The integration of a plurality of homogeneous or heterogeneous sensors will result in more accurate target detection, node localization, and target tracking than that of a single sensor, and thus WSN plays an important role in military, environment, medical, and industrial fields....
Target tracking in wireless sensor networks (WSN) has brought up new practical problems. The limited energy supply and bandwidth of WSN have put stringent ... T Jing,H Snoussi,C Richard - IEEE/SP Workshop on Statistical Signal Processing 被引量: 114发表: 2007年 Distributed Variational Filtering...
Node localization is one of key technologies in wireless sensor networks (WSN). In practice, the occlusion of obstacles often leads to large non-line-of-sight (NLOS) error. Therefore, the misidentification of LOS (line-of-sight)/NLOS con... H Chu,S Lian,H Yang,... - 《Journal of Phy...
So the basic evaluations of target tracking along with the energy conservation and task allocation optimization techniques for multi sensor and multi target tracking have also been discussed. KeywordsWSN; task allocation; multi sensor; target tracking; energy 展开 ...
Energy-Efficient Communication Methods in Wireless Sensor Networks: A Critical Review A Wireless sensor network (WSN) has important applications such as remote ecological monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller...
sink received the data in order to eliminate the abnormal information and prevent interference of the error data.The simulation results show that the positioning accuracy and tracking trajectory are improved in undesirable condition when using the information detection mechanism compared with the general ...
Recent years have witnessed the deployments of wireless sensor networks in a class of mission-critical applications such as object detection and tracking. These applications often impose stringent Quality-of-Service requirements including high detection probability, low false alarm rate, and bounded detecti...
Due to limited network resources for sensing, communication and computation, information quality (IQ) in a wireless sensor network (WSN) depends on the algorithms and protocols for managing such resources. In this paper, for target tracking application in WSNs consisting of active sensors (such as...
During the tracking process, the system calculates the future position that the target will move to and activates a set of sensors in advance. When the target leaves its original position, the former sensor set can go back to sleep. In this way, the system can continuously track the target...
Efficient disjoint boundary detection algorithm for surveillance capable WSNs Wireless Sensor Networks(WSN) have given a new approach for applications such as surveillance, tracking, and monitoring. In such monitoring systems, the se... S Shukla,R Misra,A Prasad - 《Journal of Parallel & Distributed...
