Mobility model and call admission control (CAC) algorithm are important for wireless mobility networks. This paper firstly sets a practical mobility model, and then presents a novel measurement-based CAC algorithm utilizing time series analysis under the random model. The algorithm updates the reservation threshold by directly forecasting the next possible number of handoff dropping calls, using ARMA...
The traditional data mining algorithms behaves undesirable in the instance of imbalanced data sets, as the distribution of the data sets is not taken into consideration when these algorithms are designed. This paper describes the Naive Bayes classification mechanism, and then points out that, random re-sampling methods not to be able to improve its performance. A negative-case-pruning Naive Bayes...
Traditional infrared detection system has small viewing field and low scanning speed, a new all-directional IRST system with high scanning speed is designed, which quickly images the whole spherical airspace on the infrared sensors by the reflector circumrotating in pitching and azimuth with high speed. The real-time processing system for high speed input images is constructed based on the processor...
