AI Technical Summary

Technical Problem

In robot networks, beacon collisions are frequent during neighbor discovery. Existing methods struggle to effectively adjust slot lengths and backoff windows, leading to increased discovery latency and failing to meet the demands of rapid topology changes.

Method used

This paper presents a neighbor discovery conflict coordination method for robot networks. By adaptively adjusting the time slot length and backoff window, it estimates the network state using the number of beacon receptions and conflict information, and combines a cross-layer beacon conflict coordination mechanism to quickly respond to beacon conflicts.

Benefits of technology

It enables rapid discovery between nodes in the event of beacon collisions, reduces discovery latency, and improves the efficiency and flexibility of neighbor discovery, making it suitable for various distributed wireless networks.

Abstract

The application discloses a kind of methods, equipment and medium for robot network-oriented neighbor discovery conflict coordination, it is related to communication technical field, method includes: initialization reference parameter and according to reference parameter, channel is listened to and conflict is detected, to update beacon quantity, beacon receiving list and conflict mark bit;According to conflict mark bit, identify conflict, when no conflict is identified, re-initialization reference parameter and according to reference parameter, channel is listened to and conflict is detected, to update beacon quantity, beacon receiving list and conflict mark bit, when conflict is identified, according to beacon quantity, conflict mark bit, preset time slot adjustment step, preset backoff window coefficient adjusts time slot length and backoff time, again according to backoff time, channel is listened to to update beacon receiving list;According to beacon receiving list, backoff time and preset beacon duration, the working state of robot is controlled.The application can adjust time slot length and backoff window according to network state and carry out conflict coordination adaptively.
