Abstract

A mesh network flow control method comprising: allocating a receiving window of a certain size between a parent node and each child node; the child node transmitting a window request to the parent node prior to transmitting a packet; upon receipt of the request, the parent node extracting the sequence number of the request of the child node; comparing the sequence number with a sequence number of the packet last received; calculating the size of an available window and replying to the child node with the size; and the child node transmitting the packet according to the size. Another method includes: a root node broadcasting information concerning a connection state between the root node and a server in a management frame of Wi-Fi, such that through information communication within a network, each node within the network can obtain the information, and then devices within the network transmit packets to the root node, thereby avoiding occupancy of bandwidth by unnecessary packet-transmissions.
