Embodiment Construction

[0052] The channel allocation method and device for supporting multiple services in a Mesh network according to the present invention will be described in detail below with reference to the accompanying drawings.

[0053] The invention improves the IEEE 802.11s, and proposes a channel allocation and connection establishment method suitable for the mesh network that supports multiple services and can guarantee service quality. The characteristics of this method are: the source node informs the node receiving the connection of the channel usage of its surrounding nodes through the connection request packet, and the destination node uses the TCH usage of the nodes around the node and the TCH usage in the connection request packet for this connection. Select an available TCH, and inform the source node through a response frame, and then both the source node and the destination node should choose whether to send a preemption frame according to the current usage of the TCH selected f...

Abstract

The method comprises: a) source node sends a connection request packet to the destination node, which comprises the information about channel service condition of said source node and its neighboringnodes; b) according to the channel service condition, the destination node selects a available transmission channel, and uses a response message to inform the source node; c) according to the currentservice condition of the available transmission channel, the source node and destination node decide if an occupation message needs to be sent; the source node sends out a confirmation message; d) according to the occupation message and confirmation message, establishing channel connection and allocation.

Description

technical field [0001] The present invention relates to the field of communication, more specifically, to a method and device for channel allocation and connection establishment of a Mesh (mesh) network. Background technique [0002] The invention relates to the technology in the Mesh network, in particular to the wireless mesh network, that is, the technology in the Mesh network that supports multiple services and guarantees service quality. [0003] The wireless mesh network is a new generation of wireless network architecture proposed by Intel and other manufacturers. A traditional wireless network must first visit a centralized access point (AP: AccessPoint) to perform wireless connection. In this way, even if two nodes are physically next to each other, they must pass through the access point to communicate. In a wireless Mesh network, each node can communicate directly with one or more peer nodes. [0004] Wireless Mesh network is a multi-hop wireless network, which...
