Anomaly detection technique play an extraordinary role in the Intrusion Detection System (IDS) for its ability to detect novel attacks. To overcome the high-dimensionality problem the anomaly detection cursed of, we propose a novel Meta-Heuristic-based Sequential Forward Selection (MH_SFS) feature selection algorithm, which can be generally implemented in anomaly detection system. It is an improvement...
The adaptive filtering algorithm Based on the current statistical model is the common method in maneuvering targets tracking. Aiming to improve the performance of the traditional filtering algorithm Based on current statistical model, a kind of new algorithm is put forward. At last, simulation study is made to prove its better performance. The improved algorithm not only increases the dynamic range...
Our measurements on production data center traffic together with recently reported results suggest that data center networks suffer from long-lived congestion caused by core network over subscription and unbalanced workload placement. In contrast to traditional traffic engineering approaches that optimize flow routing, in this paper, we explore the opportunity to address the continuous congestion...
In this paper, we propose a network-engineering (NE) approach for improving the availability of light paths over WDM networks. By rearranging the availability of links, the average availability of light paths can be improved without sacrificing performance in terms of blocking probability and investing extra capital expenditures (CAPEX) and operational expenditures (OPEX).
Hot trace building plays an important role in enhancing the performance of dynamic binary translators, since in most cases 10% of code takes 90% of execution time of the whole program. Hot traces can promote the code position to make better the locality of the code, therefore programs can achieve a better performance. Thus how to build qualified and long hot traces is the key point. Considering the...
Web service composition is an important technology in domain of Web service. It provides an effective solution to complex Web application. In this paper, a new composition algorithm of semantic Web service based on QoS is proposed, which is concerned with the effect of some non-functional factors of service composite quality and the satisfaction with service composition. Experiments are carried out...
In traditional dynamic binary translation (DBT) systems, poor profile information at runtime limits the manner of optimization. Combining dynamic binary translation with static analysis brings an opportunity to improve the runtime performance. Once the source image has been executed, the profile information and target code will be saved, which are available at next runs. Moreover, optimizations will...
To improve the viability of hypersonic vehicle in the dynamic environment, the study of real-time trajectory planning has a great value. The high speed of the vehicle determines a higher planning speed. The current level of airborne digital computer determines a very small memory and computing time. All of the limits make the planning more difficult. The viable strategy and the algorithm named improved...
