Embodiment Construction

[0057] Such as figure 2 Shown is a wireless ad hoc network communication method with ultra-multi-hop and low delay according to an embodiment of the present invention, which is used in a wireless ad hoc network such as an OFDM wireless ad hoc network, and it is also applicable to wireless ad hoc networks of other systems Networking, suitable for any type of wireless ad hoc network. It is mainly divided into three steps: network topology and basic configuration, channel measurement and result feedback, clustering algorithm and optimization calculation according to the feedback result, and ultra-multi-hop low-latency ad hoc network transmission. The wireless ad hoc network communication method with ultra-multi-hop and low delay specifically includes the following steps:

[0058] Step S1: Determine the network topology of the wireless ad hoc network, and perform initial basic configuration on the wireless ad hoc network;

[0059] Such as image 3 As shown, the network topolog...

Abstract

The present invention provides a wireless ad hoc network communication method with super multi-hop and low delay, including: determining the network topology structure of the wireless ad hoc network, and configuring each node to be switchable in the working mode of amplification and forwarding and decoding and forwarding Work; carry out channel measurement and result feedback, determine the number of nodes in each forwarding cluster according to the measurement results, divide the nodes between the source node and the destination node into several forwarding clusters, and the forwarding cluster consists of a cluster head node in decoding and forwarding mode and subsequent It is composed of at least one relay forwarding node in the amplification and forwarding working mode, or a cluster head node; it performs ultra-multi-hop and low-latency ad hoc network transmission. The communication method of the present invention realizes the self-adaptive clustering combination of super-multi-hop hybrid relay, decomposes the traditional super-multi-hop into several hops, greatly reduces the number of hops that actually generate time delay, and greatly reduces transmission time delay, thereby overcoming The reliability and transmission delay of long-distance ultra-multi-hop communication cannot guarantee the defect of business service quality.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a wireless ad hoc network communication method. Background technique [0002] figure 1 It is a typical ultra-multi-hop wireless ad hoc network transmission system. figure 1 All nodes in the network are expanded according to the chain topology to form a wireless chain network. The wireless chain network is a wireless ad hoc network with a special topology. Freight vehicle operation monitoring and other national key security fields. [0003] At present, the traditional super multi-hop ad hoc network transmission mainly adopts the hop-by-hop transmission method of ad hoc network information cascade, that is, the nodes in the network are responsible for sending local information on the one hand, and are also responsible for receiving the information transmitted by the previous node, and sending The information is decoded and forwarded to the next node until the in...
