Motivated by the rapid deployment of 5G, we carry out an in-depth measurement study performance, power consumption, and application quality-of-experience (QoE) commercial 5G networks in wild. We examine different carriers, schemes (Non-Standalone, NSA vs. Standalone, SA), radio bands (mmWave sub 6-GHz), protocol configurations (_e.g._ Radio Resource Control state transitions), mobility patterns (stationary, walking, driving), client devices (_i.e._ User Equipment), upper-layer applications...
With 5G's support for diverse radio bands and different deployment modes, e.g., standalone (SA) vs. non-standalone (NSA), mobility management - especially the handover process becomes far more complex. Measurement studies have shown that frequent handovers cause wild fluctuations in 5G throughput, worst, service outages. Through a cross-country (6,200 km+) driving trip, we conduct in-depth measurements to study current practices adopted by three major U.S. carriers. Using this rich dataset,...
Cooperative perception significantly enhances the performance of connected autonomous vehicles. Instead purely relying on local sensors with limited range, it enables multiple vehicles and roadside infrastructures to share sensor data perceive environment collaboratively. Through our study, we realize that cooperative systems is in real-world deployment due (1) out-of-sync during fusion (2) inaccurate localization occluded areas. To address these challenges, develop RAO, an innovative,...
Neural-enhanced video streaming (e.g., super-resolution) is an ongoing revolution which can provide extremely high-quality services breaking the restriction of bandwidth. However, such enhancements require intense computation power that not affordable for a single mobile device, hinders their real-world deployment. To address limitation, we propose OASIS, first system facilitates multiple users in close proximity to execute neural-enhanced realtime. this end, OASIS intelligently distributes...
Collaborative Vehicular Perception (CVP) enables connected and autonomous vehicles (CAVs) to cooperatively extend their views through wirelessly sharing sensor data. Existing CVP systems employ either a vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) view exchange paradigm. In this paper, we advocate hybrid design: our developed system, Harbor, employs V2I as its fundamental underlying framework, opportunistically V2V boost the performance. (helpers) may serve relays assist other...
5G and future 6G networks support diverse combinations of access technologies, architectures, radio frequencies, with each combination termed as a "band" henceforth. Through comprehensive measurements in 12 cities across 5 countries, we experimentally show that operator-configured default bands are often highly sub-optimal, particularly under mobility. We then propose smart band switching, where UE's can be dynamically changed to improve the network performance boost application QoE. discuss...
Collaborative perception, which greatly enhances the sensing capability of connected and autonomous vehicles (CAVs) by incorporating data from external resources, also brings forth potential security risks. CAVs' driving decisions rely on remote untrusted data, making them susceptible to attacks carried out malicious participants in collaborative perception system. However, analysis countermeasures for such threats are absent. To understand impact vulnerability, we break ground proposing...
