碩士 / 輔仁大學 / 資訊工程學系 / 101 / In recent years, smartphone are widespread and refined in the world. This technology improved convenience of our life. Such as build in GPS or AGPS mobile devices is more and more popularity. And unlimited the 3rd generation data transfer for smartphone user, LBS service is an important type of smartphone application. In LBS service, there is a method to find amone all moving objects. That is continuous k-Nearest Neighbor (CKNN) query; this algorithm is a moving object at each timestamp. In road network relate paper, they always focus on processing such as the shortest network distance between objects. Another issue is the bottleneck in LBS to ITS (Interlligent Transport System). In trandition improve performance is change hardware.
In this paper, we first highlight the real road network, we added a parameter “traffic time” to improve the real world’s road network. We consider the real network not only the distance between objects, but also the real traffic time. Second highlight is how to import trandition ITS. We use an ITS base on cloud computing, namely the CloudITS. The system is a web service by RESTful Web Service architecture. It proves smartphone uses to request a light query for CloudITS.
