| Abstract | Seamless handoff is crucial for providing pervasive wireless access especially to support time-sensitive applications in 802.11i security enhanced WLAN, but it introduces large authentication delay to provide advanced security during a handoff. In order to reduce the authentication delay, the IEEE 802.11 work group has defined a pre-authentication scheme; however, the defined scheme works in the MAC layer and does not work in the network layer in IP routing-based multi-domain networks. In this study, the authors proposed a practical secure and fast handoff framework, called V2V, which not only extends the 802.11i pre-authentication scheme to overcome the above limitations, but also supports pre-configuration with dynamic host configuration protocol to reduce the handoff delay further. A prototype of the V2V system is implemented and the testing results show that one can reduce the overall handoff delay, including association, authentication, IP configuration and mobile IP location update, to no more than 50 ms, which can support most time-sensitive applications such as VoIP. |

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.
