Empowering smart cities through interoperable sensor network enablers

Sensor Networks are increasingly playing a fundamental role in many application scenarios such as agriculture, maritime, healthcare, industrial and even military application. However, the high heterogeneity of sensor networks poses a great challenge in interoperability and cooperative work, and the building of technological bridges among wireless sensor network (WSN) islands is more and more a must for smart cities for an efficient operation. In this paper, we present a model for an Area Sensor Network (ASN) that combines and connects small networks (Body Sensor Networks), WSNs and even fixed sensor networks within a particular area of interest. Initial tests show that the combination of sensed data from multiple sources (sensor networks) produces synergetic services useful for smart cities.
