GML, a geographic information coding standard, has been widely used in WebGIS, heterogeneous GIS data sharing, integration, and interoperation. However, its features of large amount of redundancy inherited from XML file structure and geographic information system make a serious obstacle in WebGIS applications. According to the characteristics of GML, a data stream-based compression algorithm GDSC...
The paper surveys some relevant issues related to data management in pervasive environments. Particularly, it focuses on the compression of semantic annotations for building so called Semantic Web of Things. An approach is proposed to achieve good compression ratios, to maintain compression effectiveness and finally to query compressed data without requiring expensive decompression phases. Experimental...
As XML has become the standard of data exchange and express of Internet and e-commerce, it is being more and more widely used, while XML is a kind of self-described language, with a large number of redundant structural information, so that is the hot study now on how to use XML data stream to be reasonable and efficient. The existing compression techniques of XML require two-pass scan on data, which...
Network configuration (NETCONF) is a widely used protocol to deploy configuration of network devices. NETCONF uses different transport layer protocols like secure shell (SSH), simple object access protocol (SOAP), or blocks extensible exchange protocol (BEEP) (IETF RFCs 4742 through 4744), and assumes availability of a high bandwidth network for successful configuration deployment. In a dynamic MANET...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
