Method for realizing wireless personal area network routing protocol based on ultra-wide band positioning assist

Abstract

The invention relates to a method for realizing wireless personal area network routing protocols based on ultra-wide band positioning assist, comprising the following steps of: firstly acquiring the coordinate of each node in a network by utilizing an ultra-wide band positioning technique, then carrying out flooding routing discovery with a limited range by using the nodes based on positioning information, updating routing request areas by utilizing the middle node receiving a routing querying message according to the recording position information of the node, and then selecting fan-shaped areas with dynamically regulated ranges in the routing request areas. The simulated and analyzed results show that compared with LAR (Location-Aided Routing) protocols, after carrying out node positioning with low node energy consumption and calculation and updating on the routing request areas, the invention reduces the overheads of routing control messages, shortens the end-to-end average time delay of data messages, and obviously improves effects.

Description

technical field [0001] The invention is a routing technology based on ultra-wideband positioning assistance in wireless personal area networks, which is suitable for the application of wireless personal area networks providing high-quality multimedia services, belongs to the field of wireless communication technology, and is specifically a wireless network based on ultra-wideband positioning assistance. Implementation method of personal area network routing protocol. Background technique [0002] Wireless Personal Area Network (WPAN) is a wireless network formed in the surrounding space of the individual. It usually refers to a short-distance wireless network with a coverage range within a radius of 10m, especially a short-distance special connection between portable consumer appliances and communication equipment. self-organizing network. WPAN is positioned as a short-distance wireless communication technology, but it is divided into high-speed WPAN (HR-WPAN) and low-speed...

Problems solved by technology

[0010] The problem to be solved by the present invention is: when the wireless network utilizes the request area to perform routing query, the existing LAR protocol way route can not update the route request area in time because the request area is greatly affected by the relative position of the source node and the destination node, and there is route discovery In case of failure, the adjustment of the routing request area is too simple. To solve these problems, an ultra-broadband location-assisted routing protocol with dynamic adjustment of the routing request area is proposed.
