| Abstract | In the heterogeneous cellular network, each mobile station perceives different channel gains to different base stations. Therefore, it is important to associate a mobile station with the right base station with transmit power control so as to achieve substantial improvement in spectrum-efficiency and energy-efficiency. Despite its importance, the problem that maximizes the overall system revenue with minimum total transmit power consumption through joint BS association and power control has remained largely unsolved for the large-scale heterogeneous cellular network, mainly due to its non-convex and combinatorial nature. To solve this problem, this paper first proposes a single-stage formulation that captures two interactive objectives, i.e., the maximization of overall system revenue and the minimization of total transmit power consumption. The single-stage optimization problem is then efficiently solved by the proposed POSEM algorithm based on the theory of coalition formation game and the idea of simulated annealing. Finally, our analysis shows that the proposed algorithm is guaranteed to converge to the global optimal solution fast. |

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.
