| Abstract | With the recent advances of mobile computing devices with communication capabilities, virtual environment walkthrough and real-time streaming movie playback for mobile devices has opened a new class of 3D virtual environment exploration based applications such as virtual guides and malls, online gaming, training and monitoring, just to name a few. The challenge lies in how to provide a rich and detailed 3D virtual environment on thin mobile devices that are known for their lack of proper resources to process large scale 3D geometric data. In this paper, we focus on defining a new approach to remote rendering and interactive visualization of 3D virtual environments on thin mobile devices such as PDAs and cell phones. To this end, we propose efficient end-to-end streaming and rate control protocols to support the requirements of bandwidth-demanding multimedia systems. The main purpose of our proposed rate control scheme is to achieve both high end-to-end throughput and low frame rate Âșuctuation in order to adapt data traffic to the frequent changes of the bandwidth and error rate, mainly due to the nature of wireless networks. We discuss the design of our proposed streaming and rate control algorithms, and report on the their performance evaluation using an extensive set of simulation experiments. |

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.
