Abstract EN
With mobile moving range queries, there is a need to recalculate the relevant surrounding objects of interest whenever the query moves.
Therefore, monitoring the moving query is very costly.
The safe region is one method that has been proposed to minimise the communication and computation cost of continuously monitoring a moving range query.
Inside the safe region the set of objects of interest to the query do not change; thus there is no need to update the query while it is inside its safe region.
However, when the query leaves its safe region the mobile device has to reevaluate the query, necessitating communication with the server.
Knowing when and where the mobile device will leave a safe region is widely known as a difficult problem.
To solve this problem, we propose a novel method to monitor the position of the query over time using a linear function based on the direction of the query obtained by periodic monitoring of its position.
Periodic monitoring ensures that the query is aware of its location all the time.
This method reduces the costs associated with communications in client-server architecture.
Computational results show that our method is successful in handling moving query patterns.
