Abstract

The invention discloses a priority forwarding method based on path number. The back-off mechanism of this method once the forwarding node encounters a data collision conflict, the size of the back-off window of the collided forwarding node will be determined by the number of paths that the forwarding node can choose, and the retransmission time of the node is staggered by the difference in the number of forwarding paths. Let the data of forwarding nodes with fewer forwarding paths be sent first, which can not only ensure that the data of forwarding nodes with fewer paths can be sent out, but also avoid excessive congestion in some areas of data transmission, and effectively use the bandwidth of the entire network. Increase the throughput of the network and improve the data receiving rate. The present invention is based on a competition-based MAC protocol. By adopting a reasonable back-off mechanism, the node data can balance the flow load, make full use of the bandwidth, reduce the power consumption of data transmission, and avoid inter-node interference at the same time. in the network.

Description

technical field

[0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a priority forwarding method for wireless sensor networks based on the number of paths, which is applicable to fast acquisition scenarios. Background technique

[0002] With the in-depth development of wireless sensor network technology, the transmission data of nodes is no longer satisfied with a single light load, and has gradually entered the era of heavy loads such as sound and images. The fast acquisition scene for heavy load processing has emerged as the times require, and has become One of the current technology research hotspots. Fast collection scenarios require fast data collection and effective handling of heavy traffic loads, but sensor nodes have very limited energy and storage space, and can only store and process data limitedly, which requires us to design a method to make data transmission reasonable Use the space capacity of network ...
