Abstract

The embodiment of the invention provides a method and a device for confirming an interference performance applied to a wireless sensor network. The method comprises the following steps: confirming a to-be-tested node in a plurality of sensor nodes in the wireless sensor network; confirming at least one available network signal strength value of the to-be-tested node in a preset measuring time period; utilizing a preset APD measuring mode to acquire at least one APD statistical result corresponding to a network interference signal of the to-be-tested node in the preset measuring time period; utilizing a preset SER-APD model, at least one APD statistical result and at least one available network signal strength value to confirm the interference performance of the to-be-tested node in the preset measuring time period, wherein the APD is defined as amplitude probability distribution and the SER is defined as symbol error ratio. Compared with the prior art, the solution has the advantages that the high precision and low processing cost can be ensured when the interference performance of the sensor node in the wireless sensor network is confirmed.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a method and device for determining interference performance applied to wireless sensor networks. Background technique [0002] WSN (Wireless Sensor Network, wireless sensor network) is a new generation of sensor network, which is composed of multiple sensor nodes distributed in a certain area for monitoring and collecting valuable information. Distribute the information of various monitoring objects in the area, process the information, and finally transmit it to the user equipment. For wireless sensor networks, its characteristics include limited node energy, low transmission bandwidth, and susceptibility to interference; and the main factor affecting the transmission performance of wireless sensor networks is interference. [0003] Specifically, when the sensor node demodulates the received data signal, there will be one or more interference signals at the sensor node,...
