摘要：
The future Internet of Things (IoT) will enable Internet connectivity for a vast amount of battery-powered devices, which usually need to communicate with each other or to some remote gateways through multihop communications. Although ZigBee has become a widely used communication technology in IoT, Wi-Fi, on the other hand, has its unique advantages such as high throughput and native IP compatibility, despite its potentially higher energy consumption. With the development of IoT, more and more IoT devices are equipped with multiple radio interfaces, such as both Wi-Fi and ZigBee. Inspired by this, we propose a dual-interface dual-pipeline scheduling (DIPS) scheme, which leverages an activation pipeline mainly constructed by low-power ZigBee interfaces to wake up a data pipeline constructed by high-power Wi-Fi interfaces on demand, toward enabling multihop data delivery in IoT. The objective is to minimize network energy consumption while satisfying certain end-to-end delay requirements. Extensive simulations and prototype-based experiments have been conducted. The results show that the energy consumption of DIPS is 96.5% and 92.8% lower than that of the IEEE 802.11's standard power saving scheme and a state-of-the-art pipeline-based scheme in moderate traffic scenarios, respectively.

摘要：
The future Internet of Things (IoT) will enable Internet connectivity for a vast amount of battery-powered devices, which usually need to wirelessly communicate with each other or to some remote gateways through multi-hop communications. Although ZigBee has become a widely used communication technology in IoT, Wi-Fi, on the other hand, has its unique advantages such as high throughput and native IP compatibility, despite its potentially higher energy consumption. With the development of IoT, more and more IoT devices are equipped with multiple radio interfaces, such as both Wi-Fi and ZigBee. Inspired by this, we propose a cross-interface power saving management (CPSM) scheme, which leverages the existing low-power ZigBee interfaces to wake up the high-power Wi-Fi interfaces on demand towards enabling multi-hop communications in IoT. The objective is to minimize the network energy consumption while satisfying certain end-to-end delay requirements. The results of extensive simulations and prototype-based experiments have demonstrated that the energy consumption of our proposed CPSM is 79.2% and 68.9% lower than those of the IEEE 802.11’s standard power saving scheme and a state-of-the-art scheme in moderate traffic scenarios, respectively. © 2017 Elsevier B.V.

摘要：
Predicting traffic flow is one of the fundamental needs to comfortable travel, but this task is challenging in vehicular cyber–physical systems because of ever-increasing uncertain traffic big data. Although deep-learning (DL) methods with outstanding performance recently have become popular, most existing DL models for traffic flow prediction are fully deterministic and shed no light on data uncertainty. In this study, a novel fuzzy deep-learning approach called FDCN is proposed for predicting citywide traffic flow. This approach is built on the fuzzy theory and the deep residual network model. Our key idea is to introduce the fuzzy representation into the DL model to lessen the impact of data uncertainty. A model of fuzzy deep convolutional network is established to improve traffic flow prediction while investigating the spatial and temporal correlation of traffic flow. We further propose pre-training and fine-tuning strategies that efficiently learn parameters of the FDCN. To the best of our knowledge, this is the first time that a fuzzy DL approach has been applied to represent traffic features for traffic flow prediction. Experimental results demonstrate that the proposed approach to traffic flow prediction has superior performance compared with state-of-the-art approaches. © 2018 Elsevier B.V.

摘要：
Sensing image has important geographical structure for detection and identification of the sense. In military and civilian, they have very important significances. It is proposed by support vector machine (SVM) and local binary pattern model in high-resolution remote sensing image of detection algorithm. Firstly, according to the target resolution remote sensing image features, sample image's texture features and structure features have the reference points of information diffusion eigenvectors and sample-based training support vector machine classifiers to achieve goals coarse split. Then coarse segmentation results are the basis of the local binary pattern (LBP) model extraction precise contours. With one meter resolution satellite images experiment testing, the results are shown that the proposed algorithm has high accuracy and flexibility. It can be accurately detected by complex background target area with broad applicability. ©2013 by CESER Publications.

摘要：
With the different colourful gradient operators, the binding algorithm has been applied to image segmentation. In order to make the color image of the edge detection operator in line with the resolution of the human eye on the image information and prevent the problem of the over-detection of the edge of the insensitive area, the paper has proposed the combination algorithm using the adaptive color image and value estimation method of color threshold. The construction has comprised with the partial chromatic aberration of the brightness mask and the contrast sensitivity threshold. The paper has proposed visual impact of the weight factor to solve some problems of image segmentation. It is combined with the brightness and colors' information. The color of partial background is the spatial frequency of human vision. The experiment results have shown that the proposed algorithm can accurately detect the image edge and effectively resist noise image interference. ©2013 by CESER Publications.

摘要：
The distributed architecture of a multi-camera surveillance system is given, a data fusion scheme using path model and estimated target shape changes is described, and a collaborative algorithm in distributed multi-camera surveillance system is proposed in order to track people reliably. Based on the results of multi-camera data fusion, the proposed algorithm allocates cameras to objects according to task priorities, the distance between camera and target and the visibility of targets, which is characterized by the system assigning cameras to the visible target with high priority and the nearest distance to the camera. It is called Priority and Distance Algorithm (PDA). The Quality of Service (QoS) function is introduced to describe the system performance. Experiment results show that the proposed method can coordinate cameras to track people reliably and has good robustness. ©2011 Praise Worthy Prize S.r.l. - All rights reserved.
