Dynamic Selection Method for Cooperative Decision-Making Center of Multi-UAV System based on Cloud Trust Model

Abstract

This paper is devoted to designing a kind of dynamic selection method for cooperative decision-making center of multi-UAV system. In cooperative multi-UAV system with mixed and layered structure, the individual of cooperative decision-making can be called Decision-Making Center (DMC). The random fault of individual or interference, deception and malicious attack to the DMC will lead to the instability of the system. Traditional method based on formation leader selecting is feasible in normal environment, but not available when the cooperative system has been deceived or interfered. The existing methods will produce a certain deviation, even the system is deceived or intercepted. According to all of above problems, the ability of decision to provide the DMC has been modeled as its trust value, include trust degree (TD) and reputation degree (RD). Through the information which is interacting between UAVs and using of the Cloud Model to enhance the adaptability of the environmental uncertainty, a new method defined as Dynamic DMC Selection based on Cloud Trust Model (DDMCSCTM) has been built. It can adaptively select the best DMC in environment of deceived and interfered. Experimental results show that it can achieve better effect.
