Ahstract-U-Bus Air is a wireless communication standard for metering systems, targeting gas supplies with a multi-hop network function. As a multi-hop wireless network, U-Bus Air gathers meter reading information connected to a monitoring center. The terminal with the function of connecting to a monitoring center is called a gateway (GW). The multi-hop function is used to connect GWs; this reduces the cost of connecting wide-area wireless networks. However, the order of installing a new terminal is random because it is determined by timing of replacement on meter in individual homes on meters in individual homes. As a result, the installing location of GWs cannot be specified in advance. Consequently, any created network topology will exhibit redundancies, such as unnecessary GWs, or generate many small networks. In this paper, we propose two different redundancy reducing methods that use information of terminals on cloud to reconstruct a network topology. The proposed methods consists of three steps: gathering information, emulating the topology to reduce redundancy using cloud, and providing feedback to rebuild information of each smart meter. We perform a computer simulation to evaluate the packet delivery ratio (PDR) and the reduction ratio of the number of GWs. We confirm that the redundancy can be reduced by using the proposed methods without affecting the performance of the network topology.
u - bus Air是一种用于计量系统的无线通信标准,针对具有多跳网络功能的气体供应。作为一个多跳无线网络,U-Bus Air收集连接到监控中心的抄表信息。具有连接监控中心功能的终端称为网关(GW)。多跳功能用于连接gw;这降低了连接广域无线网络的成本。然而,安装新终端的顺序是随机的,因为它是由个别家庭更换电表的时间决定的。因此,无法提前确定gw的安装位置。因此,任何创建的网络拓扑都会出现冗余,例如不必要的gw,或者生成许多小型网络。本文提出了两种不同的冗余减少方法,利用云上终端的信息重构网络拓扑结构。提出的方法包括三个步骤:收集信息,利用云模拟拓扑以减少冗余,提供反馈以重建每个智能电表的信息。我们进行了计算机模拟,以评估分组传输率(PDR)和GWs数量的减少率。我们证实,使用所提出的方法可以在不影响网络拓扑性能的情况下减少冗余。

The end-user integration for M2M application service creation and the decentralisation of M2M application service platforms are creating new possibilities for different application fields in the M2M domain. However, besides several advantages, these improvements inherit several security-related issues such as intentionally or accidentally misconfigured M2M application services harming other end-users in the M2M community. This research focuses on evaluating the trustworthiness of new joining decentralised M2M application services provided by end-users. Therefore, this publication presents a novel concept for trust evaluation by combining several model-based testing techniques. Moreover, it defines an approach for trust-based M2M application service selection and composition for end-user consumption. Finally, the overall framework for functional verification and trust evaluation is optimised by full decentralisation of all involved entities.
M2M应用服务创建的终端用户集成和M2M应用服务平台的分散化为M2M领域的不同应用领域创造了新的可能性。然而,除了一些优点之外,这些改进还继承了一些与安全相关的问题,例如有意或无意地错误配置M2M应用程序服务,从而损害了M2M社区中的其他最终用户。本研究的重点是评估终端用户提供的新加入的分散式M2M应用服务的可信度。因此,本文结合几种基于模型的测试技术,提出了一种新的信任评估概念。此外,它还定义了一种用于最终用户消费的基于信任的M2M应用程序服务选择和组合的方法。最后,通过所有相关实体的完全去中心化,优化了功能验证和信任评估的总体框架。

End-to-end Internet Quality of Service (QoS) is likely to rely on the hop count, the number of traversed routers. In this paper, we pose the results of the measurements of hop count from a source at Keimyung University towards several destinations spread over the world by using both active and passive measurements. In case of active data, we used traceroute base inferring to measure hops between host IP-addresses, while for passive data, we utilise shortest path approach from BGPview AS graph to infer exact hop count between ASes.
端到端互联网服务质量(QoS)很可能依赖于跳数,即穿越路由器的数量。在本文中,我们通过使用主动和被动测量,对来自启明大学的一个源对分布在世界各地的几个目的地的跳数进行了测量。在主动数据的情况下,我们使用traceroute基推断来测量主机ip地址之间的跳数,而对于被动数据,我们使用BGPview AS图中的最短路径方法来推断AS之间确切的跳数。

In this paper, we proposes a novel drowsiness detection algorithm using a camera near the dashboard. The proposed algorithm detects the driver's face in the image and estimates the landmarks in the face region. In order to detect the face, the proposed algorithm uses an AdaBoost classifier based on the Modified Census Transform features. And the proposed algorithm uses regressing Local Binary Features for face landmark detection. Eye states (closed, open) is determined by the value of Eye Aspect Ratio which is easily calculated by the landmarks in eye region. The proposed algorithm provides realtime performance that can be run on the embedded device. We obtained the dataset using video records from the infrared camera which is used the real-field. The proposed algorithm tested in the target board (i.mx6q). The result shows that the proposed algorithm outperformed in the speed and accuracy.

In October 1999 a long-range underwater acoustic communication experiment was conducted in East Sea of Korea. In this experiment, horizontal distance between a transmitter and receiving array was 559.25 km. The transmitted signals were 511-digit m sequence with a center frequency of 366 Hz and a bandwidth of 45.75 Hz, and the modulation type was binary phase shift keying. In order to compensate inter-symbol interference, maximal ratio combining and equalization are adopted sequentially. As a result, 0.01 of uncoded bit error rate is obtained at a data rate of 37.2 bit per second.

Though the use of internet of things (IoT) technology is increasing, it is difficult to reuse application program once implemented because of various kinds of device and platform. In order to solve these problems, a method of using a virtual machine in an IoT device has been proposed. However, there is a disadvantage that the execution speed of the application program is very slow compared to the native code due to the characteristics of the virtual machine. Ahead-of-Time (AoT) compilation is a technique that precompiles bytecodes into native code to speed up execution of virtual machines. In this paper, we design the AoT compilation system for IoT-Cloud virtual machine system. The designed system is suitable for the convergence environment of the IoT and the cloud. Since only a portion of the bytecode is compiled into native code, the memory load of the virtual machine required for loading native code is reduced.
虽然物联网技术的应用越来越多,但由于设备和平台的多样性,应用程序一旦实施就很难重用。为了解决这些问题,提出了一种在物联网设备中使用虚拟机的方法。但是,由于虚拟机的特性,应用程序的执行速度与本机代码相比非常慢。提前编译(AoT)是一种将字节码预编译为本机代码以加快虚拟机执行速度的技术。本文设计了面向物联网云虚拟机系统的AoT编译系统。设计的系统适用于物联网与云的融合环境。由于只有一部分字节码被编译为本机代码,因此减少了加载本机代码所需的虚拟机内存负载。

In this paper, we propose a novel pseudo-random beamforming technique with beam selection for improving physical-layer security (PLS) in a downlink cellular network where consists of a base station (BS) with Nt antennas, NMS legitimate mobile stations (MSs), and NE eavesdroppers. In the proposed technique, the BS generates multiple candidates of beamforming matrix each of which consists of orthogonal beamforming vectors in a pseudo-random manner. Each legitimate MS opportunistically feeds back the received signal-to-interference-and-noise ratio (SINR) value for all beamforming vectors to the BS. The BS transmits data to the legitimate MSs with the optimal beamforming matrix among multiple beam forming matrices that maximizes the secrecy sum-rate. Simulation results show that the proposed technique outperforms the conventional random beamforming technique in terms of the achievable secrecy sum-rate.
在本文中,我们提出了一种新的带波束选择的伪随机波束形成技术,用于提高由Nt天线基站(BS)、NMS合法移动站(ms)和网元窃听器组成的下行蜂窝网络中的物理层安全性(PLS)。在该技术中,BS以伪随机方式生成多个候选波束形成矩阵,每个候选波束形成矩阵由正交波束形成向量组成。每个合法的MS都会将接收到的所有波束形成矢量的信噪比(SINR)值反馈给BS。在多个波束形成矩阵中,采用最优波束形成矩阵将数据传输到合法的MSs,使保密和速率最大化。仿真结果表明,该方法在可实现的保密性和速率方面优于传统随机波束形成技术。

The highway junction point, where the ramp is merged with the mainstream, is the main traffic congestion point in the highway when handling transport demands. A vehicle driving on the ramp generally attempts to enter the highway without predicting the traffic condition, and commonly causes traffic congestion on highways. Traffic congestion in the highway junction is defined as the traffic situation that the transport demand in the conjunction point exceeds the bottleneck capacity and the accumulated demand remains to the bottleneck. Under traffic congestion, vehicles driving on the ramp cannot efficiently enter the highway. As a result, the waiting time of the vehicle on the ramp becomes long, and fuel consumption and CO2 emission increase due to the frequent acceleration and deceleration. In this paper, we propose a vehicular speed acceleration advisory algorithm for the vehicle on the ramp at the junction point. By recognizing the traffic condition on highways using V2V (Vehicle-to-Vehicle) communication, the proposed algorithm helps to reduce the frequent acceleration and deceleration by drivers. From the simulation results, compared to the conventional driving on the ramp, we show that the proposed algorithm can decrease fuel consumption, CO2 emission under various vehicle densities.
高速公路交汇点是匝道与主流交汇的地方,是高速公路处理运输需求时的主要交通拥堵点。在坡道上行驶的车辆通常在没有预测交通状况的情况下试图进入高速公路,这通常会造成高速公路上的交通拥堵。公路交叉口的交通拥堵定义为交叉口的运输需求超过瓶颈容量,且累计需求仍停留在瓶颈处的交通状况。在交通拥堵情况下,在匝道上行驶的车辆无法有效进入高速公路。因此,车辆在坡道上的等待时间变长,并且由于频繁的加减速而导致油耗和二氧化碳排放量增加。在本文中,我们提出了一种交叉口匝道上车辆的车速加速度咨询算法。该算法通过V2V (Vehicle-to-Vehicle)通信识别高速公路上的交通状况,有助于减少驾驶员频繁的加速和减速。仿真结果表明,与传统坡道行驶相比,该算法在不同车辆密度下均能有效降低车辆的油耗和CO2排放。

Energy management system should predict the future energy use and generation amount for the optimal operation of ESS based on the measured energy amount, renewable energy production amount and energy usage, and establish the operation plan. In this paper, we describe the technologies that can be saved through the analysis of big data of energy resources for renewable energy and present Demand Response Operation Method through big data analysis. Through this technology, it is possible to find new information by discovering patterns and correlations hidden in data, and to respond appropriately when issuing DR.
能源管理系统应根据实测的能源总量、可再生能源产生量和能源使用情况,预测未来ESS优化运行的能源使用量和发电量,并制定运行计划。本文通过对可再生能源能源资源大数据的分析,阐述了可节省的技术,并通过大数据分析提出了需求响应运行方法。通过这种技术,可以通过发现隐藏在数据中的模式和相关性来发现新的信息,并在发布DR时做出适当的响应。
