As more number of users are adopting cloud data services different types of threats are troubling them. In such scenario available Cloud Service Provider's security services may seem insufficient to keep user's data safe. User level security mechanism helps to improve security and user's trust in adopting the cloud data services. In our system we have implemented online data encryption mechanism. It is used at user level in which data to be uploaded to cloud storage is encrypted at the time of uploading. Online data encryption helps to fasten the process and saves user's time. To provide better data access control we have used a strong data security technique in which user's data identification credential and salt is used. Data identification credential, partial element of cipher key, is outsourced to cloud for further use in data decryption process. Decryption process is performed at the user level with the help of salt and one time password. In this system user is kept free from key storage and management task as well as it incorporates advanced and more secured technology of containers to store data in cloud. This paper incorporates the detailed analysis of results obtained.","PeriodicalId":442547,"journal":{"name":"2017 Fourteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122669431","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}

Proposed research presents an image enhancement method, named CLAHE-HWT derived from its existing CLAHE-DWT, which combines the Contrast Limited Adaptive Histogram Equalization (CLAHE) with Hybrid Wavelet Transform Type I (HWT I) wavelets. The method includes, the original image is decomposed into low-frequency and high-frequency components by HWT I. Then, the low-frequency coefficients is enhanced using CLAHE and the high-frequency coefficients kept unchanged to limit noise enhancement. Finally, the image is reconstructed by taking inverse HWT of the new coefficients. In order to counteract over-enhancement, the recreated and original images are averaged using an originally proposed weighting factor. Two orthogonal transforms combine to form a hybrid wavelet. Here different orthogonal transforms are used like Kekre, Walsh, Cosine, Hartley and Haar in 5 × 4 combinations total 20 hybrid wavelets of type I. This research compares all the 20 combinations of HWT I to find out the best combination of HWT with CLAHE. Experimental results demonstrate CLAHE-HWT shows better results for noise depression and avoid over enhancement.","PeriodicalId":442547,"journal":{"name":"2017 Fourteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115047223","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}

Multiple input multiple output-Orthogonal frequency division multiplexing (MIMO-OFDM) is extensively used in current and next generation broadband wireless communications to yield a high data rate of transmission and spectral efficiency over the multipath fading channels. The MIMO-OFDM systems has a major drawback as is it suffers from high peak-to-average power ratio (PAPR) which in turn requires designing of efficient power amplifier (PA), in order to maintain a wider linear region for preventing signal clipping, which therefore increases hardware complexity and power consumption. The various PAPR reduction algorithms have been developed which provide a maximum PAPR reduction ranging from 0.5 to 6 dB. The maximum SNR loss after applying a Beamforming technique is reported around 0.2 dB with BER of around 10−4 to 10−6. In the current work. Performance of PAPR analysis and reduction algorithms for beam-forming techniques include Maximum Ratio Transmission (MRT), Equal Gain Transmission (EGT) and receive combining techniques Maximum Ratio Combining (MRC), Equal Gain Combining (EGC) for MIMO-OFDM system is evaluated and reported. Measurement of MIMO-OFDM is done in terms of BER, PAPR reduction, Signal to Noise ratio (SNR) with two major PAPR reduction scheme Selective Level Mapping (SLM) and Partial Transmit Sequence (PTS).","PeriodicalId":442547,"journal":{"name":"2017 Fourteenth International Conference on Wireless and Optical Communications Networks (WOCN)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123969493","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}
