| Abstract | In environments with non-uniform user density and correlated slow fading, the Poisson Point Process (PPP) model fails to capture the distribution of aggregate interference. One way to overcome this issue is to divide the deployment area into multiple disjoint clusters and describe the interference from each cluster using a PPP with cluster-specific PPP intensity and pathloss model. Obviously, too few clusters do not describe the distribution of aggregate interference accurately, while on the other hand, too many clusters incur high computational and storage overheads. In this direction, we propose to divide the area according to a hierarchical clustering algorithm which uses the Akaike Information Criterion to balance between complexity and accuracy. The algorithm can be useful for database-assisted spectrum access. It allows a database to assess the interference between systems (overlapping in spectrum but not in space) in a low-complexity manner. |

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.
