Abstract | In this paper, we address one of the wireless sensor network (WSN) management problems - optimization on the execution of multiple commands. The objective of the paper is to provide efficient support for pre-processing a set of commands before disseminating into the sensor network. It is important that only necessary work will be assigned to the sensor network by virtue of strict energy constraint. The problem is NP-hard. We divide the problem into a series of tractable sub-problems along with their solutions. We present a novel hierarchical quadrant-based field partition mechanism to virtually divide the sensor field. We also classify and model WSN management commands. We then identify merging possibilities for a given command, which results in several merging rules and constraints. Lastly, we evaluate a simulated annealing based search algorithm for finding optimal merge order. The results show that energy can be significantly saved within short time-delay while the overall effects of the final command set still satisfies the users' requirements. |

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.
