Cloud computing has been increasingly gaining popularity due to the benefits such as its access capability from any location, sharing of data across multiple data centers, and the management of data storage by the service providers. Since security is still an unresolved issue in public cloud storage, business critical data can be preferably maintained in private cloud storage. It is normally built with the utilization of unused commodity machines. As storage space is limited in private cloud storage, it has to be efficiently utilized. Hence, a specialized technique known as deduplication is used to reduce the data footprint in the storage. This technique splits the file into several chunks. Chunks of different files are compared against each other to ensure only unique chunks are stored in the storage. Chunk index maintains the chunkID and the location of the actual chunk for reconstructing the file. Whenever a file is stored in the storage system, corresponding metadata is also placed along with it to facilitate the retrieval of that file. Metadata generally includes the properties of the file and the beginning location of physical block of the file. In deduplication enabled cloud storage system, since the file is stored in the form of a collection of chunks, chunk index also need to be maintained in addition to metadata. This improves the search time of a particular file. Thus, the efficiency of the chunk indexing mechanism will directly influence the file retrieval time. In order to achieve faster retrieval time, this paper proposes multi-index structure for metadata management.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"488 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131786741","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}

WSN consists of cameras, which have some local image processing and one or more central computers, where image data from multiple cameras is further processed and fused. Because of these limitations, the encoding techniques used for transmitting the image data should be efficient in order to make use of the available resources properly. A new sampling method is also introduced in the Image/video encoder of the WSN called Compressed Sensing (CS), which is the process of acquiring and reconstructing a signal that is supposed to be sparse or compressible, thus reducing the computational complexity. The image is divided into dense and sparse components by applying 2 levels of wavelet transform. The dense component uses the standard encoding procedure such as JPEG and the sparse measurements obtained from the sparse components are encoded by the techniques such as Exponential Golomb coding followed by Run-length encoding and arithmetic coding and the performances in terms of compression ratio and bits per pixel are compared. The recovery algorithm may be anyone supporting the compressed sensing technique such as OMP, POCS etc. In this work, the measurements (used in CS) and the predicted sparse components as the initial values, the projection onto convex set (POCS) recovery algorithm is used to get back the original sparse components of two levels and hence the original image by applying the inverse of transform to the dense and recovered sparse components.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131895658","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 necessity for change increases with the market demand and technology. Though there are many existing change management approaches to satisfy the normal changes, they fail to support the evaluation of dynamic changes within the business constraint based on both functional and nonfunctional behavior of the services undergone changes. Apart from this, there is no proper model that provides a legitimate manifest of the service quality parameters which are deviated from their threshold to the analyst. In order to provide a flexible environment for the Business Analyst to perform the emergency changes over the service business logic without the need of IT staff and also to evaluate changes made, we propose a Finite State Machine based evaluation methodology for web service change management. The key benefit of this approach is it primarily evaluates the functional change factors then concurrently it evaluates the non functional factors which are deviated from their threshold value. The set of quality centric change factors with their QoS measures are successfully evaluated through this approach within the expected reaction time.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131073994","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}
