| Abstract | We focus on downlink scheduling and resource allocation for orthogonal frequency division multiplexing (OFDM) wireless networks. From a perspective of network operators, the base station (BS) will charge the downlink users to earn revenue and pay for electricity consumption. The aim of network operators is to achieve better profits while ensuring network stability. In the context of smart grid, the BS can harvest renewable energy and store energy in order to cut down electricity cost. The challenge is that it is hard to obtain the accurate statistic knowledge of electricity price, random rate requests and renewable energy. Furthermore, we have to deal with the dynamic data rate requests from downlink users with heterogeneous quality of service (QoS) requirements. To handle the coupling between congestion control, energy consumption and radio resource allocation, we propose a pricing-based crosslayer scheduling and energy management algorithm PCSM based on Lyapunov optimization: the energy management can well regulate the electricity charging rate in case of interrupting the downlink service; the data rate pricing-based congestion control scheme collects proper revenue by setting data rate price to carry out flow control and profit maximization; the radio resource allocation can achieve adaptive allocation by using cross-layer information from the network layer as well as energy storage condition. Theoretical analysis shows that it can achieve a near-optimal performance when stabilizing the network and that its effectiveness is also validated through simulation results. |

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.
