Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] refer to Figure 1 to Figure 3 ,like Figure 1 to Figure 3 As shown, a wireless channel allocation method includes:

[0042] Base station action: In a wireless communication system, large-scale offline nodes quickly move to the vicinity of a fixed base station. When a burst request accesses the base station, the base station broadcasts a BEACON message, and the node sends an access request according to the BEACON message; Judging the competition intensity of the channel competition situation, determining the channel competition mode, and notifying the nodes;

[0043] Wherein, when a node ...

Abstract

The invention discloses a wireless channel allocation method and relates to a wireless channel allocation technology. The wireless channel allocation method comprises the following steps that: a basestation acts: in a wireless communication system, a large-scale offline node quickly moves to the vicinity of a fixed base station, the base station broadcasts a BEACON message when the access to thebase station is suddenly requested, and the node sends an access request according to the BEACON message; the base station judges the competition intensity according to the competition condition of the nodes in a dense node group for the channels, determines a channel competition mode and informs the nods; the node actions: the node synchronizes a competition mode and reserves a service channel; after the reservation succeeds, communication is completed on a specified service channel; the occupied channel is released after the node communication is finished; utilization of traffic channels isincreased. The method provided by the invention effectively solves the problem that the high-speed dense node group cannot be timely accessed to the service channel due to high node density and high movement speed, and the fixed base station has the capability of simultaneously working on the CH and SCH channels.

Description

technical field [0001] The invention relates to a wireless channel allocation technology, in particular to a wireless channel allocation method for fast mobile dense node groups bursting into a fixed base station. Background technique [0002] At present, with the large-scale increase of wireless mobile nodes and the increasing demand for accessing the network during the movement process, in a specific scenario, a group of fast-moving dense nodes is required to burst into a fixed base station. Come to great challenge. The traditional method cannot meet the real-time requirements of nodes accessing the base station. An efficient wireless channel allocation method for fast mobile dense node groups bursting access to fixed base stations is of great significance for fast mobile node networking and access to wireless base stations. It can not only improve timeliness and improve service channel utilization, but also can Improve communication efficiency. [0003] The channel all...
