Embodiment Construction

[0047] Various preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0048] The system and method of the present invention combine distributed and centralized routing ideas, and the general idea of ​​the scheme is as follows: first, let the wireless mesh network access point (hereinafter referred to as MAP) in the wireless mesh network (hereinafter referred to as Mesh) network Run a general distance vector routing protocol, such as RIPv2 protocol, to complete the establishment of backbone routing and network topology; secondly, select one of the MAPs to act as a location query server for wireless mobile nodes (hereinafter referred to as STAs), and collect all STAs in the Mesh network and the information they belong to The corresponding relationship of MAP; Next, when the STA needs to send data, it queries the location query server for the MAP of the destination STA through its MAP, and then implements r...

Abstract

The wireless mesh network includes multiple wireless mobile nodes and network access points of wireless mesh network. The method includes following steps: running route protocol of distance and vector at each network access point of wireless mesh network so as to establish backbone route and network topology; selecting one network access point of wireless mesh network as sever for querying location for all wireless mobile nodes; collecting coincidence relations between all wireless mobile nodes in wireless mesh network and their network access points of wireless mesh network; when any one of wireless mobile node needs to send data, using its access point through the sever for querying location queries access point of destination wireless mobile node in wireless mesh network. Combining idea of centralized route with idea of distributed route, the invention enhances expandability protocol of mesh network.

Description

technical field [0001] The invention relates to a method for updating the position of a network mobile node, in particular to a method for updating the position of a network mobile node in a wireless mesh network. [0002] The invention also relates to a system for updating the position of the network mobile node in the wireless mesh network. Background technique [0003] The development of wireless network technology is changing with each passing day. Various 802.11x standards are constantly being updated, and new wireless network architectures and technologies are constantly being proposed. At present, a new wireless mesh network - wireless Mesh network appears. The wireless mesh network Mesh network is also called "multi-hop" network, which is a new wireless network technology completely different from the traditional wireless network. In a traditional wireless local area network, each client accesses the network through a wireless link connected to the wireless local ar...
