RF can provide a non-contact and non-line-of-sight of sensing of the physical world, therefore, it makes RF unique sensing modality that has found applications in automotive sensing, smart-home sensing, health monitoring, and many other applications. ...

In this paper, we propose a mathematical model that aims at prolonging the lifetime of sensor networks via an adaptive cluster head placement technique. We consider Transmit-Only (TO) sensor networks, where each group of sensor nodes directly ...

The end-to-end distribution of real-time 360-degree video needs to be evaluated in a wholesome manner, considering all aspects from video capture to encoding, delivery, and playback, as well as timely and appropriate analytics, with a focus on end-user ...

Built on top of the Long Range (LoRa) physical layer, the LoRa Wide-Area Network (LoRaWAN) protocol has recently emerged as one of the most promising Low-Power Wide-Area Network (LPWAN) technologies, for several Internet of Things (IoT) applications. ...

Large-scale emergencies, both natural and man-made, are increasingly incurring devastating losses in terms of infrastructure and human lives. Rural areas, with their unique socio-economic structure, are particularly vulnerable to such losses. Emergency ...

We propose a QoE-based analysis approach for real-time adaptive 360-degree video streaming measurements, focusing on the correlation between objective video metrics and subjective end-user scores.

During the first half of this year, three major operators in the US have announced their 5G deployment, which indicates the advent of next generation networks. To reduce the time to market, carriers utilize 5G NR for data plane operations while ...

Low Power Wide Area Networks (LPWAN) desire 1) energy efficiency, 2)long communication range, and 3) scalability for ubiquitous connectivity. Existing technologies any two and trade off the third. We propose a differential time modulation that is energy ...

The load on wireless cellular networks is not uniformly distributed through the day, and is significantly higher during peak-times. In this context, we present a time-shifted prefetching solution that prefetches content during off-peak periods of ...

Fog computing recently emerged as a novel distributed virtualized computing paradigm, where cloud services are extended to the edge of the network, thereby increasing network capacity and reducing latencies for distributed IoT applications. A fog ...

The multi-Gbps bandwidth offered by 60GHz millimeter-wave (mmWave) links has enabled a wide range of applications such as untethered virtual reality, fast file synchronization, and uncompressed video streaming. To provide these applications with high ...
