An attribute switching mechanism for mobile networks 移动网络的一种属性交换机制
Chen-Hung Yu, Weiping Li
This paper presents a new mechanism for data transmission over mobile networks. The ultimate goal of designing the next generation mobile network is to have a single network that can support all applications with different data attributes. The proposed mechanism in this paper is inspired by the Mechanism Design Theory that is an emerging branch of game theory and has been used successfully in economics. The proposed attribute switching mechanism provides incentives for network applications to label their data attributes honestly and processes the data according to their attributes so that all applications achieve their best possible data transmission results without taking unnecessary network resources. Our simulation results have shown that the proposed approach performs better than other methods.

Anti-forensic deletion scheme for flash storage systems 闪存防取证删除方案
Jaewook Kwak, Hyung Chan Kim, I. Park, Y. Song
Unlike hard disk drive (HDD)-based storage systems, NAND flash memory-based storage systems require an additional layer called the flash translation layer (FTL) between the file system and storage devices. The FTL helps file systems use NAND flash memory in the same way as HDD by using the address mapping function. However, this function can produce a side effect of delaying the physical erasure point of data when deleting data. In this paper, we analyze the time delay phenomenon of data erasure from the flash storage device that uses the FTL and propose the anti-forensic deletion scheme, which can minimize the delay time. The experimental results confirm that the proposed deletion scheme is effective in reducing the delay time of data erasing.
与基于硬盘驱动器(HDD)的存储系统不同,基于NAND闪存的存储系统需要在文件系统和存储设备之间附加一个称为闪存转换层(FTL)的层。FTL通过地址映射功能,帮助文件系统像HDD一样使用NAND闪存。但是,该函数在删除数据时会产生延迟数据物理擦除点的副作用。本文分析了使用FTL的闪存设备在擦除数据时的时间延迟现象,提出了一种能够将延迟时间最小化的反取证删除方案。实验结果表明,所提出的删除方案能够有效地减少数据擦除的延迟时间。

Yuanying Peng, K. Yu
Nowadays Internet user behavior becomes more and more complicated due to application diversity. It is important to analyze user behavior on specific websites such as e-commerce, education, and healthcare in order for personalized recommendation or targeted advertisement. In this paper, based on the large-scale traffic flow data of real network and crawling data from websites, we focus on the analysis of user browsing behavior on automobile websites. First of all, data pre-processing and statistical analysis based on MapReduce framework are designed and implemented, which is mainly to transform the flow data type to sequential dataset. By improving regular expressions matching method in distributed computing, the running time is reduced from O(N) to O(1). Secondly, we apply the sequential pattern mining algorithm AprioriAll to analyze the sequential dataset. The analysis result reflects the preference of the users when browsing automobile websites to acquire their wanted information.

Signal processing on heterogeneous network based on tensor decomposition 基于张量分解的异构网络信号处理
Yuqian Qiao, K. Niu, Zhiqiang He
Recent researches on graph signal processing (GSP) have been successfully applied on homogeneous networks. However, in real-world network, nodes and relationships of multiple types are usually heterogeneous. In this paper, we discuss signal processing on heterogeneous networks. Heterogeneous networks are modeled as hypergraphs by adjacency tensor. An algorithm called signal processing on tensor (TSP) is proposed to analyze signal propagation in vertex and frequency domain. In vertex domain, TSP propagates signals not only on homogeneous subgraphs but also on hypergraphs including hyperlinks of multi-subgraphs. In frequency domain, tensor Fourier transform is defined based on factor matrices of higher-order singular value decomposition (HOSVD), which is used to describe high and low frequencies of signals on hypergraphs. Finally, we verify algorithm by data classification on network generated randomly. Comparing to classification on homogeneous subgraphs merely, our algorithm achieves higher accuracy.
近年来,图信号处理(GSP)的研究已成功地应用于同构网络。然而,在现实网络中,多种类型的节点和关系通常是异构的。本文讨论了异构网络中的信号处理问题。利用邻接张量将异构网络建模为超图。提出了一种信号张量处理(TSP)算法来分析信号在顶点域和频域的传播。在顶点域,TSP不仅在齐次子图上传播信号,而且在包含多子图超链接的超图上传播信号。在频域,基于高阶奇异值分解(HOSVD)的因子矩阵定义了张量傅里叶变换,用于描述超图上信号的高频和低频。最后,在随机生成的网络上对算法进行数据分类验证。与仅在齐次子图上进行分类相比,我们的算法达到了更高的准确率。

Suyou Li, Zhigang Guo, Guochu Shou, Yihong Hu, Hongxing Li
Mobile Edge Computing (MEC) provides mobile and cloud computing capabilities within the access network. Network Functions Virtualization (NFV) leverages standard IT Virtualization technology to decouple the network functions from the underlying physical infrastructure. Basing on the ICT demand, MEC can be consolidated into NFV, as a network element within access network. This paper presents an architecture of NFV-based MEC platform and analyzes its Quality of Service (QoS) compared with the remote servers (Shenzhen and Qingdao). Then, this paper measures the Quality of Experience (QoE) of HTTP videos deployed in the servers. The result shows MEC can offer a service environment with higher bandwidth, which supports 10-fold gains, and ultra-low latency, jitter and packet loss rate. Moreover, along with the higher resolution and bitrates, the range of the video QoE improvement on this platform rises compared with the remote servers. In a word, the NFV-based MEC can achieve better performance than the remote servers.

A low complexity decision feedback equalizer for single-carrier amplify-forward MIMO relay system 用于单载波放大前向MIMO中继系统的低复杂度决策反馈均衡器
Yang Liu, Chao Dong, Zhiqiang He
In this paper, we introduce a block iterative frequency domain decision feedback equalizer with noise prediction (NP-BI) for single-carrier (SC) multiple input multiple output (MIMO) relay systems. Firstly, we derive the minimum mean-squared error (MMSE) equalizer at the destination node. Then the decision feedback equalizer coefficients can be calculated according to the error covariance matrix of the MMSE equalizer and the equivalent channel frequency-domain (FD) response. Then, we combine the spatial precoding matrix with the decision feedback equalizer at the source node, which performs better than the frequency domain equalization with noise prediction (FDE-NP), especially when the number of antennas is large. In addition, NP-BI has a lower computational complexity than FDE-NP.

Iterative channel estimation algorithm based on compressive sensing for GFDM 基于压缩感知的GFDM迭代信道估计算法
Jinnian Zhang, Yan Li, K. Niu
Generalized Frequency Division Multiplexing (GFDM) is a promising solution for the cellular system of the fifth generation (5G) PHY layer because its flexibility can address the different application requirements. However, due to the pulse shaping, there is inherent interference existing in the received signal, which has a negative impact on pilot-based channel estimation. Although the interference on the pilot symbols can be eliminated at the transmitter by using precoding matrices, the accompanied transmitting power penalty increases with the non-orthogonality of subcarriers and subsymbols. In our work, we propose an iterative method for interference cancellation at the receiver, which can efficiently mitigate the effect of neighboring symbols on pilots without transmitting power penalty. In addition, to improve the accuracy of channel estimation, we adopt the compressive sensing (CS) technology. Simulation results show that our proposed channel estimation algorithm is efficient even when the interference is severe, and by using orthogonal match pursuit (OMP) recovery algorithm, the performance of our algorithm can be close to the Cramer-Rao bound (CRB).
通用频分复用技术(GFDM)是第五代(5G)蜂窝系统物理层的一种很有前途的解决方案,因为它的灵活性可以满足不同的应用需求。然而,由于脉冲整形,接收信号中存在固有干扰,这对基于导频的信道估计产生了负面影响。虽然利用预编码矩阵可以消除对导频符号的干扰,但伴随的发射功率惩罚随着子载波和子符号的非正交性而增加。在我们的工作中,我们提出了一种迭代的接收机干扰消除方法,该方法可以有效地减轻相邻符号对导频的影响,而不会造成发射功率损失。此外,为了提高信道估计的精度,我们采用了压缩感知(CS)技术。仿真结果表明,即使在严重干扰情况下,我们提出的信道估计算法也是有效的,并且通过使用正交匹配追踪(OMP)恢复算法,我们的算法性能可以接近Cramer-Rao界(CRB)。

Simulation results show that our proposed channel estimation algorithm is efficient even when the interference is severe, and by using orthogonal match pursuit (OMP) recovery algorithm, the performance of our algorithm can be close to the Cramer-Rao bound (CRB).","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127967071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
