Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] Method example:
[0033] The farmland wireless sensor network communication method for resisting cascading failure of the present invention, the specific implementation includes the following steps:
[0034] 1. Node deployment.
[0035] (1) In the area to be monitored in the farmland, first determine the deployment area of the sink node (base station that collects data) and other sensor nodes (or other wireless nodes with relay function), such as figure 1 As shown, the sink node 10 is set in the middle of the area to be monitored, and the monitoring area around the sink node is divided into five layers as node areas, including the first layer node area 101, the second layer node area 102, and the third layer node area. 103. The fourth layer node area 104 and the fifth layer node area 105, these five layer node areas are the deployment areas of sens...

The invention relates to a farmland wireless sensor network and a communication method, belonging to the technical field of wireless sensors. The wireless network includes a collection node in the center of the communication area and sensor nodes around the collection node; several layers of annular areas are formed around the collection node; the sensor nodes are distributed in each annular area; during networking, the sensor nodes in the innermost annular area The collection node establishes a first communication channel, and the sensor nodes in other annular areas establish a first communication channel with at least one sensor node in the adjacent inner annular area; each sensor node also establishes a first communication channel with at least one sensor node in the annular area where it is located. Two communication channels; after each sensor node obtains data, it transmits data through the first communication channel with a first set probability, and transmits data through the second channel with a second set probability; if a certain communication channel fails, it transmits data through another One communication channel transmits data; the first set probability is greater than the second set probability.
Description
technical field [0001] The invention relates to a farmland wireless sensor network and a communication method, and belongs to the technical field of wireless sensors. Background technique [0002] Due to the influence of the production organization, the farmland wireless sensor network presents different characteristics in terms of network topology and information transmission methods: (1) There are many interference factors in the farmland operation process, the farmland gradient environment, the network deployment range is large, and the deployment density is small. , it is necessary to introduce relay nodes and perform hierarchical clustering. Factors such as dynamic heterogeneity and chain-directed transmission make the dynamic uncertainty of network behavior increase significantly, which makes the farmland wireless sensor network show obvious topology variability; (2 ) Large-scale farmland monitoring areas require coordinated monitoring of nodes, and it is inevitable th...
