Databases for Tracking Mobile Units in Real Time

  title={Databases for Tracking Mobile Units in Real Time},
  author={Ouri Wolfson and Liqin Jiang and A. Prasad Sistla and Sam Chamberlain and Naphtali Rishe and Minglin Deng},
In this paper we consider databases representing information about moving objects (e.g. vehicles), particularly their location. We address the problems of updating and querying such databases. Specifically, the update problem is to determine when the location of a moving object in the database (namely its database location) should be updated. We answer this question by proposing an information cost model that captures uncertainty, deviation, and communication. Then we analyze dead-reckoning… CONTINUE READING
