3D range sensors are currently being used in various fields. Creating 3D range sensors requires various techniques, such as object detection, tracking, classification, 3D SLAM, etc. For the pre-processing step, superpixels can improve the performance of these techniques. This paper proposes a novel over-segmentation algorithm, known as superpixels, for 3D outdoor urban range data. Superpixels are...
In this paper, the multiple block localization method for multiple robots in a wide space using iGS system is proposed. The iGS system is developed for the indoor global localization using ultrasonic and RF sensors. This method provides the high accuracy solution using only low price sensors. To measure the distance between a mobile robot and a beacon, the tag on the mobile robot triggers one of the...
In this paper, we develop an adaptive transmission scheme in a wireless sensor network (WSN). Distributed sensors can cooperate with the neighborhood and transmit their data to the data collector by choosing a proper transmission mode adaptively based on the channel conditions and spatial correlation among the sensors. By investigating the statistical properties of a correlated virtual multiple-input...
This paper proposes an asynchronous MAC protocol named Fine-grained wakeup request MAC (FG-MAC) emphasizing a low power listening technique for wireless sensor networks. FG-MAC reduces energy consumption with two methods: fine-grained wakeup-request frame transmission with long acknowledgement, and collision avoidance with the random length preamble. The proposed methods are evaluated by analysis...
