Optimal allocation of multi-sensor passive localization

Passive Source Localization of Sensor Arrays

Multi-target multi-sensor localization and tracking using passive antennas and optical sensors on UAVs

In this work we focus on the task to localize and track multiple non-cooperative targets by a passive antenna array and an optical sensor. Both sensor systems are mounted on a UAV and obtain bearing measurements from the targets, where the number of targets is unknown. To solve the localization and tracking problem, the imprecise but unique bearing data collected from the antenna array has to b...

Ultrasonic Sensor Network: Target Localization with Passive Self-Localization

A flying robot is localized using ultrasonic sensor network distributed on the ground. This requires localization of sensor nodes first. In absence of RF link between target and sensors, weighted Multi-Dimensional Scaling (MDS) with Gradient Descent is used to localize the sensors from outlier free data obtained from generating a locally linear manifold. After initialization, an Extended Kalman...

A multi-hop PSO based localization algorithm for wireless sensor networks

A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...

System Architectures for Multi-Sensor Task Allocation

Heterogeneous sensor networks are increasingly being deployed to support users on the field who require many different kinds of sensing tasks, such as detecting people who may need help or monitoring collapsing buildings. Sensors may be scarce and in high demand. Sensing tasks might compete for the exclusive usage of available sensors. Such an environment is highly dynamic with, for example, se...
