Embodiment Construction

[0037] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0038] Such as Figure 1 to Figure 12 Shown, the time slot reservation method of the present invention based on the TDMA frame structure of directional multi-beam antenna comprises the following steps:

[0039] Step 1, setting up a network node in the form of a directional multi-beam antenna, the directional multi-beam antenna generates multiple transmit beams and multiple receive beams at the same time, and the duplex working mode of the directional multi-beam antenna is full-duplex mode;

[0040] Step 2, the time frame of the TDMA frame structure is divided into three sections: a neighbor node discovery section, a time slot reservation section, and a data transmission section;

[0041] Step 3. Maintain and establish two tables for each node in the network. The two tables include the n...

Abstract

The invention discloses a time slot reservation method based on a time division multiple address (TDMA) frame structure of a directional multi-beam antenna. The method comprises the following steps: I, setting a network node of a directional multi-beam antenna form, and generating a plurality of transmission beams and a plurality of receiving beams at the same time by the directional multi-beam antenna, wherein a duplex working mode of the directional multi-beam antenna is a full duplex mode; and II, partitioning a time frame of the TDMA frame structure into a neighbor node finding segment, a time slot reservation segment and a data transmission segment. In the time slot reservation method based on the TDMA frame structure of the directional multi-beam antenna disclosed by the invention, the directional multi-beam antenna is introduced into an Ad Hoc network, thereby simplifying a neighbor node finding process. Moreover, efficient conflict-free reservation of a data time slot is realized by an access priority mechanism, a queue priority mechanism and RTS/CTS/CONF three-step handshake, thereby remarkably increasing the network capacity, reducing conflicts and providing higher service quality.

Description

technical field [0001] The invention relates to a time slot reservation method, in particular to a time slot reservation method based on a TDMA frame structure of a directional multi-beam antenna. Background technique [0002] With the improvement of user requirements and the development of antenna technology, more and more researches apply directional antennas to wireless Ad hoc networks. The Ad Hoc network is a temporary autonomous system composed of a group of mobile nodes with wireless transceiver capabilities. It has the characteristics of no center, self-organization, self-healing, multi-hop network topology and dynamic changes. and other fields have a wide range of applications. The omnidirectional antenna used in the traditional Ad Hoc network seriously limits the performance of the network. Therefore, introducing the directional antenna into the Ad Hoc network has become a research hotspot. Applying directional antenna technology to wireless AdHoc networks can red...
