Flash memory is being rapidly deployed as data storage for mobile devices. With its capacity increasing and price dropping, flash memory will finally take the place of magnetic disk. It is possible for us to consider running a database system on the flash computing platforms. Therefore, this requires an efficient index structure to locate a particular item quickly from a huge amount of database records...
Many hybrid index structures have been proposed to answer Spatial-Keyword (SK) queries in geographic information system (GIS). To the best of our knowledge, however, few works focus on querying approximate keyword in GIS efficiently. In this paper we propose gR*-tree for Approximate SK queries- ASK queries, whose objective is to find the spatial objects with their textual attributes similar to the...
Flash memory, especially NAND flash memory, is being rapidly deployed as data storage for mobile devices such as mobile phones, digital cameras and PDA's. With its capacity increasing and price dropping, Flash memory has been installed in many portable computers instead of magnetic disk for its light weight, small size, physical stability and low power consumption. We may expect that Flash memory...
The Datagram Congestion Control Protocol (DCCP) was designed to provide congestion control for unreliable applications, such as voice-over-IP and IPTV. But the current congestion control mechanisms of DCCP do not have the ability to support Quality of Service (QoS) features. This paper aims to design an end-to-end QoS-aware congestion control mechanism for DCCP based on theory. In particular, we design...
