The embodiment of the invention provides an ad hoc network communication method and device, electronic equipment and a medium, and relates to the technical field of communication, and the method comprises the steps: sending a network access request to a main node in a public time slot segment of any communication period, the communication period comprising a synchronous time slot segment, the public time slot segment and a private exclusive time slot segment; monitoring a first synchronization frame sent by the main node in a synchronization time slot segment of a communication period after the communication period; analyzing the first synchronization frame; and if the first synchronization frame comprises indication information of a private exclusive time slot segment of a slave node, sending data in the private exclusive time slot segment specified by the indication information in the communication period in which the first synchronization frame is located. According to the method, the communication quality can be improved.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to an ad hoc network communication method, device, electronic equipment and medium. Background technique [0002] At present, more and more intelligent devices have entered people's daily life, for example, many intelligent robots are installed in places such as restaurants, shopping malls and museums. If there are multiple smart devices in a scene, it is necessary to ensure the multi-machine coordination of the multiple smart devices in the scene, such as global obstacle avoidance and global path planning. [0003] In order to ensure the multi-machine coordination of multiple smart devices in a scene, it is necessary to maintain good communication between smart devices, or to maintain good communication between smart devices and a server. [0004] In the prior art, communication between smart devices and between smart devices and servers can be performed on a f...
