| Abstract | Wireless sensor networks are emerging as a practical and powerful solution to monitoring problems. However, their use in real world scenarios faces several issues. In fact, sensor nodes are tiny devices with very limited resources, and thus it is important to optimize the battery consumption. For instance, aggregation operations are widely used to minimize transmission operations, that are the most power-consuming operations for the devices. In addition, since sensor nodes operate in open and often hostile environments, security issues must be taken into account. In this paper, we propose a novel aggregation scheme which provides data integrity and privacy-protection and guarantees efficiency with respect to data transmissions, congestion, and memory overhead. To test performance of the scheme, we implemented it within a simulation software environment. We tested its performance to verify its feasibility and we evaluated the computation and power required to ensure security. Simulation results confirmed that our scheme is to be considered efficient enough to being used in real world scenarios. |

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.
