| Abstract | In a B3G/4G wireless communication system, the users will connect to the network using one of several available radio access technologies. In this paper, we proposed a Q-learning based algorithm for terminals' independent access network selection with the aim of improving the resource utilization and providing the best quality of service with respect to the wireless environment status, network performance and user' requirement. In particular, for the first time we introduced the concept of low-carbon as one of the evaluation indicators of wireless communication performance, in order to reduce the power consumption and achieve a balance between quality and consumption. The proposed scheme is based on the concept of cognitive network, which has been proposed recently by the motivation of complexity, heterogeneity and reliability requirements of tomorrow's network and the cognitive pilot channel used in it. The performance of the access network selection algorithm is shown in the simulation and it can be seen that this algorithm significantly reduced the blockrate and power consumption as well as increased the throughput compared with random accessing approach. In future work, we will continue to research on the effective access network selection algorithm and try to introduce the low-carbon indicator to other aspects of the wireless communication system. |

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.
