TAILIEUCHUNG - STECEQL: A spatio-temporal constraint event query language for internet of vehicles

In STeCEQL, we use time interval as temporal model and grid map as spatial models. We give the syntax and operational semantics of STeCEQL based on the temporal and spatial model. Finally, our experiments illustrate the effectiveness of the operational semantics. | International Journal of Computer Networks and Communications Security VOL. 2, NO. 12, DECEMBER 2014, 448–455 Available online at: ISSN 2308-9830 STECEQL: A Spatio-Temporal Constraint Event Query Language for Internet of Vehicles HUIYONG LI1, YIXIANG CHEN2 AND YUJING MA3 1, 2, 3 Software Engineering Institute, East China Normal University, Shanghai, . China E-mail: 1lihuiyongchina@ ABSTRACT In recent years, the complex event technology has been widely used in the monitoring and real-time querying information of the internet of things. The internet of vehicles is a novel researching area of the intelligent transportation systems, which developed with the technology of internet of things. It is different from the traditional internet of things. There are a large number of moving objects and they will produce large amounts of temporal and spatial information in the internet of vehicles. It becomes the core issue of the complex event technology in the internet of vehicles, how to effectively represent and process these information of the moving objects. We propose a novel temporal and spatial constraint complex event query language STeCEQL for the internet of vehicles. In STeCEQL, we use time interval as temporal model and grid map as spatial models. We give the syntax and operational semantics of STeCEQL based on the temporal and spatial model. Finally, our experiments illustrate the effectiveness of the operational semantics. Keywords: Event Driven Architecture, Event Query Language, Internet of Things, Internet of Vehicles, Grid Map, Mobile Systems. 1 INTRODUCTION With the development of Internet of things (IoT)[1]and Cyber-Physical System(CPS)[2], many new methods and viewpoints were proposed to solved the problem in the research of Intelligent Transportation Systems (ITS). The Internet of Vehicles use the vehicle-mounted electronic sensing device[3], the mobile communication technology, the car navigation system, the information .
