A multi-sensor management method based on tracking accuracy and energy consumption indicators

Abstract

The invention discloses a multi-sensor management method based on tracking accuracy and energy consumption index, which converts the sensor management problem into a multi-evaluation decision-making problem, and abstractly maps each sensor node in the sensor network to a focal element in DSmT theory , so as to construct the corresponding sensor identification framework and superpower set space, and realize the modeling of the sensor itself. Then, according to the tracking accuracy and energy consumption indicators of each sensor combination, the decision matrix under multiple evaluation indicators is obtained. Finally, use the BF-TOPSIS multi-evaluation index strategy to obtain the best combination of sensors at the current moment, and use it as the sensor to track the target at the next moment, so as to realize the target tracking. The invention completes the modeling of multi-sensor management through the DSmT theory, reduces the uncertainty problem in sensor selection; through the multi-evaluation index decision-making strategy, the optimal sensor at the current moment can be selected to the greatest extent, with stable performance and strong portability.

Description

technical field [0001] The invention belongs to the technical field of information fusion, in particular to a multi-sensor management method based on tracking accuracy and energy consumption indicators. Background technique [0002] With the mass production of cheap sensors and the great improvement of their monitoring performance, wireless sensor networks have achieved unprecedented development in various fields (such as environmental monitoring, industrial perception, fault diagnosis, military use, robot control, etc.). Among them, the target tracking problem based on sensor network is one of the research hotspots of sensor network. However, due to the physical limitations of the sensor network (such as: the communication bandwidth of the sensor network, the battery capacity carried by the sensor, etc.), only a small number of sensors can be used for target tracking at a certain moment. Therefore, it is necessary to design an appropriate sensor management strategy, and se...
