There is a definite upward trend in the number of cellular communication nodes that, together with high rate of digital content transactions, led to continuous progress on generational technologies (3G, 4G, 5G, and more recently 6G). To facilitate ...

In this paper, we demonstrate OmniCells: a cellular-based indoor localization system designed to combat the device heterogeneity problem. OmniCells is a deep learning-based system that leverages cellular measurements from one or more training devices to ...

SMS-based two-factor authentication (2FA) is the most widely deployed 2FA mechanism, despite the fact that SMS messages are known to be vulnerable to rerouting attacks, and despite the availability of alternatives that may be more secure. This is for ...

In order to solve the problem that the existing living cell microscopy technology can not display the detailed information of cells, a high sensitivity digital holographic living cell microscopy technology is proposed in this paper. By measuring ...

The use of mobile devices for Internet usage has been rapidly increasing and thus the demand for wireless networks. There have been plenty of scenarios and cases that mobile consumers and businesses get into areas that do not have a reliable wireless ...

The use of Unmanned Aerial Vehicles (UAVs) is becoming common in our daily lives and cellular networks are effective in providing support services to UAVs for long-range applications. The main target of this paper is to propose a modified form of well-...

Advertisers gather data about users and their mobile devices through ads placed within Android and iOS apps. Most of the time, location, device, and app information are linked to the same device using a unique advertising ID (Ad ID). If the Ad ID is not ...

Rogue base stations are an effective attack vector. Cellular basebands represent a critical part of the smartphone's security: they parse large amounts of data even before authentication. They can, therefore, grant an attacker a very stealthy way to ...

We present BurstTracker, the first tool that developers can use to detect if the LTE downlink is the bottleneck for their applications. BurstTracker is driven by our discovery that the proprietary LTE downlink schedulers running on LTE base stations ...

MP-H2 is a client-only, HTTP-based multipath solution. It enables an HTTP client to fetch content (an HTTP object) over multiple network paths such as WiFi and cellular on smartphones. Compared to MPTCP, MP-H2 offers several key advantages including ...

The demand for a ubiquitous and accurate indoor localization service is continuously growing. Cellular-based systems, by definition, have been shown to be a perfect selection to provide a ubiquitous localization service. The main barrier towards ...

Thanks to the wide availability of bandwidth, the millimeter wave (mmWave) frequencies will potentially provide very high data rates to mobile users in next generation 5G cellular networks. However, mmWave links suffer from high isotropic pathloss and ...

Connected cars are a rapidly growing segment of Internet of Things (IoT). While they already use cellular networks to support emergency response, in-car WiFi hotspots and infotainment, there is also a push towards updating their firmware over-the-air (...

HTTP Adaptive Streaming (HAS) has emerged as the predominant technique for transmitting video over cellular for most content providers today. While mobile video streaming is extremely popular, delivering good streaming experience over cellular networks ...

We consider the problem of managing Firmware Over-The-Air (FOTA) updates for cars at a massive scale over a cellular network. This problem is constrained by factors like large number of cars, a need to perform updates quickly and securely, ability to do ...

The rapid growth in mobile connectivity is enabling phones to support a wide range of societally-important applications. In this work, we show that broad classes of popular mobile applications have distinct radio resource allocation signatures. Using ...

The demands for mobile communication is ever increasing. Mobile applications are increasing both in numbers and in heterogeneity of their requirements, and an increasingly diverse set of mobile technologies are employed. This creates an urgent need for ...

Highly dynamic vehicular networks use long-range radio technologies such as DSRC, WiMAX, and Cellular networks to maintain connectivity. Multipath TCP offers the possibility to combine these radio technologies to improve network performance, allow ...

Compared with using only a single wireless path such as WiFi, leveraging multipath (e.g., WiFi and cellular) can dramatically improve users' quality of experience (QoE) for mobile video streaming. However, Multipath TCP (MPTCP), the de-facto multipath ...

The transition to IPv6 cellular networks creates uncertainty for content providers (CPs) and content delivery networks (CDNs) of whether and how to follow suit. Do CPs that update their CDN contracts to allow IPv6 hosting achieve better, or worse ...
