Wireless tree network access control method and network node equipment

Abstract

The invention provides a wireless tree network access control method and network node equipment. The access control method comprises the following steps of (1) dividing the transmitting capacity of a node into transmitting capacity, namely internal transmitting capacity, for communication among intra-network nodes and transmitting capacity, namely external transmitting capacity, for communication between the intra-network nodes and extra-network nodes; (2) performing two-way communication in a time division duplex mode between a father node and all child-nodes of the father node as well as between the father node and a father node of the father node, wherein the wireless communication between the father node and all the child-nodes of the father node as well as the wireless communication between the father node and the father node of the father node are performed in different channels respectively, i.e., the communication between the nodes at different levels of a wireless tree network can be performed simultaneously. The invention further comprises network node equipment of the wireless tree network. The equipment provided by the invention is unique in structure. By utilizing the method provided by the invention, the utilization ratio of the existing wireless spectrum resources can be fully exerted, multiple access interference is reduced, and the wireless tree network can meet the urban multimedia communication demand in a remote region or under an emergency case.

Description

technical field [0001] The invention belongs to the field of information technology, and mainly relates to a wireless tree network access control method and a network node. Background technique [0002] In some mountainous areas, remote areas or areas with underdeveloped traffic, the cost of setting up optical fiber or other wired network communication equipment is very high. Building a wireless tree network to achieve large-area communication coverage in some remote areas is a quick and low-cost overall solution. However, while the various existing wireless communication networks bring convenience to people, they also have inherent shortcomings such as insufficient spectrum resources, susceptibility to interference, especially multiple access interference, etc., especially unable to meet the needs of multimedia communication in remote areas or in emergency situations. [0003] Although the tree network is a common network topology, there have been a few literatures that ha...
