| Abstract | In this paper, we study rate allocation for a set of end-to-end communication sessions in multi-radio wireless mesh networks. We propose cross-layer schemes which can jointly solve rate allocation, channel assignment, routing, scheduling and power control problems in multiple layers. Specifically, a Linear Programming (LP) based scheme is presented to compute end-to-end rate allocation with the goal of maximizing network throughput. As simple throughput maximization may lead to a severe bias on rate allocation, we take fairness into consideration based on a parameter named Demand Satisfaction Factor (DSF), and two fairness models, a simplified max-min fairness model and the well-known proportional fairness model. We propose LP-based and Convex Programming (CP) based schemes to compute fair end-to-end rate allocation. Our schemes can provide upper bounds on achievable network throughput and max-min DSF values. Numerical results show that our proportional fair rate allocation scheme achieves a good tradeoff between throughput and fairness. |

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.
