Research on Application of Game Theory in the Information Fusion

The information fusion under the circumstance of multi-source information conflict is the must be confronted problem for the application of information fusion theory. The paper combined game theory and information fusion theory and brought out a method to realize the situation assessment function of information fusion, which takes the game player, strategy and payoff as basic element, the core functions of situation assessment as general game fusion model, network nodes as the multi-source information, directed edge as strategy interaction, condition probability as the uncertainty of fusion, the Bayesian network as problem representation and solving method.
