Taking into account the application layer quality of service and wireless link security, a dynamic spectrum management scheme is proposed to minimize the system cost of cyber-physical surveillance system for transportation. Video distortion is considered as the application layer quality of service metric, and the system cost is defined as a combination of distortion and security cost. The problem is formulated as a restless bandit system to utilize the current and historical information for system optimization.
