| Abstract | Increased wireless network intelligence and interference awareness enabled by cognitive radio can lead to improved spectrum utilization and network performance. Using a cognitive radio platform developed by Communication Research Centre Canada (CRC), in this work we propose and implement a novel Dynamic Channel Selection (DCS) algorithm for a network of sectorized WiFi cells. The proposed algorithm leverages the ability of underlying cognitive radio platform to continuously monitor and identify WiFi interference sources and relieves the network operator of having to manually configure and update the channels across the network. The algorithm's performance is evaluated using field experiments in both rural and urban environments which demonstrate significant improvement in terms of spectrum efficiency as well as robustness to variations in the interference. The main contributions of this work include the proposed DCS algorithm as well as offering a prime example of cognitive radio's potential in practical deployments. In addition, an overview of the CORAL platform summarizing its major components and capabilities is provided. |

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.
