Cloud-Based Global Monitoring System for Smart Cities

Within the emergence of smart cities over the world, there is a great need for a set of services that ensure the protection of citizens and cities assets. Several supervisory systems have been deployed everywhere making use of a set of fixed and mobile sensors. Facing the new threats, these systems are unable to ensure the monitoring of large areas that are under the control of different entities which prevent an efficient protection against the malicious activities targeting cities. In this context, this paper proposes a novel cloud-based monitoring system that provides global monitoring services using a set of sensors that are deployed by different supervisory systems, enabling the reconfiguration of sensors according to an efficient scheduling scheme. The efficiency of the proposed model is illustrated through a case study for a camera-based smart city surveillance.
