Enhanced Network Based Query Processing in Road networks
The location aware portable devices are widely increased. This rise to the usage of location based services to reveal their own location and needed location. The existing query processing techniques uses the private information of the user. It threatens the user identity, privacy and confidentiality. To overcome this, instead of spatial region with one query reference point to process the query...
متن کاملUPBI: An Efficient Index for Continues Probabilistic Range Query of Moving Objects on Road Network
With the development of mobile terminal technology, the continuous range query of moving objects on road network has been widely applied in the field of transportation, military and communication. In practical applications, the sampling frequency of positioning equipment could not eliminate uncertainty, resulting in moving objects’ position uncertainty between two adjacent samples. The index ex...
متن کاملSecure Multidata Owner K-NN Query Processing on Road Networks using Voronoi Network
Mobile devices with geo-positioning capabilities (e.g., GPS) enable users to access information that is relevant to their present location. Users are interested in querying about points of interest (POI) in their physical proximity, such as restaurants, cafes, ongoing events, etc. With the everincreasing use of smart phones and tablet devices, location-based services (LBSs) have experienced exp...
متن کاملLocation-based Query Processing on Moving Objects in Road Networks∗
Location-based services are increasingly popular. In this paper, we present our novel design of a system to process location-based queries on MOVing objects in road Networks (MOVNet, for short) that efficiently handles a large number of spatial queries over moving objects in a stationary road network. MOVNet utilizes an on-disk R-tree to store the network connectivities and an in-memory grid in...
متن کاملAnonymous Processing of Query in Road Networks
The increasing availability of location-aware mobile devices has given rise to a flurry of location-based services (LBS). Due to the nature of spatial queries, an LBS needs the user position in order to process her requests. On the other hand, revealing exact user locations to a (potentially untrusted) LBS may pinpoint their identities and breach their privacy. To address this issue, spatial an...
