Embodiment Construction

[0068] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0069] The present invention proposes a routing method and device suitable for such a network and capable of providing quality of service guarantees for a k-hop clustered Mesh network, which is referred to herein as QCBR (QoS-constraint Cluster-Based Routing)——QoS Constrained clustering routing protocol.

[0070] The main idea of ​​QCBR according to the present invention is to adopt the method of resource reservation, at first find the path that meets the bandwidth requirement for the real-time business flow in Mesh network, carry out resource reservation on this route (that is, stay to transmit data in the future), In this way, a method and device for finding a path satisfying the bandwidth requirement from the source node to the destination node are provided for the k-hop clustered Mesh network.

[0071] According to above-mentioned thought, the present inven...

Abstract

This invention provides a network routing method used in providing optimum route for transmitting service flows between a source node and a destination note including: a, responding to a global routing request sent by the source note to find out at least one route meeting the request of bandwidth for transmitting service flows with the destination node, b, selecting a route with the optimum delay and stability in at least one route as the optimum route and c, preserving resources for the optimum route for transmitting service flows. This invention also provides a network routing device.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a Mesh network routing method and device. Background technique [0002] Wireless Mesh Network, also known as Wireless Mesh Network, is a broadband wireless access technology developed on the basis of Wireless Local Area Networks (WLAN: Wireless Local Area Networks), but unlike WLAN, the entire Mesh network includes access The plane and the transmission plane are divided into two parts. The access plane is composed of a single Mesh router and multiple mobile terminals, and the mobile terminal accesses the Mesh network through the Mesh router connected to itself. The transmission plane is a multi-hop wireless network formed by interconnecting multiple Mesh routers. The Mesh router can simultaneously integrate the function of AP (Access Point, wireless access point) to provide broadband wireless access for mobile terminals. The wireless Mesh network has the characteristi...
