| Abstract | The increasing demand for application oriented network Quality of Service (QoS) along with anywhere, anytime paradigm is the major driving force behind recent development in mobile devices. Highly dynamic scenarios such as tracking and monitoring of fast moving vehicles, remote healthcare of patients with diverse location profiles require vertical handover to maintain network connectivity. This need to provide seamless connectivity across multiple wireless access solutions resulted in evolution of Media Independent Handovers (IEEE 802.21). With the exponential increase in number of mobile devices with ability to switch across the networks, congestion control has emerged as a critical challenge for all network planners and service providers. This paper introduces an intelligent, congestion aware and media independent handover mechanism for the 4G heterogeneous wireless network. The algorithm embeds device intelligence in terms of making handover decisions when network congestion is sensed by the communicating nodes. The decision parameter to select destination network for handover is minimum congestion keeping other QoS parameters within the application specific acceptable limits. The improvements achieved are in terms of reduced latency and increased bandwidth in all situations and in addition to better performance in terms of load, power and cost. |

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.
