New intelligent Intrusion Detection Systems (IDSs) which are based on sophisticated algorithms rather than current signature-base detections are in demand. In this paper, we propose a new data-mining based technique for intrusion detection using an ensemble of binary classifiers with feature selection and multiboosting simultaneously. Our model employs feature selection so that the binary classifier for each type of attack can be more accurate, which improves the detection of attacks that occur less frequently in the training data. Based on the accurate binary classifiers, our model applies a new ensemble approach which aggregates each binary classifier’s decisions for the same input and decides which class is most suitable for a given input. During this process, the potential bias of certain binary classifier could be alleviated by other binary classifiers’ decision. Our model also makes use of multiboosting for reducing both variance and bias. The experimental results show that our approach provides better performance in terms of accuracy and cost than the winner entry of the ‘Knowledge Development and Data mining’ (KDD) ’99 cup challenge. Future works will extend our analysis to a new ‘Protected Repository for the Defense of Infrastructure against Cyber Threats’ (PREDICT) dataset as well as real network data.","PeriodicalId":103090,"journal":{"name":"2009 Seventh Annual Communication Networks and Services Research Conference","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114936904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EER amplifiers utilized in terrestrial Amplitude Modulation (AM) radio broadcast transmitters are affected by non-linear and memory effects; the proposed compensation method exploits the source of these effects in real-world amplifiers. Specifically, using a new feed forward configuration for pre-processing the amplifier input, the algorithm predicts the PA output in real-time using its realistic behavior modeled through dynamic differential equations. The compensation method implemented at the base band considers the effects created by the most critical components of the EER amplifier, i.e, band-limiting of the envelope by the reconstruction filter and a non-linear load applied at the output of the reconstruction filter. The performance improvements of the proposed method are measured by its ability to reduce Total Harmonic Distortion (THD) at the output of the system. Taking advantage of the efficient utilization of available computational resources, the feasibility of implementing this system is verified using a FPGA platform.","PeriodicalId":103090,"journal":{"name":"2009 Seventh Annual Communication Networks and Services Research Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133490655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As some networks such as UMTS (universal mobile telecommunication system) can offer a wide geographical coverage with relatively low data rate, while other networks such as WLAN (Wireless Local Area Network) can support much higher bandwidth at a local level, network selection is becoming one of the most significant challenges for the next-generation networks. In this paper we propose an efficient network selection mechanism which combines two mathematical techniques. Analysis hierarchy progress is utilized to achieve the weights of QoS factors based on the user preference, and genetic algorithm can solve the multi-objective optimization problem. As pure genetic algorithm has weak local search capabilities and low efficiency around the Pareto Optimal Solutions , it may even cannot reach the Pareto optimal solution. To solve this problem, we propose the enhanced Pareto genetic algorithm combined with Tchebycheff method, which can improve efficiency of optimization and ensure a better convergence to the true optimal network.","PeriodicalId":103090,"journal":{"name":"2009 Seventh Annual Communication Networks and Services Research Conference","volume":"536 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134290732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
