Recent cities are filled with sensors connected to a network. For example, parking meters monitor occupancy of parking lots. Environment sensors reports density of air pollutant periodically. The data acquired from the sensors are collected, processed, and delivered not only to the city residents, but also to actuators. The actuators include, for example, interactive public displays that inform the residents about traffic conges- tion in usual, speakers mounted on city office cars that triggers the residents to escape from the current location on a fata disaster. Those actuators work as the interface between the city and the residents. Better orchestration of these sensor/actuator services thus results in better city services provided to the residents.
The problem is that the services are distributed. They are installed in many places on the ground, such as at parking lots and environment sensing stations. Some of them are unmanned flying objects with sensors/actuators mounted. Some others, such as satellites, serve the residents from the space. Physical distribution of these services are thus horizontal and vertical. They are also distributed in terms of networks. Some services are connected to the Internet directly, while some others are via cellular phone networks. Vertial and horizontal orchestrations are thus required both in cyber and physical spaces.
The aim of smart city lab at Keio University SFC is to address these challenges and take a new research initiative towards making the cities to be smart. In addition to theoretical research development, we provide practical research tools and applications in cooperation with several international cities, companies and people.
