| Abstract | Long-range radio can connect sensors/IoT devices without complex and costly deployment of relay nodes. However, this flexibility comes with stricter legal regulations such as maximum radio activity time per 1-hour period. Under such constraints it is difficult to provide service guarantees, which is quite paradoxical when devices are deployed for surveillance systems. The approach we propose allows devices to go “exceptionally” beyond the activity time limitation by borrowing time from other devices. The mechanism is not intended to be used on a regular basis, where a device is commissioned to always report data at a rate that makes it consuming more than the allowed duty-cycle limitation, but to offer a “last chance” solution for providing better surveillance service guarantees while globally satisfying duty-cycle regulations. The proposition has been implemented on our long-range image sensor platform, and preliminary experiments show that it can maintain the system’s consistency and keep the number of control messages small while being capable of handling sleep-wakeup behavior and dynamic insertion of new devices. Although initially targeted for image sensors, the proposition can also be deployed to increase the quality of service of traditional sensors by guaranteeing that important messages can be sent despite the duty-cycle regulation limit. |

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.
