Load Shedding in Mobile Systems with MobiQual [PDF]

IEEE Transactions on Knowledge and Data Engineering, 2011
In location-based, mobile continual query (CQ) systems, two key measures of quality-of-service (QoS) are: freshness and accuracy. To achieve freshness, the CQ server must perform frequent query reevaluations. To attain accuracy, the CQ server must receive and process frequent position updates from the mobile nodes.
