Abstract | The energy consumption of sensor nodes, network induced delay and packet dropouts due to congestion are the major concerns in some real time sensor network applications where measurements are reported regularly or periodically to perform control and actuation under a certain time constraint. Here, we address these issues in our TDMA scheduling (Hybrid) approach designed for cluster based large scale Wireless Sensor and Actuator network (WSAN). The proposed hybrid scheme inherently employs simple Breadth-first and Depth-first node visiting techniques over the routes to decide time slots of the nodes with spatial reuse possibilities in deterministic time. The approach suits well for the networks when the entire schedule is recomputed periodically due to maintenance or change in routing to balance the nodes energy. The scheme is analyzed in terms of savings in energy consumption, number of time slots, % slots reuse, throughput and packet dropout due to buffer congestion. Simulation results confirm that the approach is more desirable for the resource limited WSAN networks designed for industrial applications. |

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.
