Problems solved by technology

[0004] The existing initial network construction scheme of the ad hoc network has the following disadvantages: the central node (that is, the PAN coordinator) cannot obtain the communication status between adjacent nodes in the network, so it cannot quickly obtain routing information. When a problem occurs, the PAN coordinator cannot detect it in time, resulting in inflexible communication within the network

Embodiment Construction

[0033] As mentioned in the background art, in the ad hoc network system in the prior art, when a node in the network has a problem, the ad hoc network cannot respond flexibly.

[0034]In the Zigbee network, only the coordinator (coordinator) device can establish a network, and in the process of establishing a network, all implementation processes are realized through primitives. See figure 1 , figure 1 A schematic diagram of a new Zigbee network in the prior art is provided.

[0035] First, the coordinator device invokes a network construction request (that is, the NLME_NETWORK_FORMATION.Request primitive shown in the figure) at the Zigbee coordinator application layer (hereinafter referred to as the application layer), and the Zigbee coordinator network layer (hereinafter referred to as the network layer) receives this original In other words, the Zigbee coordinator media access control (Media Access Control, MAC for short) layer (hereinafter referred to as the MAC layer) i...

Abstract

The invention discloses a network access method and device of an ad hoc network, computer equipment and a storage medium. The ad hoc network comprises a plurality of nodes, wherein at least one node is a PAN coordinator. The network access method comprises the steps of detecting whether a synchronization preamble sent by any node in the ad hoc network is received or not, and if the synchronizationpreamble sent by any node in the ad hoc network is received, realizing time and frequency domain synchronization according to the synchronization preamble and the node sending the synchronization preamble; when a networking notification of the ad hoc network is received, sending a network access request to a node sending the networking notification, wherein the network access request is sent to the PAN coordinator, and the PAN coordinator judges whether to agree with the network access request or not; if the PAN coordinator agrees with the network access request, receiving a network access notification, wherein the network access notification is sent by the PAN coordinator; and communicating with other nodes in the network according to a communication rule of the ad hoc network. In the method, the PAN coordinator collects information of network access nodes when each node accesses the network so as to flexibly plan a communication route.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an ad hoc network access method, device, computer equipment and storage medium. Background technique [0002] At present, the mainstream ad hoc network system is the Zigbee system based on the 802.15.4 protocol of the Institute of Electrical and Electronics Engineers (IEEE). The Zigbee network mainly includes the following three types of equipment: terminal equipment, A coordinator and a personal area network (PAN for short) coordinator. The main functions of each device are as follows: end device, end device can include full function device (FullFunctionDevice, referred to as FFD) and simplified function device Reduced Function Device, referred to as RFD), RFD only has simple sending and receiving functions, and cannot forward packets; FFD Usually by sending beacons to achieve synchronization with surrounding nodes, it has the function of forwarding packets;...
