Problems solved by technology

However, these studies are generally based on a single path, which cannot well adapt to network dynamic changes or changes in application requirements.
Routing protocols based on multipath generally require more control overhead, and may require disjoint characteristics between multipaths, making multipath establishment more difficult

Embodiment Construction

[0009] Network operation is generally divided into two stages. After the network deployment is completed, it will enter the initial configuration stage. In this stage, network synchronization is performed, necessary routing information is collected to establish routing tables, etc.; after the initial configuration stage is completed, the network enters the data transmission stage. The node selects the next hop forwarding node according to the routing table, and reports the data to the sink node through hop-by-hop transmission.

[0010] In the initial configuration stage, the network first establishes the gradient information and routing table required for routing. Different from other routing protocols that only establish single-path routing information based on a single forwarding strategy, in order to improve the life cycle of the network, the present invention establishes multi-paths based on the remaining energy of nodes and expected transmission times (ETX). The ETX o...

Abstract

The invention belongs to the technical field of wireless network protocols, particularly relates to a multi-path data transmission method of an industrial wireless sensor network based on surplus energy and expected transmission count. According to the invention, a mechanism is mainly used for enabling a data sending node to choose a node with relatively plentiful energy and relatively low transmission expense to be a next hop node to achieve the purpose of saving and equalizing network energy consumption; the mechanism requires the network to comprise multiple sensor nodes and a single sink node, each sensor node has limited electric quantity, and the sink node has independent electric quantity. The method specifically comprises the following steps: based on surplus energy levels, multiple minimal expected transmission count paths are built in the network, and when a node forwards data, the node chooses a node with minimal expected transmission count in forwarding nodes with relatively high surplus energy to be the next hop forwarding node, or a forwarding node with maximum surplus energy to be a next hop node of a packet until the data arrives at an aggregation node.

Description

technical field [0001] The invention belongs to the technical field of wireless network protocols, and in particular relates to a multi-path data transmission method for an industrial wireless sensor network based on residual energy and expected transmission times. This mechanism is mainly used to enable the data sending node to select a node with more energy and lower transmission overhead as the next hop node during data transmission, so as to achieve the purpose of saving and balancing network energy consumption. Background technique [0002] In recent years, the relevant technologies in the field of wireless sensor networks have attracted extensive attention from academia and industry because of their wide application, and have achieved rapid development. [0003] When designing a wireless sensor network, it must be considered that wireless sensors have their own limitations. Due to the limitations of cost and volume in practical applications, the processing power, wire...
