First of all, we provide a rigorous analysis of the impacts of channel degradation on block ciphered systems. We show that the overall channel can be modeled as a Finite State Markov Chain (FSMC) with symmetric channels associated in each state, whose underlying non-coherent Shannon capacity is derived and computed. Despite Eve's efforts in modifying her linear crytanalysis given the intercepted noisy ciphertexts, there is still a non-negligible probability of having possible failures in her attack. We essentially create a wiretap channel in application layer that is a degraded version of the main channel and measure security of the system in terms of secrecy capacity and show that it depends on the deliberately introduced bit error rate. In addition, Alice can accordingly adjust cross over probability of the channel to maximize secrecy rate. This secrecy rate can be achieved by wiretap channel coding over multiple frames in application layer if the delay in system is bearable.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114383810","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}

Often classification of more than two classes is broken down into a group of binary classification problems using the one-versus-rest or pairwise approaches. For each binary classification problem, feature selection and classifier design are usually conducted separately. In this paper, we propose a new multitask learning approach in which feature selection and classifier design for all the binary classification tasks are carried out simultaneously. We consider probabilistic nonlinear kernel classifiers for binary classification. For each binary classifier, we give weights to the features within the kernels. We assume that the matrix consisting of all the feature weights for all the tasks has a sparse component and a low rank component. The sparse component determines the features that are relevant to each classifier, and the low rank component determines the common feature subspace that is relevant to all the classifiers. Experimental results on synthetic data demonstrate that the proposed approach achieves higher classification accuracy compared to the conventional classifiers. The proposed method accurately determines the relevant features that are important to each binary classifier.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123795885","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}

Households or users cooperate to trade these goods, in this case, their real-time energy supplied by utility company and their stored energy in order to minimize consumption cost. Difference in pricing mechanisms adopted by utility companies that serve the locality gives incentive for users to trade real-time energy. Households schedule their storage devices to be charged during low-price off-peak hours and sell the surplus stored energy to neighbours during peak hours to generate additional income. This creates a trading environment or a market where users exchange real-time energy and stored energy at certain prices. Preference relations of users capture how energy is valued in an economy by each user. We model these preferences as a utility that is a continuous, monotonic, quasi-convex function of energy. Given a set of endowments, consumption profiles and energy prices in the market for each user, we show that a market is created where real-time energy and stored energy are exchanged between users and such an exchange takes place at the competitive equilibrium. We analyze a simple two-user two-good exchange economy market to illustrate the concepts discussed above and prove that the trading prices of the goods in the market regulate themselves in such a way that trading results in reduced costs for both users.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125612439","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}

However, combining cooperative communication and energy harvesting in a network requires an efficient and a practical relay usage scheduling scheme to maximize the overall packet delivery ratio. This paper considers a wireless sensor network with energy harvesting and cooperative communication, and proposes a practical scheme that maximizes the packet delivery ratio of the system. The results show that our scheme provides almost the same performance of the threshold based scheme (state-of-the-art scheme) using the same system parameters. Compared to the threshold scheme that has a tunable parameter (threshold value) for each set of system parameters, the results show that our scheme does not require any tunable parameter to maximize the performance. In the threshold based scheme, if one of the system parameters changes, the sensors need to tune the threshold level at a new value to maintain the maximum performance. Tuning the threshold at a certain value requires simulating the system at different threshold levels to get that tunable value. This is not easy and might not even be practical to implement especially in networks of thousands of sensors with unstable parameters. So, no need for any tunable parameter makes our scheme easier and more practical to be used. Also, it makes our scheme more flexible to adjust the performance of the source and relay to ensure fairness between them.","PeriodicalId":268095,"journal":{"name":"2013 47th Annual Conference on Information Sciences and Systems (CISS)","volume":"306 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121278732","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}
