Recent research shows that multimedia resources in the wild are growing at a staggering rate. The rapid increase number of multimedia resources has brought an urgent need to develop intelligent methods to organize and process them. In this paper, the semantic link network model is used for organizing multimedia resources. A whole model for generating the association relation between multimedia resources...
The widespread deployment of Wireless LANs are underpinned by two most popular variants of IEEE 802.11 standards, 802.11b and 802.11g. The 802.11g extends 802.11b to support higher data rate via new OFDM-based physical layer, but both of them operate at 2.4GHz band and perform medium access with the same MAC protocol. When the 802.11b and 802.11g devices co-exist in the overlapping coverage area,...
Due to the short history of researches for wireless sensor network which has been emerging prominently since the early 1990s, the systemic assessment indicators and efficient evaluating methods of wireless sensor networks is still under exploring. Hereupon, the designing of systemic indicators and assessment methods inspired by the rough set theory are described in this paper to enrich the methodologies...
A novel IP quality evaluation method is proposed in this paper. Based on the analysis of the characteristics of several current mainstream IP quality evaluation metrics, advantages and deficiencies of them are summarized. The comparison indicates that due to coarse grain of classification and focusing more on common features, the definition methods of these metrics are lack of individual characteristics...
Long-term evolution (LTE) of the UMTS terrestrial radio access and radio access network is considered to ensure the competitiveness of 3GPP radio-access technology in a longer time frame. To minimize/optimize the user equipment (UE) power consumption, and further to support various services and large amount of data transmissions, a discontinuous reception (DRX) mechanism with adjustable DRX cycles...
