Hybrid Broadcast Broadband TV (HbbTV) is an industry standard for hybrid multimedia devices that are able to combine broadcast and IPTV delivery. This paper deals with companion screen devices, companion screen applications and communication of those applications with HbbTV terminal and its applications. Companion screen devices offer additional content to user and for pleasant experience communication...
Internet of vehicles (IoVs) emerges as a promising technology to facilitate vehicular wireless communication by approving vehicle-to-everything (V2X) services for intelligent transportation systems including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) services. V2V networks have been rapidly developed to support short distance data transmission among vehicles...
Increasing amounts of data from varied sources, particularly in the fields of machine learning and graph analytics, are causing storage requirements to grow rapidly. A variety of technologies exist for storing and sharing these data, ranging from parallel file systems used by supercomputers to distributed block storage systems found in clouds. Relatively few comparative measurements exist to inform...
Inter-process communication (IPC) is one of the crucial aspects of every microkernel. The message-passing interface (MPI) is a specification between different processes, which is used for communication amongst processes. Message Passing Interface Chameleon (MPICH) is the portable implementation of message passing interface. This paper delineates the comparison between IPC, MPI and MPICH in terms of...
Network performance anomalies can be defined as abnormal and significant variations in a network's traffic levels. Being able to detect anomalies is critical for both network operators and end users. However, the accurate detection without raising false alarms can become a challenging task when there is high variance in the traffic. To address this problem, we present in this paper a novel methodology...
With the increasing technological complexity modern SoC designs continue to grow in size and involve increasingly more IPs. Therefore, it becomes much harder to complete testing of large SoCs within the desired schedule and cost. Usually an automated hierarchical test helps to solve this problem efficiently but for such systems the preparation of input data, especially IP level information and description...
Internet of Thing (IoT) is growing rapidly with more devices connected to the Internet. One emerging group of these is called wearable devices. The wireless technologies used by wearable devices need to consider the long lasting of battery life. Consequently, Bluetooth Low Energy (BLE) has emerged as the wireless technologies for wearable devices due to its features of low power consumption. In this...
The operation and maintenance of large distributed systems that are subject to high QoS conditions has led to the need of designing and developing advanced monitoring tools that facilitate the administration of the critical services required by the user communities. RASSMon is a portable, reliable, secure software platform able to collect monitoring data from multiple sources in heterogeneous environments...
In this paper, a hybrid broadcast broadband TV (HbbTV) test system with the automatic testing subsystem is proposed. The proposed system is based on Node.js framework with SQLite database on the backend side and Polymer framework on the front-end side. The paper covers basic testing metodology and design process with the emphasis on the implementation and testing.
In this Web 2.0 era, billions of social media users contribute massive amounts of information that have already been presented in earth observation (EO) applications such as earthquake information reporting, flood monitoring, and wildfire alerting. Nevertheless, applying social media data in geo-sensing missions directly and effectively remains a challenge. In this paper, we examine how to design...
Battery Simulator is a kind of test equipment commonly used in satellite power, electric vehicles and other power application fields. Design a battery simulator with a standard LXI bus interface is important for building a multi-instrument test system. This paper puts forward a SCPI instruction analytical platform based on LXI bus. Remote PC sends SCPI command over LXI bus. The communication board...
Detecting RAT (Remote Access Trojan or Remote Administration Tool) used in APT (Advanced Persistent Threat) attacks is a challenging task. Many previous methods to detect RATs on the network require monitoring all network traffic. However, it is difficult to keep all network traffic because the size is too huge. Actually, we would have to detect RAT activity through insufficient information such as...
The IoT/M2M service providers need security mechanisms to avoid illegal usage of the service. Normally, this can be accomplished by using the certificate to authenticate the device before providing the service. In this paper, we consider the situation where a malicious user attempts to pay only for the service of a device but deploy the same certificate for many other devices to access the service...
Video streaming now amounts to the majority of traffic in the Internet. Media streaming relies on large-scale content distribution networks (CDNs), that incur significant costs to build or use. P2P distribution of video content reduce reliance on CDNs and costs. Unfortunately, P2P distribution is fraught with QoE problems, specially during flash crowds or in scenarios where users have limited bandwidth...
High quality of the provided communication services can be reached by package networks by the organization of network synchronization of the time scales (TS). The report summarizes the experience of comparing the TS of the leading watches of the corporate telecommunication network with the state time scale - UTC (SU). The methods of realization of checking of a time scale and methods of distribution...
Cloud computing has gained popularity in recent years due to its pay-as-you-go business model, high availability of services, and scalability. Service unavailability does not affect just user experience but is also translated into direct costs for cloud providers and companies. Part of this costs is due to SLA breaches, once interruption time greater than those signed in the contract generate financial...
While the Internet of Things is breaking into the market, the controlled access to constrained resources still remains a blocking concern. Unfortunately, conventional solutions already accepted for both web and cloud applications cannot be directly used in this context. In fact, they generally require high computational and bandwidth capabilities (that are impossible to reach with constrained devices)...
This paper presents the architecture and technologies used to develop a voice controlled system for home automation named Cassandra. We start with the goals of the project and a system description, then focusing on the main components and the way they interact with each other. We exemplify with a scenario where we ask the house to turn the lights off, going step-by-step over the communication sequence...
Programmable Logic Controllers (PLCs) are specialized computing systems for the control and monitoring of distributed industrial devices. Aiming for a highly connected industrial Internet-of-Things (IoT) ecosystem, PLCopen OPC Unified Architecture (UA) specification has been released. This paper presents the implementation and evaluation of a PLCopen OPC-UA software component for industrial control...
With the increase in the number of cars in big cities, it has become a nightmare for car owners to find available parking spaces. Some studies report that around 25-30% traffic on the roads are cars finding available spaces for parking. While many researches have been conducted to create a smart parking system, most of them only focus on some particular areas and environments without any common standards...
