| Abstract | In Wireless Sensor Networks, the preloaded program code and data on sensor nodes often need to be updated due to changes in user requirements or environmental conditions. Sensor nodes are severely restricted by energy constraints. It is especially energy consuming for sensor nodes to update code through radio packages. To efficiently update code through wireless radio, we propose an algorithm, Reprogramming with Minimal Transferred Data (RMTD), to find the optimum combination of copying from the old code image and downloading from the host machine to minimize the number of bytes needed to be transferred from the host machine to a sensor node. Our experiments show that, for small code modifications, RMTD reduces the number of bytes transferred by 93.25% over the existing Rsync-based algorithm. For normal code changes, RMTD shows an improvement of 59.82% in average. |

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.
