Embodiment Construction

[0052] The research focus of the present invention is how to reasonably allocate a minimum set of network monitoring agents. The present invention aims at the characteristics that the Mesh wireless network structure changes from time to time, and proposes a network monitoring method that utilizes a monitoring agent allocation method based on resident weights. The present invention has the following characteristics:

[0053] 1) Introduce the node resident trust mechanism to avoid the overhead caused by frequent replacement of proxy nodes;

[0054] 2) The performance is good, and its time complexity will not increase exponentially with the expansion of the network scale;

[0055] 3) Adopt new routing criteria, avoid computing network bandwidth, and consider interference that may be the bottleneck of the entire transmission, so it is more suitable for the real world.

[0056] The invention introduces the concept of node resident weight, optimizes the set of monitoring agent node...

Abstract

The invention discloses a realization method for a wireless mesh network and nodes. The realization method for the wireless mesh network comprises steps: obtaining nodes and route information needing to be monitored in the network, according to the associated relationship between the nodes and the route, obtaining a monitoring acting candidate set in the network which covers maximal link and has minimum nodes, selecting a node set with larger residing weighted value of the nodes from the acting candidate set as a monitoring agency; adopting the selected agency to monitor the routing transmission of the wireless mesh network, wherein the anticipated transmission time SMETT of the route is measured in the transmission process, thus forming the route measuring result; and according to the result, controlling packet routing or call forwarding. The invention can increase network performance and reduce resource consumption.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless mesh network (WMN, wireless Mesh Network). Background technique [0002] Wireless Mesh network is a wireless broadband access technology based on IP protocol. It combines the advantages of wireless local area network (WLAN, Wireless LAN) and Adhoc network, supports multi-point to multi-point mesh structure, and has self-organizing, self-repairing, Intelligent advantages such as multi-hop cascading, node self-management, mobile broadband, wireless positioning, etc., are a large-capacity, high-speed, and wide-coverage network that has become an effective means of broadband access. In a sense, the Mesh network is mainly a kind of network architecture idea, and its main functions are reflected in the centerless, self-organizing network, multi-level jumping and routing judgment selection. [0003] In a network built with Mesh technology, its topological structure is grid-like, wi...
