| Abstract | Given the highly dynamic nature of wireless ad hoc network, routing is one of the most challenging tasks. Among the routing protocols that are in the process of normalisation is AODV (Ad hoc on demand Distance Vector). AODV is a reactive source based on routing protocol whose performance is very sensitive to several fixed parameters, such as. ACTIVE_ROUTE_TIMEOUT, HELLO_INTERVAL, MY_ROUTE_TIMEOUT, NET_DIAMETER, RREQ_RETRIES, .... In this paper we propose an adaptive version of AODV (A^2ODV) where the protocol regularly adapts its routing decision to the state of the behaviour and the state of the network. In A^2ODV each node maintains an estimation of the reliability as well as an expected residual uptime of its interfaces. A route is characterized by two metrics: (1) reliability defined as the product of its constituent links; and (2) Route residual lifetime estimated by the residual lifetime of its weakest link. Route selection is a function of these two metrics. Simulation shows that A^2ODV clearly outperforms AODV with respect to packet delivery ratio and overhead traffic. |

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.
