The k-Nearest Centroid Neighbor rule is one of the effective algorithms in pattern classification. In this paper, with the goal of overcoming the sensitivity issue on the choice of the neighborhood size k and improving the classification performance, two new distance-weighted k-nearest centroid neighbor rules are proposed. According to the geometric distribution and the similarity between the nearest centroid neighbors and the query pattern, the proposed rules mainly employ the new weighted voting function to give weights in the classification voting. In order to verify the classification behavior of the proposed classifiers, we conduct extensive experiments on twelve real data sets, in comparison with the other KNN-based classifiers. Experimental results show that the new classifiers are effective algorithms for the classification tasks, owing to their satisfactory classification performance and robustness over a wide range of k. © 2017.

As the global internet of things increasingly is popular with consumers and business environment, network flow management has become an important topic to optimize the performance on internet of things. The rigid existing internet of things (IoT) architecture blocks current traffic management technology to provide a real differentiated service for large-scale IoT. Software-defined internet of things (SD-IoT) is a new computing paradigm that separates control plane and data plane, and enables centralized logic control. In this paper, we first present a general framework for SD-IoT, which consists of two main components: SD-IoT controllers and SD-IoT switches. The controllers of SD-IoT uses resource pooling technology, and the pool is responsible for the centralized control of the entire network. The switches of SD-IoT integrate with the gateway functions, which is responsible for data access and forwarding. The SD-IoT controller pool is designed as a vertical control architecture, which includes the main control layer and the base control layer. The controller (main controller) of the main control layer interacts upward with the application layer, interacts with the base control layer downwards, and the controller (base controller) of the basic control layer interacts with the data forwarding layer. We propose a dynamic balancing algorithm of the main controller based on election mechanism and a dynamic load balancing algorithm of the basic controller based on the balanced delay, respectively. The experimental results show that the dynamic balancing algorithm based on the election mechanism can ensure the consistency of the messages between the main controllers, and the dynamic load balancing algorithm based on the balanced delay can balance between these different workloads in the basic controllers.

Shape Retrieval Using ECPDH with Dynamic Programming

Journal of computer and Communications 2016年第16期4卷 63-78页

作者： Xin Shu Lei Pan Yunsong Qi School of Computer Science and Engineering Jiangsu University of Science and Technology Zhenjiang China School of Internet of Things Jiangnan University Wuxi China

The matching and retrieval of the 2D shapes are challenging issues in object recognition and computer vision. In this paper, we propose a new object contour descriptor termed ECPDH (Elliptic Contour Points Distribution Histogram), which is based on the distribution of the points on an object contour under the polar coordinates. ECPDH has the essential merits of invariance to scale and translation. Dynamic Programming (DP) algorithm is used to measure the distance between the ECPDHs. The effectiveness of the proposed method is demonstrated using some standard tests on MPEG-7 shape database. The results show the precision and recall of our method over other recent methods in the literature.

Orthogonal resource sharing scheme for device-to-device communication overlaying cellular networks: a cooperative relay based approach

science China(Information sciences) 2015年第10期58卷 70-78页

作者： ZHANG GuoPeng LIU Peng YANG Kun DU Yao HU YanJun Internet of Things Research Center China University of Mining and Technology School of Computer Science and Electronic Engineering University of Essex School of Information and Electrical Engineering China University of Mining and Technology

In this paper, we propose a device-to-device(D2D) communication scheme to improve local services in cellular networks. By employing cooperative relay(CR) technology, D2 D and cellular communications can operate in orthogonal resource sharing(ORS) mode with the aim of optimizing the data rates for local D2 D users while fulfilling the minimum rate requirements for prioritized cellular users. In the proposed CR-based ORS scheme, we consider a cellular communication that is willing to share part of the occupied bandwidth resource with some D2 D communications. Hence, the newly-obtained resource can be used by a D2 D communication for the following two purposes, i.e., to compensate the rate loss of the cellular communication through cooperative relaying and to communicate its own information so as to increase its own rate. We formulated this CR-based ORS problem as a non-convex optimization problem. Hence, a global maximizer may not exist for the *** find the optimal solution for the problem, an effective heuristic algorithm is developed. Simulation results show that the proposed D2 D communication scheme can significantly increase the rates of local D2 D users and also fulfill the minimum rate requirements of cellular users.

Using full duplex relaying in device-to-device(D2D)based wireless multicast services:a two-user case

D2D communication has been proposed as an important supplement to the existing centralized cellular networks which allows two physically adjacent cellular user equipments(UEs) to communicate *** paper concerns using D2 D to improve wireless multicast services in cellular networks. Specially, we consider a D2 D transmitter UE can act as a full-duplex(FD) relay to assist a cellular multicast from a base station(BS) to a group of two UEs. And a new scheme which allows an intra-cell D2 D retransmission to underlay a cellular multicast is proposed. Under the constraint of the minimum signal-to-interference-and-noise ratio(SINR) required by each of the receiver UEs, the aim of the scheme is to select the best UE in a multicast group to perform the D2 D retransmission with the serving BS. Thus, the aggregate transmit power consumed at the BS and at the selected UE can be minimized. The numerical results show that the proposed scheme outperforms traditional cellular multicast scheme as it consumes less transmit power to achieve the same SINR target at the receiver UEs.

With increase demand on wireless services, equipment supporting multimedia applications has been becoming more and more popular in recent years. With billions of devices involved in mobile internet, data volume is undergoing an extremely rapid growth. Therefore, data processing and network overload have become two urgent problems. To address these problems, extensive study has been published on image analysis using deep learning, but only a few works have exploited this approach for video analysis. In this paper, a hybrid-stream big data analytics model is proposed to perform big data video analysis. This model contains four procedures, i.e., data preprocessing, data classification, data recognition and data load reduction. Specifically, an innovative multi-dimensional Convolution Neural Network (CNN) is proposed to obtain the importance of each video frame. Thus, those unimportant frames can be dropped by a reliable decision-making algorithm. Then, a reliable key frame extraction mechanism will recognize the importance of each frame or clip and then decide whether to abandon it automatically by a series of correlation operations. Simulation results illustrate that the size of the processed video has been effectively reduced. The simulation also shows that proposed model performs steadily and is robust enough to keep up with the big data crush in multimedia era.

Radio Frequency Identification technology (RFID) is the key technology to realize the internet of things. Currently, using RFID to locate objects indoor is a hot topic in the research on the application of RFID. In this paper, we propose an RFID system based on RFID technology and Wi-Fi wireless communication technology. And we design a corresponding handheld device client software to realize a visual book search and management system. This system can not only greatly improve the efficiency of book search and management but also save the manpower and material resources to a large extent, which has a practical application value.
