In this paper, we statistically analyze the BER performance of a threshold-based parallel multiple beam selection scheme for a free-space optical (FSO) based system with wavelength division multiplexing (WDM) in cases where a pointing error has occurred under Gamma turbulence conditions, which are a good approximation of Gamma-Gamma distribution. Our derived results based on the Gamma distribution as an approximation of the Gamma-Gamma distribution can be used as approximated performance measure (lower) bounds.

The 3GPP Release-13 has introduced a Narrowband Internet of Things (NB-IOT) which is capable of Low Power Wide Area (LPWA) IoT service. NB-IoT can interfere with LTE cellular because the NB-IoT uses the license band differently from the LPWA IoT (Sig-fox, LoRa, and so on) using the unlicensed band. In this paper, it is shown that NB-IoT can cause interference even though subcarrier frequency 15 kHz like LTE is used, and the degree of interference is shown through testing. The test results show how to suppress NB-IoT interference for LTE and LTE resource allocation.
3GPP Release-13引入了能够实现低功耗广域(LPWA)物联网服务的窄带物联网(NB-IOT)。NB-IoT可能会干扰LTE蜂窝网络,因为NB-IoT使用的许可频带与使用未许可频带的LPWA IoT (Sig-fox、LoRa等)不同。本文证明了NB-IoT在使用LTE一样的15 kHz副载波频率的情况下也会产生干扰,并通过测试显示了干扰的程度。测试结果显示了如何抑制NB-IoT对LTE的干扰和LTE资源分配。

NDN(Named Data Networking, NDN) which is one of the next generation network architectures based on named-data, uses in-network caching. Cache has limited capacity, so the cache replacement policy determines which content is evicted when the cache space is full. This paper analyzes some cache replacement strategies in NDN, and puts forword a cache replacement strategy based on hierarchical popularity, then compares the effect of different cache replacement strategies to the cache performance through simulation experiments. Cache performance is evaluated in provision of cache hit ratio.

LED color detection is a vital part in visual-MIMO system. For deciding transmitted symbols from an LED array image, it is important to detect the color of LED on receiver side. In this paper, we propose a training algorithm, called boosting neural network (BNN) to predict the color of LED on receiver side. First, we take the image of LED array and segment the LED image by using LED detection algorithm. After segmenting the LED image, the LED image is resized in 10 by 10 dimension that means 100 pixels. Each pixel is the input to the BNN model for each RGB color channel. For studying the behavior of each color LED image in low (565 lux) and strong (2450 lux) environmental light intensity, we train our BNN model for low and strong environmental light intensity. Finally, we compare the performance of our BNN model with the regression analysis model at low and strong environmental light intensity. We obtain greater closeness accuracy for each color channel at both environmental light intensities.
LED颜色检测是视觉多输入多输出系统的重要组成部分。为了从LED阵列图像中确定传输符号,检测接收端LED的颜色是很重要的。本文提出了一种增强神经网络(boosting neural network, BNN)的训练算法来预测接收端LED的颜色。首先,我们取LED阵列的图像,利用LED检测算法对LED图像进行分割。在分割LED图像后,LED图像被调整为10 × 10的尺寸,即100像素。每个像素是每个RGB颜色通道的BNN模型的输入。为了研究每个彩色LED图像在低(565 lux)和强(2450 lux)环境光强度下的行为,我们训练了低和强环境光强度的BNN模型。最后,我们比较了BNN模型与回归分析模型在弱光和强光环境下的性能。在两种环境光强度下,我们获得了每个颜色通道更大的接近精度。

With the time-to-market pressures for mobile app development is increasing, its development cycle is getting shorter and developers have little to no time for security remediation. Many mobile app developers overlook the security quality of the software in the development cycle. Mobile app flaws and security defects could open doors for hackers to easily attack mobile apps. Early elimination of possible security vulnerability will help to secure our software, and mitigate the security risk threats from potential malicious attacking. However, many developers lack awareness of the importance of security vulnerability and the necessary secure software development knowledge and skills. An effective security vulnerability detecting tools integrated with IDE would be very beneficial for software developers. In this paper we explore the Android common ICC vulnerability and present ICC intent flaw detectors with open source FindSecurityBugs integrated in Android Studio IDE.

Fair and Efficient Channel Observation-Based Listen-Before Talk (CoLBT) for LAA-WiFi Coexistence in Unlicensed LTE 基于信道观测的公平高效的LAA-WiFi无授权LTE共存先听后讲(CoLBT

License Assisted Access-WiFi (LAA-WiFi) coexistence allows the operations on the unlicensed spectrum for Long Term Evolution (LTE) along with existing unlicensed wireless local area networks (WLANs). The current spectrum access process of legacy WLANs uses clear channel assessment (CCA) and carrier sense multiple access with collision avoidance (CSMA/CA), where the spectrum is sensed before use and a random binary exponential backoff (BEB) mechanism is employed for collision avoidance. While LAA uses a listen-before-talk (LBT) mechanism, moderately similar to the CCA CSMA/CA for channel access. However, there is a fairness issue when these two technologies coexist. In this paper, we propose a channel observation-based LBT (CoLBT) mechanism for fairness in LAA-Wi-Fi coexistence scenarios. Specifically, we introduce a more realistic practical channel observation-based collision probability observed by the LAA evolved Node B (eNB) to adaptively scale-up and scale-down the backoff contention window for channel contention, to reduce the waste of resources and improve LAA-WiFi coexistence performance. Simulation results validate that the proposed CoLBT mechanism is effective in LAA-WiFi coexistence scenario and can improve fairness performance, compared with the current mechanism of LBT.
LAA-WiFi (License Assisted Access-WiFi)共存,允许在LTE (Long Term Evolution)的无授权频谱上与现有的无授权无线局域网(wlan)一起运行。传统无线局域网目前的频谱接入过程采用清晰信道评估(CCA)和载波感知多址避碰(CSMA/CA),其中频谱在使用前被感知,并采用随机二进制指数后退(BEB)机制来避免碰撞。而LAA使用先听后讲(LBT)机制,与CCA的CSMA/CA通道访问适度相似。然而,当这两种技术共存时,存在公平性问题。在本文中,我们提出了一种基于信道观测的LBT (CoLBT)机制来实现LAA-Wi-Fi共存场景下的公平性。具体而言,我们引入了一种更现实的基于实际信道观测的碰撞概率,由LAA进化节点B (eNB)自适应地放大和缩小信道争用的退退争用窗口,以减少资源浪费,提高LAA- wifi共存性能。仿真结果验证了所提出的CoLBT机制在LAA-WiFi共存场景下的有效性,与现有的LBT机制相比,可以提高公平性性能。
