| Abstract | Since many users share limited wireless resources in wireless networks, it is important for resources to be allocated among users in a fair and efficient manner. The scheduler at the base station is responsible for allocating resources to users. Many researchers have developed efficient scheduling algorithms but most these algorithms were designed separately and independently for the uplink or downlink. Because a user generally has two communication links, an uplink and a downlink, the overall satisfaction with a communication service can be formulated as the sum of the quality of the uplink and downlink services. Hence, the poor quality of either link can degrade the overall quality of service. This paper proposes a joint proportional fair (PF) scheduling algorithm for wireless networks, where the scheduling of the uplink and downlink is done jointly so that the bandwidth can be shared efficiently and fairly between the uplink and the downlink. The paper introduces three joint scheduling algorithms: joint delay-based scheduling, joint maximum rate scheduling, and joint PF scheduling. The simulation results show that in comparison with conventional scheduling algorithms the proposed joint PF scheduling algorithm achieves a better compromise between the throughput and user fairness by adjusting the weighting factor between the uplink and downlink. |

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.
