HR-WPAN Mesh (high-rate wireless personal area networks mesh) network efficient route repair method based on self-adaptation two-way path rebuilding

Abstract

The invention provides an HR-WPAN Mesh (high-rate wireless personal area networks mesh) network efficient route repair method based on self-adaptation two-way path rebuilding. Through adopting four new mechanisms of self-adaptation two-way path re-building, Route Error message simplification, Route Formation message simplification and inter-layer auditing, the method solves the four problems that the existing HR-WPAN Mesh network route repair method based on a topology server adopts a reverse path rebuilding mode, so that the redundancy control expenditure and data grouping waiting delay are caused, when the end points of two damaged paths are mutually used as source and target nodes, the path rebuilding is repeatedly carried out, and when the Route Error message and the Route Formation message have redundancy fields and link failure, data groups cached by the upstream node can be easily lost due to route information limitation. The method has the advantages that the speed of putting the repaired route into use is accelerated, the data grouping transmission success rate is improved, and the control expenditure and the data grouping average time delay are reduced. The fast and efficient route repair method provided by the invention comprises three steps including fault reporting, path building notification and path rebuilding during the operation.

Description

technical field [0001] The invention belongs to the technical field of WPAN Mesh (Wireless Personal Area Networks Mesh, wireless personal area mesh network) network, and particularly relates to a route repair method and process of a HR (High Rate, high rate)-WPAN Mesh network routing scheme. Background technique [0002] WPAN Mesh network is a distributed multi-hop mesh wireless network formed by electronic communication equipment carrying short-distance wireless communication devices in a self-organizing manner. The WPAN Mesh network can expand the coverage of the network without increasing the transmission power of the nodes and improving the receiving sensitivity, and can increase the reliability of data transmission through routing redundancy; the configuration of the WPAN Mesh network is relatively simple, which helps to save the energy of the nodes Thereby prolonging the life of the network. According to different data transmission rates, WPAN Mesh networks can be rou...
