Group range finding method based on a wireless dynamic self-organizing network

Abstract

The invention relates to the technical field of radio range finding and particularly to a group range finding method based on a wireless dynamic self-organizing network, wherein the method simultaneously measures distances from one member to multiple other members in the wireless self-organizing network by radio waves. The method ensures range finding precision by roundtrip range finding, and also optimizes a response process. After a member sends a message, other members in the network respond simultaneously after receiving the message. Meanwhile, reception channels of a receiver are increased to ensure the member who initiates the range finding can simultaneously receive range finding messages from other network members. Compared with the prior art, the method has the following beneficial effects that multiple feedbacks can be received at one time such that distances from one member end machine to multiple member end machines can be measured simultaneously, and thus the method is better than a roundtrip time calibration range finding method based on time division. The method may respond immediately, and is obviously better than a range finding method based on network clock synchronization, and the method can perform range finding immediately.

Description

technical field [0001] The invention belongs to the technical field of radio distance measurement, and in particular relates to a group distance measurement method based on a wireless dynamic self-organizing network, which utilizes radio waves to simultaneously measure the distance between a member and multiple other members in a wireless self-organizing network . Background technique [0002] In the field of wireless dynamic ad hoc networks, it is an important practical application requirement to measure the distance between a member and other members in the group with as few network resources as possible in the shortest possible time, and the key to solving this problem is An efficient wireless network group ranging method is designed. [0003] There are two commonly used methods for realizing ranging between members in a wireless network: the ranging method based on network clock synchronization and the round-trip timing ranging method based on time division.

Problems solved by technology

[0017] The technical problem to be solved by the present invention is: because the ranging method based on network clock synchronization in the prior art has short ranging time but poor ranging accuracy, the time-division-based round-trip timing ranging method has higher ranging accuracy but group The group ranging time is long, so how to provide a wireless group ranging method with short ranging time, high ranging accuracy and simultaneous measurement of the distance between multiple network members
