Because much interest in spatial database in cloud computing has been attracted, studies on preserving location data privacy in cloud computing have been actively done. However, since the existing spatial transformation schemes are weak to proximity attack, they cannot preserve the privacy of users who enjoy location-based services from the cloud computing. Therefore, a transformation scheme for providing...
GML (Geographic Markup Language) is a markup language presented as exchange standard for geographic information by the OGC (Open GIS Consortium). In spatial network databases, studies on GML can be divided into parsing, storing and retrieval of GML documents. Among them, the storage of GML documents is essential for their efficient retrieval. However, there is little research on storing GML documents,...
For wireless sensor networks (WSNs), how to design routing protocols is very important to gather data efficiently so that the life of the network can be prolonged. A usual concept to collect data by a sink node is to transfer data from sensor nodes to the sink node by multihop. However, it gives rise to two problems. The first one is that core sensor nodes being more frequently used to gather data...
