Node arrangement method of wireless sensor network for monitoring forest fires

Abstract

The invention provides a node arrangement method of a wireless sensor network for monitoring forest fires. The node arrangement method includes the following steps: (1) arranging aggregation nodes along transmission wires in a forest; (2) arranging detection nodes according to the detection radius of the nodes in the direction perpendicular to the transmission wires with the arranged aggregation nodes as the basis; (3) arranging simplified nodes for assisting communication between the detection nodes as well as between the aggregation nodes and the detection nodes; (4) complementing the simplified nodes at partial node positions. The node arrangement method can meet application requirements of modern forest fire monitoring, provides an arrangement method of the nodes of the wireless sensor network for forest fire monitoring, is favorable for improving the position and the role of the wireless sensor network in forest fire early warning, breaks through the traditional node arrangement thinking, prolongs the service life of the whole wireless sensor network, and improves reliability of the wireless sensor network.

Description

technical field [0001] The invention discloses a wireless sensor network node deployment method for forest fire monitoring, belonging to the fields of wireless sensor networks and electronic monitoring. Background technique [0002] Forest fire is one of the important disasters of forestry in the world, which occurs in a certain number every year, causing heavy loss of forest resources and serious environmental pollution. Forest fires are sudden and random, and can cause huge losses in a short period of time. Therefore, once a fire occurs, rescue measures must be taken at an extremely fast speed. Whether the rescue is timely and whether the decision-making is appropriate depends on whether the forest fire behavior is discovered in a timely manner, whether the location is accurate, and whether the fire analysis is reasonable and accurate. . For this reason, a lot of work has been done on how to prevent, reduce and control forest fires at home and abroad. By realizing the s...

(3) The node energy of the wireless sensor network is limited, and the network cycle life is limited. Replacing the node power supply or the sensor network node will consume huge manpower and material resources

Although there are green power supply forms such as solar energy and wind power, they are not stable and reliable enough, especially in the difficult environment of forests, where they are prone to failure, which limits their scope of use.
