| Abstract | How to estimate the collaborative detection probability (CDP) for given certain number of sensors, characteristics of sensor and target is an important problem for coverage in large-scale WSN. A triangular analytical model (TAM) is developed to analyze CDP for a randomly deployment sensors in a 2-dimensional region. Making use of binomially stochastic distribution and normalization analysis methods, we theoretically characterize the relationship between the CDP for 3 collaborative sensors with the factors of sensor normalization node density (NND) and normalization specified path length (NSPL) on an assumption of target moving direction in parallel to X-axis, and work out a lower bounds on the CDP for 3 collaborative sensors at worst case on condition of NSPL no more than 1. The simulations of random deployment of sensors and target randomly moving direction show that the mobile target moving direction assumed in theoretical analysis has little influence on the detection performance analysis, and that the CDP for 3 collaborative sensors can be evaluated by the NND and the NSPL. |

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.
