Broadband ad-hoc network time slot resource dynamic allocation method based on multilevel frame structure

Abstract

The invention belongs to the technical field of an ad-hoc network in the field of communication and discloses a broadband ad-hoc network time slot resource dynamic allocation method based on a multilevel frame structure. The method comprises the steps that A1, a TDMA star network which takes a master node as a center is established; A2, the master node establishes a three-level frame structure andsends broadcast information to sub-nodes; A3, the sub-nodes receive the broadcast information and then enter silent receiving states until the sub-nodes have to-be-sent business; A4, the sub-nodes send time slot request frames to the master node; A5, the master node receives the time slot request frames sent by the sub-nodes and allocates time slots to new requests of the sub-nodes through utilization of an online time slot allocation mechanism; A6, the master node broadcasts a time slot allocation scheme in a next superframe; and A7, the sub-nodes receive and analyze the time slot allocationscheme. The method provided by the invention is characterized by high whole network resource utilization rate and low online operation complexity and is particularly applicable to a broadband ad-hocnetwork application with a high QoS demand.

Description

technical field [0001] The invention belongs to the technical field of broadband ad hoc network for mobile communication, and in particular relates to a method for dynamically allocating time slot resources of a broadband ad hoc network based on a multi-level frame structure. Background technique [0002] Sufficient time slot resources are the basic requirements to ensure the effective transmission of various services in the time division multiplexing network. With the increasing proportion of multimedia services such as video and images in all wireless services, it has become normal for multiple terminals to compete and share limited resources. Without effective resource scheduling methods, the network will gradually become congested, and ensuring quality of service (QoS) under limited resources has become a major challenge in broadband networks. [0003] The current resource scheduling methods in 3G, 4G and other mobile communication networks have been fully verified, and...

Problems solved by technology

This time slot allocation method can overcome the waste of resources caused by static resource allocation to a certain extent, but it also has a relatively large defect, that is, this allocation method has no online judgment mechanism and cannot respond to rapidly changing network requirements in a timely manner.
