| Abstract | As compared with 2D wireless camera sensor networks (WCSNs), 3D WCSNs can capture more accurate and comprehensive information for supervisory and military applications. However, 3D WCSNs impose many new challenges for energy-efficiency and interference-mitigation subject to the required coverage rate constraint due to their extensive power consumption for data transmissions and inter-sensor interference over time-varying wireless channels in the 3D WCSNs. To overcome the above-mentioned problems, in this paper we propose the multi-hop cooperative multi-input-multi-output and orthogonal frequency-division multiplexing (MIMO-OFDM) based energy-efficient and interference-mitigating scheme for the 3D clustered WCSNs with the minimum target-object coverage rate constraint. We propose to integrate the cooperative MIMO-OFDM with the new low energy adaptive clustering hierarchy (NEW LEACH) algorithm to increase the spatial diversity of wireless channels, reducing the transmitted power with the constraints of bandwidth and energy in multi-hop WCSNs. In particular, applying the NEW LEACH architecture and using the Nakagami-m model, we develop the cooperative MIMO-OFDM based scheme to implement the energy-efficient and interference-mitigating wireless communications over our multi-hop 3D clustered WCSNs. Then, we model and analyze the performance of our proposed cooperative MIMO-OFDM scheme. Also conducted is a set of simulations which show that our proposed scheme outperform the other existing schemes in terms of energy efficiency and interference mitigation over multi-hop 3D WCSNs. |

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.
