| Abstract | With the rapid development from mobile computing toward ubiquitous computing, more and more users access to wireless network service at anytime anywhere with various kinds of portable mobile devices. To effectively support a group of mobile devices move together, the network mobility basic support protocol (NEMO-BSP) has been proposed. It defines a mobile network as one or more mobile router (MR) with one or more IP subnets each with some mobile network nodes (MNN). Each MNN acquires its network prefix from the MR and accesses the Internet through MR. Mobile network could be nested as one mobile network moves into the scope of another mobile network. However, routing path becomes very long as the nested level increases. As a consequence, it also increases the overhead of the IP tunneling. In this paper, we propose a Hierarchical Mobile Router architecture, called HMR-NEMO, to improve the routing performance as well as reduce the IP tunneling overhead of NEMO for nested mobile networks. In HMR-NEMO, the top level MR acts as a MAP such that packets from Home Agent (HA) or Corresponding Node (CN) of MNN could be directly tunneled to the top level MR and then tunneled to MR. Furthermore, binding update could also be suppressed at top level MR. Our simulation results show that HMR-NEMO significantly reduces the IP tunneling overhead and binding update overhead while improves the routing efficiency. |

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.
