| Abstract | This paper focuses on a methodology for the dynamic allocation of embedded resources apt to satisfy requests of service with constraints of Quality of Service (QoS). Given a set of services provided by an embedded system, this methodology suggests how to determine the best match between a requested service and the set of Embedded subSystems (EsSs) able to provide that service. The selection of EsSs is carried out on the basis of the results of an a priori evaluation of the performances of service execution and of the availability of the single embedded resources. Moreover, the proposed methodology defines some guidelines to dynamically schedule and thus to assign the execution of the services to the chosen EsSs. With regard to the selection process this methodology benefits from both the content- and the collaborative-based filtering methods. To evaluate its consistency it has been implemented in a testing framework, named BIOS, that includes a repository of services, of service providers (i.e. of EsSs), of evaluation outcomes of the performances of each EsS in carrying out its own services, of an engine for the dynamic selection of the EsSs able to satisfy the requirements of a given service and of a container of Real-Time Operating Systems (RTOSs) able to efficiently schedule and to assign the execution of the requested services to the chosen EsSs. Considering state-of-the-art services provided by Body Sensor Network (BSN) subsystems, the hybrid solution proposed for the selection process has been tested and it has shown better results in comparison to the content-based filtering technique. |

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.
