The authors present a series of sea trails with autonomous systems using a long-range communication network. The continuous monitoring of the oceans and realtime data gathering/monitoring is a key issue in future marine challenges. To have long range communication, between land and ships at tens of kilometers', the authors used the BlueCom+ project research trials and tested their robotic systems...
The Tactile Internet refers to the communication networks that have a closed control loop of tactile input and audio and/or visual feedback. Example applications include telerehabilitation and virtual training. To ensure that these applications have unnoticeable latencies and thus satisfied quality-of-service and quality-of-experience requirements, the Tactile Internet needs to guarantee round-trip...
In this work, the principal aim is establishing networks parameters of wireless sensor. These devices can transmit variables to monitoring the quality of tourist beaches in the Colombian Caribbean. We propose a methodology to choose the network elements and its technologies. We analysis data based on coverage and implement the prototype. We show that the maximum distance between nodes is 33 m at mesh...
The Internet of Things (IoT) is becoming important in many areas that include health, entertainment, manufacturing, automotive, home and building automation, industrial, etc. Will it be important for education and more specifically for teaching and learning? If so, what engineering subjects would benefit the most and how effective could the IoT be for teaching and learning? Can IoT technologies and...
Wireless communication technology is spreading rapidly to all areas of our lives. The technology, which has a wide range of applications from radios, intelligent home systems, automation applications to GPS units, was used in monitoring the workers working in mines in this study. Most of the mining area underground mining is risky and the possibility of accident (gas jams, the explosion and dents,...
Accessing the Internet through Wi-Fi networks offers an inexpensive alternative for offloading data from mobile broadband connections. Businesses such as fast food restaurants, coffee shops, hotels, and airports, provide complimentary Internet access to their customers through Wi-Fi networks. Clients can connect to the Wi-Fi hotspot using different wireless devices. However, network administrators...
Internet of Things (IoT) has revolutionized the traditional Internet where only human-centric services were offered. It has enabled objects to have the ability to connect and communicate through the Internet. IoT has several applications such as smart water management systems. However, they require high energy-efficient sensor nodes that are able to communicate across long distance. This motivates...
The increased popularity of IEEE 802.11 LANs (WLANs) in residential (home) environments leads to dense, unplanned and thus chaotic deployments. Access Points (APs) are frequently deployed unfavorably in terms of radio coverage and use interfering frequency/power settings. In fact, in some parts of a one's apartment the usage of the neighbor's AP might be preferred as it might provide better signal...
Internet of Things (IoT) uses the connection between devices to improve their efficiency and user experience, being the communication one of the main elements for a proper IoT network. This paper presents a review of the most common wired and wireless communication protocols, discusses their characteristics, advantages and disadvantages as well as a comparison study to choose the best bidirectional...
Today, the cyber-world is fast growing to support almost all activities of humans. Moreover, the cyber-world begins to be self-contained so that we can perform every activity in the cyber-world. Although the term "cyber-physical world" is still in use, we see that the "cyber" part is fast growing.In the cyber-world, devices scattered in the physical world play a critical role....
This paper will discuss the distributed caching strategies in clustered heterogeneous cellular networks. Basically, there are two obstacles to accomplish the caching policy in the wireless access networks, i.e., the limited storage capacity of small cells and the too small coverage area of each base station to imply content aggregation effect. Traditionally, the existing caching strategies only concern...
In this paper, we call for a paradigm shift away from the wireless-access focused research efforts on 5G networked systems. We believe that the architectural limitations should share equal blame on issues of performance, reliability, and security. We thus identify architectural weakness on both sides of the mobile clients and the 4G network infrastructure. Our recent findings show that, contrary to...
Global Energy Internet is one of the hottest research fields recently. It is a further development and enhancement of the smart grid system. However, the energy Internet is different from the smart grid in several aspects. Energy Internet is a new type of ecological energy system that is integrated with traditional energy system when the information has evolved into a new means of production, especially...
The aim of the paper has been to make individuals with disability in arms, who have been fed during meals, completely or partially independent by use of the self-feeding device. In this paper, it describes a self-feeding system designed to increase the independence of a person who is unable to use their arm for self-feeding. It is FeedBot, a highly integrated and compact service robot with manipulator...
With the rapid development of new applications and services in vehicular environment, there is an increasing demand for mobile users to access data items. Moreover, Road Side Unit (RSU) has been introduced by researchers to facilitate data dissemination in Vehicular Ad-hoc Networks (VANETs). Therefore, it is necessary to design a data access scheme for vehicle-to-roadside (V2R) communications. However,...
Large online video sharing systems are becoming increasingly prevalent among the general public recently. A better understanding of their service usages is crucial for allocating the network resources and adjusting the service design. In this paper, we focus on a leading online video sharing system in China, namely Youku. We collected over 12 billion traffic traces from the network operator, and crawled...
In the recent years it has become increasingly evident that the current end-to-end host-centric communication paradigm will not be capable of meeting the ongoing demand for massive data rates and ultra-low latency. With the advent of fifth generation of cellular architecture (5G) to support these requirements on the wireless edge of the network, the need for core network solutions to play a complementary...
Controlling robots in real-time over a wireless interface present fundamental challenges for forthcoming fifth generation wireless networks. Mission critical real-time applications such as telesurgery over the tactile Internet require a communication link that is both ultra-reliable and low-latency, and that simultaneously serving multiple devices and applications. Wireless performance requirements...
Conflagration is one of the major disasters that threatens human life and property. If the proper action is not taken in detecting the symptom of conflagration events ahead of time, the number of such disasters will keep increasing. An effective solution in this context will alleviate many fire-related global problems to a great extent. Although fire detectors are not available in many places, WiFi...
This work describes a clean-slate inter-domain routing protocol designed to meet the needs of the future mobile Internet. In particular, we describe the edge-aware inter-domain routing (EIR) protocol which provides new abstractions of aggregated-nodes (aNodes) and virtual-links (vLinks) for expressing network topologies and edge network properties necessary to address next-generation mobility related...
