| Abstract | Next generation Location-based Services (LBSs) are coined by a proactive user-interaction as well as a crossreferencing target relationship. In a proactive user-interaction, a service continuously keeps track of a user's locations and performs arbitrary actions upon entry or exit of a certain region. A cross-referencing target relationship implies that the LBS user and the target are not identical, which is the case, for instance, when a 3rd party subscribes for certain location events on behalf of the tracked user, i.e. in a Location-based Advertising scenario. In order to efficiently realize sophisticated proactive, cross-referencing LBSs, a number of challenges need to be surmounted. Unfortunately, existing research within this respect is still rudimentary and a huge potential still remains untapped. Proactive LBSs involve continuous background tracking to know the location whereabouts of a user as well as process it in order to detect useful information in the vicinity. However, this results in severe battery drainage, hence shaping the main barrier for the realization of such services. Moreover, continuously tracking a user's location raises major privacy concerns, especially in case of cross-referencing LBSs. In this paper, we present the Positioning Enabler service middleware platform which provides a set of functionalities and APIs for enabling battery-efficient background tracking of single and multi-targets in a proactive manner, enabling the realization of sophisticated LBSs based on continuous background tracking and geofencing. Furthermore, it supports 3rd party Geolocation Messaging while implementing certain location privacy measures for not invading user's privacy. The service middleware is used in the implementation of a Context-aware Polling mobile application for smart cities, FlashPoll. |

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.
