A data associaed algorithm based on graphic model which combined with target category message is proposed.The goal is to enhance data association accuracy of the multi-sensor networks.Through the analysis of target category information based on graphic model

the apex compatible function and the wired compatible function formula are suitably revised

and combining with category message’s likelihood function to change compatible function which originally use kinematics information.The category message is applied to connected algorithm.Through comparison of simulation result

it is confirmed that category message can be used to improve the connected performance of multi-objective.
