Fault-tolerance is an important function in target tracking application using wireless sensor networks. We propose in this paper, an efficient fault-tolerant approach for target tracking that prevents the loss of the target. Instead of using a single prediction mechanism, our approach uses a multi-level incremental prediction technique that adjusts the prediction precision of the target movement....
Object tracking is an important application in wireless sensor network (WSN). High-accuracy and energy-efficiency are key requirements. In this paper, we propose a novel face-based object tracking protocol (FOTP), which is used to track the object with low energy consumption and high quality. FOTP combines a hexagon algorithm with face-architecture system model, which can provide precise detection...
Existing target tracking algorithms require the tracker to have access to information-rich sensors, and may have difficulty recovering when the target is out of the tracker's sensing range. In this paper, we present a target tracking algorithm that combines an extremely simple mobile robot with a networked collection of wireless sensor nodes, each of which is equipped with an unreliable, limited-range,...
Due to the advancements in low cost embedded processors and wireless transmission technologies, wireless sensor networks have been commonly used in many civil and military applications. In this study, we propose a cluster based target tracking algorithm for targets moving rapidly in wireless sensor networks. In the existing studies found in the literature, the current leader node at time t predicts...
We investigate the data storage and query problem for object tracking applications in wireless sensor networks. We focus on how to query the object tracking and obtain the object position effectively. The main idea is to apply multiple access entries of a storage link which stores the detected events in local storage and maintain the relation of the sensed data. When an object moves across the sensing...
