| Abstract | In this paper, we propose a mechanism to provide a fine-grained end-to-end QoS guarantee for a mobile node handover in wireless environment. Other than selecting an access point to re-associate, we also consider the QoS status of the upper-link access router. We use information from IEEE 802.11e to obtain the current load of each access point, and information from IEEE 802.11k packets to obtain a list of neighbor access points to reduce latency in scanning process. For the network-layer QoS, we assume the Differentiated Service (DiffServ) functions on each access router. In order to reduce packet loss and latency in the network-layer handover, we consider the Fast Handovers for Mobile IPv6. We proposed a modification in router advertisement message to include DiffServ status of each AR. The mobile node in our proposed model then calculates scores of each access point and selects a new access point that has the maximum scores based on both the network-layer status and the link-layer traffic load. |

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.
