Vehicle-to-Vehicle (V2V) communication is an essential component of the Intelligent Transportation System (ITS), which enables realtime traffic data sharing and collective awareness among vehicles and promotes a safer, more effective, and ...

There have been many papers that show the physical layer advantages of beamforming. However, to the best of our knowledge, none have dealt with the large-scale network level performance evaluation. While it is clear that beamforming brings a positive ...

Currently, most videoconferencing technologies do not keep employees sufficiently engaged during business meetings. Recent studies have shown how extended reality (XR) technologies can help in executing remote meetings in new and possibly better ways. ...

In the domain of automated driving, numerous (technological) problems were solved in recent years, but still many limitations are around that could eventually prevent the deployment of automated driving systems (ADS) beyond SAE level 3. A remote ...

Cloud services have recently started undergoing a major shift from monolithic applications, to graphs of hundreds or thousands of loosely-coupled microservices. Microservices fundamentally change a lot of assumptions current cloud systems are designed ...

In this paper, we investigate the performance gains that are achievable when jointly controlling (i) in which Small-cell Base Stations (SBSs) mobile users are associated to, (ii) which content items are stored at SBS co-located caches and (iii) which ...

Parking lots in densely crowded environments such as stadiums, theaters, and hospitals provide great opportunities for vehicular cloud services. A cloud environment formed by individual vehicles, where each vehicle offers its resources as a service has ...

In Wireless Sensor Networks (WSNs), each node typically transmits several control and data packets in a contention fashion to the sink. In this work, we mathematically analyze and study three unscheduled transmission schemes for control packets in a ...

In this paper, we propose QoS based radio resource allocation, where multi modal users are capable to connect to multi-RATs in heterogeneous wireless access network (HWAN). Our optimization problem is based on system sum-rate maximization under the QoS ...

The Internet of Thing is an ongoing revolution which promises to interconnect most of our world with billions of connected devices. Hence, data routing and prioritization in IoT is a main challenge in this gigantic network. This is all the more true for ...

In our work we analyze the network traffic generated by a small low-cost quadcopter. In particular, we consider the IEEE 802.11n protocol focusing on the live video streaming communication between the UAV and its controller in different outdoor ...

In the last few years, several processing approaches have emerged to deal with Big Data. Exploiting on-the-fly computation, Data Stream Processing (DSP) applications can process unbounded streams of data to extract valuable information in a near real-...

The aim of this work is to present the problem of Capacity Allocation for multiple classes of Big Data applications running in the Cloud. The objective is the minimization of the renting out costs subject to the fulfillment of QoS requirements expressed ...

Docker containers enable to package an application together with all its dependencies and easily run it in any environment. Thanks to their ease of use and portability, containers are gaining an increasing interest and promise to change the way how ...

Remote access to NVMe Flash enables flexible scaling and high utilization of Flash capacity and IOPS within a datacenter. However, existing systems for remote Flash access either introduce significant performance overheads or fail to isolate the ...

Wireless LANs (WLANs) carry a diversemix of traffic, ranging from delay-sensitive real-time applications to bulk transfers. Using existing QoS mechanisms in high speed WLANs (e.g., 802.11n/ac) presents a tradeoff between maximizing the performance of ...

This paper concerns the use of Active Queue Management (AQM) to reduce queuing delay. It offers insight into why it has proved hard for a Proportional Integral (PI) controller to remain both responsive and stable while controlling `Classic' TCP flows, ...

In this paper we present a novel prospective of virtual private networks built upon the fourth generation smallcell technology. The proposed solution promotes the enterprise manageability on its private connections, users' mobility, and QoS provisioning,...

The fourth generation of mobile networks, known as Long Term Evolution (LTE), is the first 3GPP cellular fully-IP standard. Quality of Service (QoS) policies are based on bearers and QoS Class Identifier (QCI). Here we focus on Quality of Experience (...

Network Function Virtualisation (NFV) represents a promising solution for wireless network operators to improve business agility and cope with the continuing growth in data traffic. Furthermore, by virtualizing core network functions as well as radio-...
