Embodiment Construction

[0041] A directional antenna-based dynamic time-space domain resource allocation and access method of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Step 1: Listen to the scanning message of the sending node and update the local resource allocation table:

[0043] When a node in the network is powered on, it will preset the angle registration table in advance, and the sending node will update the resource allocation table of the node according to the preset angle registration table, and then send a scanning message under the scanning sending time slot, and the receiving node will receive Update the resource allocation table of this node after scanning the message.

[0044] Step 2: Periodically broadcast resource allocation information of nodes:

[0045] A node periodically sends its resource allocation information to all one-hop neighbor nodes.

[0046] Step 3: Count the number of needs:

[0047] The sen...

Abstract

The invention discloses a dynamic time-space domain resource allocation access method based on a directional antenna, which comprises the following steps of: 1, monitoring a scanning message of a sending node, and updating a local resource allocation table; 2, periodically broadcasting resource allocation information of nodes; 3, counting the demand number; 4, judging whether to release the time slot or apply for the time slot according to the required number of the sending time slots; 5, generating an application or release message according to the request type and the request mechanism; 6, enabling a receiving node to analyze and confirms request items in the request message according to the time slot application request message or the time slot release request message and the resource allocation table, generate a confirmation message and update the resource allocation table; and 7, enabling a sending node to update the resource allocation table according to the received acknowledgement message. According to the invention, the nodes can obtain the right to use more beam channels in the current time slots, and the channel utilization rate and throughput are improved.

Description

technical field [0001] The present invention relates to the field of communication ad hoc network, by designing a dynamic resource allocation and access method based on directional antenna combined with time and space domain, so as to achieve the goal of maximizing the use of channel resources. Background technique [0002] Self-organizing network is one of the hot research contents of communication technology. Its unique multi-hop decentralized dynamic networking method makes self-organizing network have high application value in military communication, post-disaster emergency communication, temporary conference network, etc. . In an ad hoc network, the MAC protocol is mainly responsible for channel access control and allocation of channel resources. The performance of the MAC protocol plays an important role in the performance of the entire ad hoc network. The traditional time division multiple access technology access mechanism is to divide the channel into different co...
