Embodiment Construction

[0025] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0026] In order to solve the deficiency of the single channel access mode in the existing multiple access methods, the present invention provides a multiple access method that can select different channel access modes according to different traffic levels. The advantages of the way to achieve access optimization. Including: the central control node (CCN) determines the current traffic level, selects the corresponding channel access method and sends a dedicated control packet to the nodes controlled by the CCN by broadcasting; and each node according to the received Steps for channel access.

[0027] Assumptions:

[0028] S current Indicates the current throughput, 0≤S current ≤1;

[0029] S 1-门限 Indicates the first traffic threshold value of the light traffic threshold, 0≤S 1-门限 ≤1;

[0030] S 2-门限 Indicates t...

Abstract

This invention relates to an adaptive multiple access methods, include: center control nodes determine the current volume of business class, choose corresponding to the way Channel Access Control Center in the control nodes released; each node in accordance with the letter received by the road access to access. It also relates to a central control node, including monitoring unit, all the nodes used to control the central node; and grading modules, connecting with the monitoring unit used to determine the current volume and choose corresponding access method. This invention chooses different method for different volume. The invention determines suitable method for every volume to make the access best.

Description

technical field [0001] The invention relates to an adaptive multiple access method, in particular to a multiple access method for selecting a corresponding channel access mode according to the current traffic level, which is applicable to mobile ad hoc networks, wireless sensor networks, wireless Access to the network and other systems. Background technique [0002] The multiple access (or media access control) method solves the problem of how multiple nodes or users share channel resources quickly, efficiently, fairly and reliably. According to the way of channel allocation, it is usually divided into three ways: fixed allocation, random access and on-demand allocation. [0003] Currently, channel allocation methods directly applied in mobile wireless communication networks generally adopt a single random access and on-demand access method. [0004] In the multiple access method of random access, when each node shares the wireless broadcast channel in a multi-hop network ...
