Embodiment Construction
[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, a target tracking method for a wireless sensor network based on distributed processing of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only for explaining the present invention, and are not intended to limit the present invention.
[0037] A wireless sensor network target tracking algorithm based on distributed processing of the present invention is to overcome the traditional tracking method's complex algorithm, large amount of information transmission, large amount of calculation, and large energy consumption. It introduces the extended Kalman filter algorithm At the same time, the principle of minimum state error covariance matrix trace is used to select task nodes, which reduces processor energy consumption, reduces da...
