| Abstract | The proposed compression mechanism in this paper has been researched plainly in mobile phone that uses Android operating system. The aim of this proposal is to optimize the maximum character capacity of SMS body. Every character in SMS is mostly encoded in 7 bit and the maximum capacity of one SMS is only 1120 bit. Those SMS characteristics require a very efficient compression method to compress SMS Arithmetic coding is a compression mechanism that works by converting a data message to a real code number between 0 and 1. Arithmetic coding provides nearly optimal data compression. However, it requires additional memory space in compressed data to save arithmetic coding probability table for decompressing the compressed-data. Besides, it requires high precision and effective encoder-decoder to calculate and represent its code number it. In very limited data space like SMS, the need of additional memory space to save arithmetic coding probability table is inefficient. It will make the compressed-SMS size bigger than the original SMS (uncompressed SMS) size.Based on the research, the compression ratio of proposed compression mechanism is vary depends on the content of SMS. The average compression ratio of proposed compression mechanism is 71%, while the maximum compression ratio is able to reach less than 25%, i.e. 500 character SMS can be compressed to 121 character SMS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
