| Abstract | Nowadays, the existing myriad of wireless capable devices has led to the development of numerous multi-hop routing protocols. From proactive to reactive and even hybrid routing approaches, these protocols have motivated the definition of autonomous and ubiquitous ad-hoc networks. Such networks have been idealized not only for disaster and rural scenarios, but also for an increasingly demanding social context in urban areas. However, being able to handle these networks in a large scale, still remains a challenge. Even though several routing solutions resort to clustering and hierarchies in order to limit routing information, the existing nodes' interactions are typically disregarded and mobility amongst different clusters still raises routing issues. In this work the scalability of three routing protocols will be analysed, by defining different size scenarios, while also assessing their routing performance with a mobile node moving between different clusters. Theoretical and simulation based results are presented, using twenty different possible transitions through the existing clusters. This evaluation provides an important contribution, revealing that hierarchical routing organizations' scalability is closer to what is theoretically expected, contrary to other routing solutions. Moreover, regarding the best routing performance which takes into account communities, these results motivate the further utilization of such schemes for future large scale ubiquitous networks. |

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.
