Abstract

The invention discloses an efficient routing method of a high rate-wireless personal area network (HR-WPAN) mesh network and relates to routing technology based on topology servers in the WPAN mesh network. According to the routing method, broadcasting Link State Registration information, converging the Link State Registration information, shortening the length of relay node lists, releasing optimal path information through self-adaptive routing and a routing mechanism based on node dump energy are adopted, and the problems that the unicast control information of an existing routing method of the WPAN Mesh network based on the topology servers can not release network topology information sufficiently, the number, the content and the forwarding path of the control information are redundant, node energy is not considered in a routing process under the multi-path conditions and the like are solved. Control overload is reduced, path constructing time is shortened, node energy consumption is balanced, network bandwidth is saved, the efficiency of the routing method and the performance including time delay and the like are improved, and service life of the network is prolonged.

Description

technical field

[0001] The present invention relates to WPAN Mesh network (Wireless Personal Area Networks Mesh) technology, in particular to a high-speed wireless personal area network that adopts a routing technology based on a topology server and assigns an independent identifier to each node in the network. Network HR-WPAN Mesh network (High Rate Wireless Personal Area Networks Mesh). Background technique

[0002] WPAN Mesh network refers to a mesh wireless communication network composed of WPAN devices (portable electronic products and communication devices). The WPAN Mesh network has the following advantages: it can expand the coverage of the network without increasing the transmission power or improving the receiving sensitivity; it can increase the reliability of data transmission through redundant routes; it can simplify the configuration of network nodes; and extend the life of nodes. According to different application scenarios, WPAN Mesh networks can be divided ...
