| Abstract | This paper deals with fairness among stations (STAs) in multi-rate wireless local area networks (WLANs). If STAs compete for channel access according to IEEE 802.11 distributed coordination function, they have comparable opportunity of channel access, regardless of transmission rate. Accordingly, high-rate STAs achieve throughput similar to low-rate STAs, which is well known as performance anomaly. To mitigate this problem, we propose a hybrid solution combining contention window control with frame aggregation. By controlling contention window of each STA, the proposed mechanism assures higher channel access opportunity for high-rate STAs, without resulting in the unnecessary high collision probability. At the same time, it controls the frame aggregation factor based on the transmission rate of each STA, in order to tightly assure perstation fairness in terms of channel occupation time. To validate the proposed mechanism, we perform intensive simulation which confirms its outstanding performance in terms of throughput, fairness, and utilization. |

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.
