Based on the wireless sensor networks

the localization of target track application is researched.When localization of target track is made

how both can the guarantee tracking accuracy and reduce the energy consumption effectively

in view of this question

one simple weighting coordinates center of mass localization method is proposed

through the goal localization

one kind track method based on the survey information is given

the method realization is simple.The performance analysis indicates

the proposed localization track method can effectively

reduce the energy consumption

extend the node and the network life

basic may meet the needs of the battlefield target tracking.
