Methodologies for handling ‘destination unknown’ range queries during mobility

Location based services (LBS) are key components of mobile applications. LBS provide information related to resources based on the user´s current query location. Offering services to the travelers based on queries is one of the salient applications of LBS. Range queries are kind of mobile queries, which may involve distance and/or time parameters. Most of the LBS focus on destination based range queries to be addressed for identifying and suggesting resources. Identifying resources in the traveling path where `destination unknown´ is an interesting area of LBS. More specifically, when there are deviated paths, suggesting resources for `distance based range queries´ is still a challenging task. In this paper, we focus on proposing methodologies for identifying and suggesting resources for `destination unknown´ range queries giving importance to deviations and junctions available in the road network.
