| Abstract | In Wireless Mesh Networks (WMNs), supporting Quality of Service (QoS) to enable a rich portfolio of applications/real-time multimedia applications is foreseen to be vital for the success of next generation networking technologies. However, today's cutting edge standards are not perfectly equipped to cater to this task. These standards come with an inherent complexity and suffer from innate problems with respect to QoS provisioning. Consequently, due to the limited resource of WMNs and increasingly demand of new applications, there is a need for devising innovative routing algorithms for supporting QoS on top of the existing standards. Thus, this paper presents a cross layer relay node selection scheme for routing protocols in order to offer optimal routes to real-time applications. Distinguished from guaranteeing a certain level of performance, our QoS scheme provides differentiated priorities and service levels to application with different needs. The scheme includes two parts. In the first part, we present an application priority model to update the application/priority table from the gateway periodically. Secondly, a new routing metric combining application priority, channel busy level and hop count, is deployed to evaluate and select the best from plurality possible paths during the communication phase. Our simulation experiments confirm the superiority of the proposed scheme against a number of existing counterparts. |

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.
