| Abstract | Ad hoc network is expected to play a major role in future wideband wireless access to the Internet. The dual mode system that multi-hop network overlaid with a cellular structure is more and more attractive for researchers. However, routing is important for such networks due to the dynamic nature of network topology and the resource constraints. To maximize the resource utilization and minimize the network transfer delay along the path, the shortest path with minimum hops approach is often adopted. However, the quality of wireless channel among the mobile nodes is time varying due to fading, shadowing and path loss. Considering adaptive channel coding and modulation scheme, the channel state can be characterized by different link throughput. In this paper, a channel adaptive routing (CHAR) is presented. The CHAR transform link throughput into the channel quality factor and finds the shortest routing according to the channel quality measure. Simulation results show that the proposed routing may reduce the average transfer delay and increase the packet deliver rate. |

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.
