A set of distributed continual range query requests, each defining a geographical region of interest, needs to be periodically reevaluated to provide up to date answers. Processing these continual queries efficiently and incrementally becomes important for location based services and applications. In this paper, we propose an efficient incremental method for continuous range query characterized by...
A mechatronic vision system for the automatic acquisition and the monitoring of the static and the moving objects is proposed. The system recognizes the existence and the motion of relatively small objects from the background in order to report motion parameters while automatically tracking the selected object. The system consists of several relatively independent subsystems cooperating together with...
The recent technological advances in location aware, mobile and wireless devices have facilitated tracking and monitoring of moving objects. However, these capabilities require storage structures that allow the speedy access and fast retrieval of information for these objects. Therefore, there is increasing interest in storage and indexing structures based on a variety of R-trees. These tree structures...
Monitoring moving objects is one of the key application domains for sensor networks. In the absence of cooperative objects and devices attached to these objects, target tracking algorithms have to be used for monitoring. In this paper, we present that many of the applications of moving object monitoring systems could be addressed with low-frequency snapshot-based queries. With the realization of this...
In this paper, we propose iSEE, a set of algorithms for efficient processing of continuous k-nearest-neighbor (CKNN) queries over moving objects. iSEE utilizes a grid index and incrementally updates the queries' results based on moving objects' explicit location update messages. We have three innovations in iSEE: a Visit Order Builder (VOB) method that dynamically constructs a query's optimal visit...
