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.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"1 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":"122371661","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}

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.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"20 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":"127997233","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}

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.

In F-RAN, RRH receives the signal from mobile devices and decides part of tasks to be processed in fog part for computing offloading. With the purpose of offloading sampling signal in fronthaul and separating tasks from cloud part to be processed in fog part, we formulate the problem as a congestion game. And we propose a discrete distribution computing offloading algorithm (DDCO) for F-RAN to solve this game. The DDCO algorithm decides the latency-sensitive mobile to be computed in the fog part such that the fronthaul can be offloaded and Quality of Service (QoS) can be improved. The DDCO algorithm can also balance load in fronthaul in order to improve performance. With the DDCO algorithm, the network get larger throughput and reduce the burden in fronthaul when it achieve a Nash Equilibrium. Finally, we analyze the feasibility of the algorithm. Numerical result corroborate that the DDCO algorithm can well improve throughput compared with the traditional C-RAN network.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"1 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":"129211478","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}

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.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"100 2 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":"131479303","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}

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.

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).","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}
