Even though, hard decision decoding algorithm is computationally simple, its BER performance is not appreciable. Devising soft decision decoding algorithms which are simple and good in BER performance requires comparison of probabilistic and log domain methods. Towards this, a code word is generated through modulo(2) addition between message bits and generator matrix. After Binary Phase Shift Keying (BPSK) modulation the AWGN noise is introduced to the modulated code word. BER performance is computed by comparing the message decoded by soft and hard decision algorithms with the transmitted message. The experiment is conducted in MATLAB. Soft decision decoding algorithm in log domain provides better BER performance than hard decision decoding algorithm regardless of the SNR level.","PeriodicalId":123908,"journal":{"name":"2015 IEEE International Advance Computing Conference (IACC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126753298","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}

Secured access to these mobile nodes is a major issue, since these devices are most widely used in our day to day life due to their diverse capabilities like online transactions processing. Designing a reliable authentication technique for users of these mobile nodes with minimum delay incurred for the authentication process is the most vital and challenging task, so that only legitimate users can access their personal data and also communicate with the other mobile devices in the network. In this paper we present an approach for authentication of the Mobile users with minimum time delay incurred for authentication process, which is well explained with a scenario of setting up a call session during an emergency, unlike traditional techniques and hence reducing the average delay caused due to setting up a call session after authenticating the user. Performance valuation indicate that this approach achieves a reliable security for nodes with a minimum time overhead.","PeriodicalId":123908,"journal":{"name":"2015 IEEE International Advance Computing Conference (IACC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121882643","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}

It exploits the special properties of the numbers of the form 2<sup>n</sup> ± 1, and extends the dynamic range of the present triple moduli {2<sup>n</sup> - 1, 2<sup>n</sup>, 2<sup>n</sup> + 1} based systems. The proposed moduli set has a dynamic range that can represent upto 5n - 1 bit numbers while keeping the moduli small enough and the converter efficient considering computation required.

These images have high spatial resolution and hence are very high dimensional. Each scan consists of more than one hundred thousand voxels. All of the scanned voxels are not activated for every stimulus. Therefore, finding the informative voxels with respect to stimulus becomes a prerequisite for any machine learning solution using fMRI data. The specific problem attempted to be solved in this paper is that of decoding cognitive states from multiple-subject fMRI data. Decoding multiple-subject data is challenging owing to the difference in the shape and size of the brain of different subjects. A Genetic algorithm based technique is proposed here for selection of voxels that capture commonality across subjects. Some popular feature selection techniques are compared against Genetic algorithms. It is observed that feature selection using Genetic algorithms perform consistently and predictably better than other techniques.","PeriodicalId":123908,"journal":{"name":"2015 IEEE International Advance Computing Conference (IACC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123394765","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}

When source data sets are large (velocity, variety, veracity) traditional ETL (Extract, Transform, Load) is time consuming process. This paves path to extend traditional data management techniques for extracting business value from big data. This paper extends the hadoop framework for performing entity resolution in two phases. In phase 1 MapReduce generate rules for matching two real world objects with similarities. The more the similarity, the objects are similar. Similarity is calculated using domain dependent and independent Natural language processing measures. In Phase 2 these rules are used for matching stream data. Our proposed approach uses 13 semantic measures for resolving entities in stream data. Stream data such as tweets, messages, e-catalogues are used for testing the proposed system.","PeriodicalId":123908,"journal":{"name":"2015 IEEE International Advance Computing Conference (IACC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130520188","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 critical concern in ad hoc routing is routing which is handled via various routing solutions. This paper focuses on improving the I-AODV routing by considering V2V and V2I communication. The I-AODV (Infrastructure based AODV) is routing protocol that facilitate communication among vehicles through RSUs and is broadcasting in nature. This paper discusses prediction based multicasting which aids in reducing delay and improves other performance metrics. Broadcasting technique does not utilizes network resources which makes the network inefficient thus reduces throughput of the network, applying multicasting solves the purpose of proper utilization of resources as well as prediction technique helps in improving localization overhead. This technique improves the network performance metrics such as end-end delay, throughput, fuel emission, packet overhead and Packet Delivery Ratio.","PeriodicalId":123908,"journal":{"name":"2015 IEEE International Advance Computing Conference (IACC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122294494","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}
