Abstract

With the current proliferation of wireless networks and mobile device technologies, the management of moving object databases to facilitate queries over these domains has been extensively studied. While current systems are concerned with tracing the precise location, or paths, of these objects, in many cases it is sufficient to know that the approximate location or path of a moving object is, with certainty, within known bounds. Thus, we present our work on Continuous Approximate Where-About (CAWA) queries, in which mobile sensors sense the presence of an object (not its precise location) and query servers deduce the object’s where-about area from mobile sensor presence updates.

Keywords: Moving object database continuous query presence distributed computing where-about
