Query Processing in Mobile Environments: A Survey and Open Problems

Abstract

Mobility of units has become a rapidly growing domain. Scientific and industrial community agrees that the progress realized in wireless networks encouraged a strong development potential for new services and applications; specially the location-based ones. Location-based services initiated the need for several new types of query in database field. These queries have different constraints and characteristics. Our objective in this paper is to propose a survey on the main work related to mobile queries. We pay a particular attention to the location issue.
