| Abstract | Tactical environments are usually scattered with a number of sensors that collect different types of information. This data can be correlated, combined, and otherwise processed using sensor fusion algorithms to provide warfighters with a more accurate representation of the situation and environment. Sensor fusion algorithms can dramatically increase situational awareness; to accomplish this, they require access to the data collected by multiple sensors on a fusion node. In such an approach, the amount of data collected by the sensors and sent over the network can be very large: some sensors may generate an update every few milliseconds; others may generate large updates such as imagery; a substantial number of sensors may be present in the network. Moving large amounts of data in a tactical environment is a complex task due to the low bandwidth available and the unreliability of the channel typical of the wireless networks in the field. We aim to improve the bandwidth utilization to increase the sensor fusion algorithm performance and propose to achieve this goal using the novel concept of a Process Integrated Mechanism (PIM): instead of sending the information to a centralized node for processing, the PIM framework transparently migrates the fusion algorithm that processes the information to the sensor nodes. Using the PIM middleware, only the current state of the fusion process is sent from one node to the next one, granting the process seamless access to the information as if it were stored locally. Our findings show that in a variety of cases the bandwidth consumption of our approach is lower than the bandwidth needed using other frameworks. |

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.
