| Abstract | Under complicated circumstance, random failures of wireless nodes always happen. However, some critical tasks must be running on wireless nodes to finish one job cooperatively, such as underwater data collection, forest fire sensing, and so on. Those critical tasks should running ceaselessly, and if a node failure happens, there must be a scheme to guarantee the task requirement. In response to this issue, we propose a multi-tasks migration scheme, which firstly analysis the dependency of the multiple running tasks by means of constructing a Directed Acyclic Graph (DAG), then dynamically transform those DAG tasks to interdependent and layered DAG tasks, and finally the optimal path for migration from failed nodes to healthy nodes is determined. The simulation results show that proposed scheme gives good performance to guarantee critical tasks running ceaselessly even under the situations of dynamic network workload and unknown faults. |

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.
