Millimeter-wave (mm-wave) frequencies are seen as the new frontier in enabling high capacity for 5G-and-beyond cellular networks. However, spatio-temporal variations of the mm-wave channel impose significant challenges for high rate error-free ...

Line-of-sight (LOS) is a critical requirement for mmWave wireless communications. In this work, we explore the use of access point (AP) infrastructure mobility to optimize indoor mmWave WiFi network performance based on the discovery of LOS connectivity ...

In modern society, vehicles have become an indispensable means of transportation to ensure people's travel and the circulation of social production materials and living materials. However, while bringing us convenience in life, with the increasing ...

Over the past few months, COVID-19 has emerged to the world as a new threat to humanity and communities, expanding from a few small infected cities to hundreds of countries around the world impacting businesses, education, economics, and almost every ...

Crowd monitoring and management is an important application of Mobile Crowdsensing (MCS). The emergence of COVID-19 pandemic has made the modeling and simulation of community infection spread a vital activity in the battle against the disease. This ...

In this paper, Vecsim, a novel contact tracing method, is proposed. Vecsim determines the user proximity based on the existing log data already collected by the cellphone network carrier for network management purposes, and is transparent to the users. ...

Vehicular communications suffer from intermittent connectivity due to sudden topology changes. Content retrieval is based on broadcasting and/or cellular infrastructure that allows vehicles to download or upload content. This paper investigates how ...

Urban mobility has become a topic of interest, since the number of vehicles in large cities constantly increases and traffic jams take away from people an increasingly amount of time from their day. We explored an Uber data set with trips from Lima, ...

In recent years, in the face of the increasingly complicated traffic environment caused by the significant increase in the number of motor vehicles, in order to improve road traffic safety, autonomous driving technology has become the focus of research, ...

Mobile networks have become ubiquitous and the primary means to access the Internet, and the traffic they generate has rapidly increased over the last years. The technology and service diversity in mobile networks call for extensive and accurate ...

Multi-SIM capable mobile phones have been gaining popularity. Due to the absence of standardized solution, there are implementation variations in the User Equipment (UE) from both hardware and software perspectives. Especially, coordination of call ...

Internet connectivity on aircraft is becoming more and more popular, while its performance is lacking behind the offer on ground. In order to provide a high throughput to aircraft, an air-to-ground network combining direct air-to-ground, satellite and ...

Followed by the destruction of existing infrastructure or the emergence of the necessity for a new infrastructure, disaster events (e.g., earthquakes and pandemic) may require inspection of certain area and passing information to a dedicated help unit. ...

Integrity of location data from smart-phones is essential in several location-dependent applications. Unfortunately it is quite easy to spoof location data on smart phones. Therefore, most mission critical services such as road-side assistance, use ...

We present a simulation-based assessment of the performance potential of distributed MIMO (D-MIMO), multi-user MIMO (MU-MIMO) and particularly the combined D/MU-MIMO operation, for which we extend previously published scheduling and beamforming ...

The Internet of Things (IoT) is a relatively new concept with a number of potential uses in agriculture. In this work we propose a system based on IoT for early detection of wine moth infestation, as well as monitoring the number of pests at a ...

The disruptions caused by Network Function Virtualization (NFV) and Software Defined Networking (SDN) introduce severe impacts also on mobility management. In this work, we will show how IP-based mobility management, especially Mobile IPv6 (MIPv6), can ...
