In the existing service selection models, there is not a good one for SaaS system. In view of the characteristics of multi-tenant in SaaS system and the perspective of ensuring the tenants' enthusiasm, this paper puts forward a QoS-constrained service discovery model based on intelligent agent, as well as a service selection algorithm based on tenant level. Extensive experiments have been conducted...
The explosive growth of data increases the burden of storage systems. At the same time, the redundant data result in a waste of storage space and an increase in cost. Data deduplication is urgently required to alleviate these problems. Similarity detection is very critical to the performance of data deduplication. This technique reduces memory consumption and improves the data deduplication ratio...
Channel mismatch has become a serious limit to further improve the anti-jamming performance on satellite navigation antenna arrays receivers. Consistency degree of each channel could directly determine the anti-jamming performance. In order to analyze and confirm the channel consistency indexes, this paper analyzes the impact of channel mismatch on interference cancellation ratio (ICR), firstly. According...
During recent years, Peer-to-Peer (P2P) Content Sharing Networks (CSNs) have intrigued researchers to measure and analyze them for the dominant proportion of P2P traffic volume and wide applications of the sharing platform. However, to the best of our knowledge, most of the measurement tools have not been updated under the current situations of P2P CSNs. In this paper, we develop an enhanced measurement...
Aiming at reducing the overload of cable television information and the difficulty to pinpoint users, this research employs the directed preview method of CATV's live programs which is grounded in labels. Long-term and short-term models of users' viewing behaviors and models of period preference are constructed accurately and can multi-dimensionally describe users' viewing behaviors. Based on labels,...
