Problems solved by technology

However, the smaller the duty cycle of the node, the longer the sleep time at the node is, so when the target passes by, the probability of the node being in the sleep state is higher, and the target cannot be detected
The monitoring area where the target may pass through the sensor network is not detected, resulting in serious accidents

Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing and embodiment

[0035] A node duty ratio self-adaptive setting method for efficient target monitoring. In a wireless sensor network, the duty ratio of each node is set according to the distance from the base station. The farther the node is from the base station, the node's The greater the sensing duty cycle or communication duty cycle, the closer the node is to the base station, the smaller the sensing duty cycle or communication duty cycle of the node

[0036]On the one hand, the sensing duty cycle selected by the node in the area farther away from the base station is greater than the sensing duty cycle in the existing method. The farther away from the base station, the greater the sensing duty cycle of the node, thereby improving the quality of target monitoring; On the other hand, the remaining energy in the remote base station area is used to increase the communication d...

Abstract

The invention discloses a node duty ratio self-adaptive setting method for efficient target monitoring. The method comprises the following steps: according to the distance condition between a node and a base station, a far base station adopting a large duty ratio, and a near base station adopting a small duty ratio. The residual energy at the far base station region is sufficiently utilized, and the duty ratio of the node in the far base station region is improved. The omission ratio and the detection delay in the target monitoring can be reduced when the perception duty ratio of the node is improved; and the transmission delay in the target monitoring can be reduced when the communication duty ration of the node is improved, thereby effectively improving the target monitoring quality, and improving the energy utilization rate of a sensor network.

Description

technical field [0001] The invention belongs to the field of wireless network data target monitoring, in particular to an adaptive setting method of node duty cycle used in high-efficiency target monitoring. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of sensor nodes that communicate with each other through multi-hop wireless links and in a self-organizing and multi-hop manner. It can be widely used in industrial monitoring, agriculture, civil, environmental monitoring, battlefield , ocean, fire and other special environments and applications, it is considered to be one of the key basic technologies of the future important IoT network. An important application of wireless sensor networks is to monitor targets. For example, in the battlefield, sensor networks are deployed in areas where the enemy may pass, and when enemy tanks and chariots pass by, they can quickly report to the control center. The key problems in ...
