| Abstract | This paper proposes a model for the management of virtual radio resources, considering different assumptions on terminals' Signal-to-Interference- plus-Noise Ratio. The model has two main components: estimation and allocation of the available resources. In the former, a technique for obtaining probability functions for the network throughput based on the available radio resources is introduced; in addition, three approaches for estimating the network capacity, other than a general one, are proposed, i.e., optimistic, realistic, and pessimistic. In the latter, a portion of the estimated network capacity is allocated to each of the services of Virtual Network Operators (VNOs). Meeting the Service Level Agreements (SLAs) in addition to increasing the efficiency of resource usage are the key objectives in resource allocation. The results for practical scenarios show that the cellular network capacity can vary from 0.9 Gbps in the pessimistic approach up to 5.5 Gbps in the optimistic one. Moreover, the effect of this capacity variation on the allocation of the virtual radio resources to the VNOs with different SLAs is also studied. Finally, the isolation of the service classes and the VNOs by means of virtualisation of radio resources are clearly demonstrated through numeric results. |

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.
