Problems solved by technology

In the case that the relevant subsidiary nodes are not adjacent, it is easy to cause multiple connected links between the two adjacent backbone nodes B and C within two three hops, so the scale of the backbone structure is relatively large. Especially with large network overhead

Embodiment Construction

[0048] In an ad hoc network, each terminal (i.e., node) has the function of routing and switching, and can send and receive information transmitted in the network, and two adjacent terminals (i.e., nodes) can directly establish an "end-to-end" communication link road. In an ad hoc network, an "adjacent node" refers to two nodes with a physical connection between them. In a wireless communication network, such a physical connection generally refers to a wireless connection.

[0049] Hereinafter, the construction method of the ad hoc network backbone structure proposed by the present invention will be described in detail with reference to the accompanying drawings.

[0050] The construction method feature of network backbone structure of the present invention comprises:

[0051] 1. Classify the terminals in the self-organizing network into four types (initial nodes, backbone nodes, connected nodes, and affiliated nodes); the initial type of nodes is the initial node; all backbo...

Abstract

The invention provides a construction method of self-organizing network main structure for realizing a self-organizing network with better rate of expansion, smaller size of main structure and less consumption of network system to improve the transmission efficiency and the property of network. The invention comprises: setting the type of start nodes of all nodes as initial nodes which send the status information pack periodically; setting all initial nodes as main nodes or auxiliary nodes according to the received status information pack of adjacent nodes; the auxiliary nodes receive the status information of adjacent nodes and send the 'adjacent nodes status information pack' periodically; the main codes generate and cooperate the auxiliary nodes to complete the arrangement of connected nodes according to the received 'adjacent nodes status information pack'; when said arrangement is completed, all the nodes of network adjust the type of nodes according to the received adjacent nodes status information pack in present period and the last period.

Description

technical field [0001] The invention relates to a method for constructing a network, in particular to a method for constructing a self-organizing network backbone structure. Background technique [0002] Networks can be divided into two categories in terms of structural composition: networks with a fixed infrastructure and networks without a fixed infrastructure. [0003] In a network with a fixed infrastructure, there are fixed and wired network nodes connected to each other. These nodes constitute the basic architecture of the network, such as a cellular network and a local wireless access network (WLAN). In the cellular network, the basic network structure is composed of base stations. With the base station as the center, the circular (regular hexagonal) area within the base station’s transmission radius forms a “cell”. The fixed and evenly distributed base stations jointly realize the coverage of a certain area by the network. . The user's mobile device is directly con...
