| Description | Author affiliation: Sch. of Mech. & Aerosp. Eng., Seoul Nat. Univ., Seoul, South Korea (Jae Hyun Yoo; Kim, H.J.) In tracking a mobile target using wireless sensor networks (WSN), efficient sleep scheduling is needed to reduce energy consumption without severely deteriorating the tracking performance. Conventional prediction-based sleep scheduling techniques require position, velocity and even acceleration of the target in order to wake up the nodes according to the next predicted location of the target. In these data, effects of sensor faults and uncertainties are included, which can degrade the overall performance. In order to address this issue, we propose a new predictive target detection algorithm which uses only local measurement, eliminating the need for communication among nodes. The proposed prediction algorithm provides a prediction of the number of detections that will occur starting from the moment when a target enters the sensor coverage area until it leaves. This algorithm is evaluated via experiments including several movement scenarios of the target. The results show that the algorithm accurately reflects the remaining number of target detections until the target leaves. In addition, the prediction algorithm is applied to sleep scheduling and compared with the circle-based sleep scheduling. Our scheduling strategy improves energy efficiency with a very small, negligible loss in the tracking performance. |

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.
