| Abstract | Recently, the issue of energy efficiency in wireless networks has attracted much research attention due to the growing concern on global warming and operator's profitability. We focus on energy efficiency of base stations because they account for 80% of total energy consumed in a wireless network. In this paper, we intend to reduce energy consumption of a base station by dynamically activating and deactivating the modular resources at the base station depending on the instantaneous network traffic. We propose an online reinforcement learning algorithm that will continuously adapt to the changing network traffic in deciding which action to take to maximize energy saving. As an online algorithm, the proposed scheme does not require a separate training phase and can be deployed immediately. Simulation results have confirmed that the proposed algorithm can achieve more than 50% energy saving without compromising network service quality which is measured in terms of user blocking probability. |

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.
