| Abstract | In this paper, we investigate a mobility procedure for mode II personal/portable TV Band Devices (TVBDs). There is a possibility of forced termination probability (FTP) or blocking probability (BP) in the TV White Space (TVWS) while portable TVBDs are moving. This is because the availability of TVWS is dependent on the location and time schedule of licensed devices and other unlicensed networks. In order to support mobility efficiently, the concept of multiple geo-location capability of the FCC's rule is introduced. The mobility of multiple geo-location capability is evaluated compared to single geo-location capability. In addition, we investigate on which multiple access technique is better for portable TVBD networks considering a mobile TVWS environment. To reduce the outage probability of Orthogonal Frequency Division Multiple Access (OFDMA) which could not obtain diversity from soft handover, we propose a handover procedure based on subcarrier selection scheme. Simulation results show that the multiple geo-location capability enhances the mobility in terms of FTP, BP and delay. It is also shown that the proposed handover procedure using the multiple geo-location capability reduces the outage probability by obtaining the selection diversity. |

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.
