Cloud computing has some major limitations that hinder its application to some specific scenarios (e.g., Industrial IoT and remote surgery) where there are particularly stringent requirements, such as extremely low latency. Fog computing is a specialization of the Cloud that promises to overcome the aforementioned limitations by bringing the Cloud closer to end-users. Despite its potential benefits, Fog Computing is still a developing paradigm which demands further research, especially on security and privacy aspects. This is precisely the focus of this paper: to make evident the urgent need for security mechanisms in Fog computing, as well as to present a research strategy that is being undertaken within the SMOG project, in order to enable a trustworthy and resilient Fog ecosystem.

Social awareness and social ties are becoming increasingly popular with emerging mobile and handheld devices. Social trust degree describing the strength of the social ties has drawn lots of research interests in many fields in wireless communications, such as resource sharing, cooperative communication and so on. In this paper, we propose a hybrid cooperative beamforming and jamming scheme to secure communication based on the social trust degree under a stochastic geometry framework. The friendly nodes are categorized into relays and jammers according to their locations and social trust degrees with the source node. We aim to analyze the involved connection outage probability (COP) and secrecy outage probability (SOP) of the performance in the networks. To achieve this target, we propose a double Gamma ratio (DGR) approach through Gamma approximation. Based on this, the COP and SOP are tractably obtained in closed-form. We further consider the SOP in the presence of Poisson Point Process (PPP) distributed eavesdroppers and derive an upper bound. The simulation results verify our theoretical findings, and validate that the social trust degree has dramatic influences on the security performance in the networks. Copyright © 2018, The Authors.

In this paper we study the survivability feature of airline networks. To measure survivability, we comprehensively consider the network structure measures such as degree distribution, average path length, clustering coefficient, and density;the centrality metrics such as degree centrality and betweenness centrality;as well as the connectivity measures such as maximum connected subgraph size and overall efficiency. Taking three listed China airline companies as examples, namely Air China, China Southern Airlines, and China Eastern Airlines, we provide mass number of simulations to test the survivability of the three companies under random attacks and malicious attacks. The results depict the scalefree features of such networks without small-world characteristics, while the attack simulations reflect the survivability of airline networks clearly. To the best of our knowledge, we are the first to provide case studies for airline networks of individual airline companies in China, which has both theoretical and practical significance in related areas. © 2017 ACM.

network policies are rules and regulations, limitations and settings that allow user to get services from service providers, and policies are the part of SLA document. The main problem of SLA termination between user and service provider is fix policies of network. We propose autonomic policy change mechanism in runtime on the basis of quality of experience, which provide services to client according to SLA, when network usage is on peak. This automatic policy change mechanism in runtime will fulfils user requirements, provides satisfaction to users from network and who remains permanent customers of service provider organization.

arXiv 2018年

作者： Ge, Yinghao Zhang, Weile Gao, Feifei Li, Geoffrey Ye MOE Key Lab for Intelligent Networks and Network Security School of Electronic and Information Engineering Xi'an Jiaotong University Xi'an Shaanxi710049 China State Key Laboratory of Intelligent Technology and Systems Tsinghua National Laboratory for Information Science and Technology Department of Automation Tsinghua University Beijing100084 China Department of Electrical and Computer Engineering Georgia Institute of Technology AtlantaGA30332 United States

In this paper, we develop a novel angle-domain adaptive filtering (ADAF)-based frequency synchronization method for the uplink of a massive multiple-input multiple-output (MIMO) multiuser network, which is applicable for users with either separate or overlapped angle-of-arrival (AoA) regions. For each user, we first introduce the angle-constraining matrix (ACM), which consists of a set of selected match-filter (MF) beamformers pointing to the AoAs of the interested user. Then, the adaptive beamformer can be acquired by appropriately designing the ADAF vectors. Such beamformer can achieve two-stage adaptive multiuser interference (MUI) suppression, i.e., inherently suppressing the MUI from non-overlapping users by ACM in the first stage and substantially mitigating the MUI from adjacent overlapping users by ADAF vector in the second stage. For both separate and mutually overlapping users, the carrier frequency offset (CFO) estimation and subsequent data detection can be performed independently for each user, which significantly reduces computational complexity. Moreover, ADAF is rather robust to imperfect AoA knowledge and side cluster of scatterers, making itself promising for multiuser uplink transmission. We also analyze the performance of CFO estimation and obtain an approximated closed-form expression of mean-squared error (MSE). The effectiveness of the proposed method and its superiority over the existing methods are demonstrated by numerical results. Copyright © 2018, The Authors. All rights reserved.

Increasing the number of public hotspots using Wi-Fi technology is one of opportunity to gain advantage for proposing many new technologies. One of emerging technology is an estimation system to locate the object/person position using Wi-Fi. The object estimation position is the technology to estimate object position accuracy, using signal Received Signal Strength (RSS) from Wi-Fi Access Point. The RSS is an information about the strength of the signal indicates the distance between the access point device. Through the Indoor Positioning System (IPS), RSS value information from multiple access points are processed in order to provide position information. In this study, the IPS using Fuzzy K-Nearest Neighbour (FK-NN) classification method which is a combination of Fuzzy algorithm and K-NN to increase the accuracy of the object estimation position based on the learning data as reference point. Through hybridization from the algorithm is expected to calculate the position estimation more effectively and accurately and minimize errors in estimation. The results show that the algorithm FK-NN obtain the average location error of 2.4 meters with an accuracy percentage of 76%.

IOP Conference Series: Earth and Environmental Science 2019年第1期248卷

作者： R F Malik R Gustifa A Farissi D Stiawan H Ubaya M R Ahmad A S Khirbeet Communication Network and Information Security Research Lab Faculty of Computer Science Universitas Sriwijaya Jalan Srijaya Negara Bukit Besar Bukit Lama Ilir Bar.

Highly dynamic indoor environments being one of the challenge in the Indoor Positioning System (IPS). Collecting the Received Signal Strength (RSS) value from every WiFi access point known fingerprint method is presented by previous researchers. They proposed with different techniques in fingerprint methods to compete similar existing technology such as GPS in term of accuracy. The drawback using fingerprint is the IPS cannot maintain the high performance constantly. In this research, we propose the Deep Neural network (DNN) algorithm for improving the fingerprint method in the IPS. Basically, the fingerprint method consists of two phases, Online and Offline phases. In the off-line, RSS values will be collected from several coordinates as known reference points and stored in the database. The online phase has different step which the current position will be compared to RSS values stored in the database. The DNN method was used to calculate the closest position estimation probability. The IPS using DNN was successfully applied using 5 layers consisting of a 1 input layer, 3 hidden layers and 1 output layer. The input and hidden layer have 28 nodes for each layers and output layer has 2 nodes. The simulation results from RSS data set has achieved 2 meters accuracy. It concluded that DNN performance depends on the number of hidden layers and the number of nodes in each hidden layer.

In cloud computing, a data owner outsources a huge dataset to cloud servers, and authorizes many clients to retrieve data of interest anytime and anywhere. Data outsourcing is helpful to lessen the burden on local data storage and also to improve quality of services. However, the cloud service provider (CSP) outside the data owner's trusted domain may return wrong query results to the client deliberately or ***, query authentication and query correction are of crucial importance to achieve reliable cloud services. In this paper,we consider a flow-oriented cloud environment, where query results will be transmitted in the form of data flow to the clients via networks. Specifically, we propose a two-phase query (TPQ) protocol to support efficient authentication and correction of multi-dimensional range queries. By ingeniously integrating signature chain with Reed Solomon codes, our proposed protocol allows a client to efficiently verify the correctness of query results while performing error correction in an adaptive way. Extensive experiments on a real dataset demonstrate effectiveness of our proposed protocol.
