| Abstract | Target localization is a motivating application for wireless sensor networks (WSN). Compared to a centralized system for acoustic source localization, a distributed system has many advantages in terms of power consumption, response time and accuracy. This paper proposes a distributed acoustic passive localization method, which can provide adequate precision localization estimation with low computational complexity. The first step of the two-stage algorithm is to measure the azimuth angle based on the time delay of arrival (TDOA) computed by each participating WSN nodes in clusters. That can obtain high precision angle estimation but low precision range estimation. And in the second step the location of acoustic source is calculated from the angles measured above and geometry position of the two clusters. Then the accuracy of localization estimation is discussed in theory, and analyze the influence factors and localization error by simulation. The simulation results validate the performance of the proposed algorithm, and show the precision of localization estimation with dual clusters is superior to one cluster. |

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.
