| Abstract | Traffic routing and gateway selection for Internet flows play a crucial role in determining the performance of WMNs. Optimal routing strategies have been derived under the assumption that the traffic demands are static and known a priori, or that can be accurately predicted. However, the effectiveness of most of the existing optimization-based routing solutions is still to be demonstrated in real-world deployments. In this paper we present a practical and robust framework for load-balanced routing and gateway selection in WMNs under variable traffic loads, which relies only on real-time measurements of network statistics. Then, we design, implement and evaluate two simple adaptive strategies to automatically select network paths and gateways for flows that dynamically arrive and depart, with the goal of achieving a high network utilization and improved load balancing. We have developed a full-fledged implementation of the proposed mechanisms as an extension of the OLSR protocol, and conducted an experimental study in a trial outdoor mesh network using video streaming traffic. Collected measurements show that our scheme can significantly increase the number of video sessions that can be supported with acceptable quality compared to traditional shortest path routing. |

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.
