| Abstract | With the advances in wireless communication technology and artificial intelligence, robots are gradually being introduced as part of our life. Previous research proposed a SIP-enabled Surveillance Patrol Robot (SSPR), which tracks a moving object actively and informs the householder of such security alarm. However, the underlying signaling protocol for communication and data streams suffer from the network address translation (NAT) traversal problem as most peer-to-peer (P2P) applications. NAT is a commonly adopted technique to share one public IPv4 address among several hosts located behind a NAT device for alleviating the exhaustion of IPv4 address. NAT devices typically block session requests originating from outside, prevent the establishment of peer-to-peer (P2P) sessions and cause NAT traversal problem. This study proposes WANTS, a WiFi Assisted NAT Traversal Scheme for SSPR. When SSPR is activated, it retrieves the topology information from a server to choose the candidate access point (AP) for handoff. Then SSPR uses the collected network context information to assist its NAT traversal procedure after handoff. Experimental results confirm that WANTS reduces not only connectivity check delay but also protocol messages as compared to the Interactivity Connectivity Establishment (ICE), which is the most acknowledged approach to creating a session across NATs. |

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.
