In this paper we present a selection from a vast range of experiments run with MONROE, our experiment as a service platform open to external researchers. We show that the platform can be used to benchmark network performance in a repeatable and ...

This paper presents cniCloud, a cloud platform for mobile devices to share and query the fine-grained cellular information at scale. cniCloud extends the single-device cellular analytics via crowdsourcing: It collects the fine-grained cellular network ...

Connected vehicle applications promise to transform traffic management and safety. Evaluating the performance of vehicular communication systems in real-world settings benefits from detailed propagation models. Developing such models can be challenging ...

Safety messaging for connected vehicles imposes both challenging workloads and stringent robustness requirements on wireless networks. In particular, the design and validation of communication protocols that can operate under high node densities has ...

Mobile traffic demand is expected to grow as much as eight-fold in the coming next five years, putting strain in current wireless infrastructure. One of the most common means for matching these mounting requirements is through network densification, ...

This paper presents Virginia Tech's wireless testbed supporting research on long-term evolution (LTE) signaling and radio frequency (RF) spectrum coexistence. LTE is continuously refined and new features released. As the communications contexts for LTE ...

The availability of very cheap RTL-SDR "dongle" devices has unleashed the popularity of Software-Defined Radio (SDR) projects in the last years, both among academics and hobbyists. The main success factors are the very affordable price ($25 USD), ease ...

The most widespread Wi-Fi enabled devices are smartphones. They are mobile, close to people and available in large quantities, which makes them perfect candidates for real-world wireless testbeds. Unfortunately, most smartphones contain closed-source ...

We propose a probabilistic packet reception model for Bluetooth Low Energy (BLE) packets in indoor spaces and we validate the model by using it for indoor localization. We expect indoor localization to play an important role in indoor public spaces in ...

This paper introduces X60, the first SDR-based testbed for 60 GHz WLANs, featuring fully programmable MAC/PHY/Network layers, multi-Gbps rates, and a user-configurable 12-element phased antenna array. Combined these features provide an unprecedented ...

The energy restricted nature of underwater sensor networks directly affects the expected lifetime of autonomous deployments and limits the capabilities for long term underwater monitoring. Towards the goal of developing energy-efficient protocols and ...

Target material identification plays an important role in many real-life applications. This paper introduces a system that can identify the material type with cheap commercial off-the-shelf (COTS) RFID devices. The key intuition is that different ...

This demo paper presents FLEX-MONROE, a platform that facilitates better understanding of the status of current Mobile Broadband (MBB) networks (e.g. 3G and 4G/LTE) and enables performance improvements by allowing experimentation with controllable LTE ...

Typical wireless sensor network applications follow duty-cycle mechanisms, yielding important energy savings by reducing the power consumption of idle listening. However, this approach still dictates predefined cycles of active operation, which in some ...

Typical wireless sensor devices feature an extreme power consumption range between their active and sleep states, thus requiring different hardware setups for measuring their expenditure with high accuracy. In this demo paper we present the NITOS ...

Radio frequency (RF) spectrum is transitioning from exclusive licensed to shared use in many bands. We demonstrate our design and implementation of a spectrum access system (SAS), which allows centrally coordinated access to shared spectrum. It shows ...

Smartphones and Internet of Things (IoT) devices are widely available and offer interfaces for wireless communication. This makes them perfect candidates for large-scale wireless testbeds. To reduce energy consumption, those devices contain FullMAC Wi-...

We integrate a prototype WiFi Time-of-Flight (ToF) ranging and positioning system in the WiSHFUL software platforms and hardware radios for experimental prototyping. Users can have access to ToF measurements as well as computed positions through unified ...
