[Retracted] Data Mining-Based Tracking Method for Multisource Target Data of Heterogeneous Networks

Table 2

Classification of treatment results.

Number	Condition	Explain	Handle
1	The sensor does not meet the switching condition at the current sampling time	The sensor data is still stable	Without any operation, the sensor data can be used for tracking
2	The data of the current sampling time and the first sampling points meet the switching conditions	The sensor cannot get the target status data normally	Switch action is needed to select the next priority sensor data for tracking
3	At the current sampling time, the sensor meets the switching condition, but the first sampling points do not meet the switching condition	The sensor has an extreme point	The target state vector corresponding to the sensor is replaced by its least square curve fitting result
