Security is an important concern in wireless networks. In this paper, we study secure transmission in heterogeneous massive MIMO systems. Base station (BS) with large-scale antenna transmits signal to mobile terminals through low power nodes (LPNs) in the presence of passive multi-antenna eavesdroppers. We consider the secure downlink transmission based on cooperative jamming relay. Meanwhile we employ artificial noise to enhance the security. Our simulation results reveal in heterogeneous massive MIMO systems with Jammer and AN, the SNR of MT is higher than Eve, the obtained positive secrecy capacity prove this scheme can guarantee the secure transmission.

To manage Ethernet networks efficiently, detailed and accurate knowledge of their topology is needed, like network partition, performance prediction are based on network topology. In this paper, we proposed an algorithm to discover physical layout topology structure of Ethernet networks with incomplete address forwarding table information. This algorithm can handle both layer-2 switches with VLAN and layer-3 switches. We have implemented our algorithm in networks of some universities, and it works well in these networks divided by VLAN.

Software Defined Networking (SDN) is considered to meet the future needs of the 5G mobile networks. However, there have been only a few works so far that address the security issues in SDMN (Software Defined Mobile Networks), and all the proposed approaches have their drawbacks. So, in this context, a new security paradigm based on SDN introduces many opportunities and provides the potential to solve the security problem in the mobile core network. In this paper, we present the SDS-SC, a software defined security architecture for SDN based 5G network. With centralized security controller that communicates with SDN network controller, flexible and network-aware security services could be provided for mobile users on-demand. We also highlight how security applications could be developed easily in our architecture through application interface on top of the security controller.

User reviews, in the form of short unstructured natural texts, often provide rich information to benefit product adoption or service improvement. Aspect can be extracted as the abstract meaning from the reviews. Traditional methods have employed either rule-based templates or bag-of-words features for aspect extraction from text. However, these models cannot effectively handle short texts, especially in Chinese reviews. In this paper, we address the issue by learning the character embeddings as the basic semantic unit and incorporating the compositional sentence-level representation into a neural network approach for review aspect classification. For that, the character embeddings from the reviews are learned in position-based and clustered-based fashions, and then combined into sentence vectors to yield better text representations. Extensive experiments on real world data set suggest that our proposed model highly outperforms the state-of-the-art methods for review aspect extraction task.

Frequency Hopping Communication Signal (FHCS) is widely used in military filed especially in military communication for its good anti-jamming performance and multiple access capability. Due to the rapid development of communication technology, the band width of FHCS become wider and wider, frequency become larger and larger. There will be a huge pressure on Analog to Digital Converter (ADC) as well as DSP device. Theory of compressed sensing (CS) enables a successful reconstruction of sparse signal by sampling at a sub-Nyquist sample rate. Analog to Information Converter is a better implementation of CS, which includes Random Demodulator scheme (RD) and Modulated Wideband Converter (MWC). In this paper, we apply these two schemes into FHCS's compressed sampling and reconstruction. Simulations are performed to verify that RD scheme can reconstruct signal successfully with high possibility with relatively low time complexity at low sample rate. Besides, MWC guarantees the accuracy and efficiency of signal collection.

With the development of information technology, people's demand for wireless video is improved. Recently, an uncoded video transmission scheme called SoftCast was proposed for wireless video communication which provided graceful transition quality. However, when channel bandwidth is low, we need to discard some packets before transmitting to meet the requirement of bandwidth. This will cause a sharp decline on receiver video quality. This paper proposed an unequal block method (UBCAST) based on the frequency of image. UBCAST divides the lowest frequency into the biggest block to protect low frequency information, and divides the highest frequency into the smallest block which can protect low frequency packets from being discarded. What's more we can increase high frequency block proportion to improve transmission quality. And we can also increase low frequency block proportion to increase discarding packets proportion to meet the bandwidth requirement of channel. The experimental results show that when transmitting video information completely, we can improve the performance of the original SoftCast using 8∗8 block up to 2dB. When the SNR of channel is 20dB, discarding packets, we can even get a 10dB gain.

An important and widespread topic in cloud computing is text analyzing. People often use topic model which is a popular and effective technology to deal with related tasks. Among all the topic models, sLDA is acknowledged as a popular supervised topic model, which adds a response variable or category label with each document, so that the model can uncover the latent structure of a text dataset as well as retains the predictive power for supervised tasks. However, sLDA needs to process all the documents at each iteration in the training period. When the size of dataset increases to the volume that one node cannot deal with, sLDA will no longer be competitive. In this paper we propose a novel model named Mr.sLDA which extends sLDA with stochastic variational inference (SVI) and MapReduce. SVI can reduce the computational burden of sLDA and MapReduce extends the algorithm with parallelization. Mr.sLDA makes the training become more efficient and the training method can be easily implemented in a large computer cluster or cloud computing. Empirical results show that our approach has an efficient training process, and similar accuracy with sLDA.

In this paper, we present the experimental study based on filtering techniques to extract essential vital signals such respiration rate (RR) using continuous wave (CW) Doppler radar sensor. Due to the fact that the CW Doppler radar offers very high sensitivity towards minor movements, based on this technology, various filtering techniques were introduced and the detection rate was compared to the reference devices to conclude the leading method for the respiration rate detection.
