Recently more and more people focus on continuous K-Nearest Neighbor (CKNN) query processing over moving Objects in Road Networks. A CKNN query is to find among all moving objects the K-nearest neighbors (KNNs) of a moving query object during a period of time. The main issue with existing methods is that moving objects change their locations frequently over time and if their location updates cannot...
NETCONF is a new standard network configuration protocol. For further research we have developed an open experimental platform for NETCONF protocol, BUPT-NEP (BUPT NETCONF Experimental Platform). Moreover, based on the experimental platform some significant technologies, such as data filtering, data storage and so on, are considered. This paper gives a detailed introduction of the tree data model...
With the increasing popularity of wireless sensor network and GPS technologies, uncertain data as a new type of data bring new challenge for the data processing methods. Data broadcasting is an effective means for data dissemination in mobile computing environment. Definition of the mean uncertainty ratio of data is presented and a broadcasting scheme UDBS is proposed for uncertain data dissemination...
