheduling method commonly used in Mesh (mesh network) networks. Usually, all nodes report the business requirements to the master node, and the master node allocates available network resources to each node according to a certain algorithm, and specifies the transmission parameters of each node, such as modulation and coding methods, etc. It can be seen that, In this method, the master node is required to maintain a large amount of information of the nodes in the whole network, such as the channel quality between nodes, etc. When the network scale is large, the load of the master node is large, which is likely to become the bottleneck of network performance, and the signaling overhead required for each node to report its o...
