Problems solved by technology

[0004] According to the above description, it can be seen that the existing technology establishes a unique fixed route between the sensor node and the sink node. Then, when the only route is congested, transmitting data through this route will cause a large amount of data loss , so that the transmission of data cannot be guaranteed

Abstract

The invention provides a data routing method and a sensor node. The method comprises the following steps: establishing a plurality of routes to a sink node; receiving a negative feedback command sent from at least one next-hop node on the plurality of routes, wherein the negative feedback command comprises the value of the parameter level of the at least one next-hop node; calculating the forwarding probability of a plurality of next-hop nodes on the plurality of routes according to the values of the parameter levels of the plurality of next-hop nodes on the plurality of routes, wherein the values of the parameter levels of the plurality of next-hop nodes comprise the value of the parameter level of the at least one next-hop node and the stored values of the parameter levels of the other next-hop nodes in the plurality of routes; and selecting the next-hop node according to the calculated forwarding probability of the plurality of next-hop nodes on the plurality of routes, and sending the data to the selected next-hop node. The sensor node provided by the invention comprises an establishing module, an interface module, a calculating module and a routing module. The invention can ensure the data transmission.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to data routing methods and sensor nodes. Background technique [0002] Wireless sensor network (Wireless Ssensor Networks, WSN) is a multi-hop self-organizing network formed by wireless communication. A typical wireless sensor network usually consists of three parts: sensor nodes, sink nodes (called sink nodes) and management terminals. Among them, the sensor nodes can monitor, perceive and collect data of various environments or monitoring objects in real time (such as temperature, humidity, noise, light intensity, pressure, soil composition, physical information such as the size, speed and direction of moving objects), and the collection The data is processed and sent to the sink node; the sink node is the central node of the wireless sensor network, which is used to receive and respond to the commands of the management terminal, analyze and process the dat...
