The Discontinuous Reception (DRX) is the most effective timer-based mechanism for User
Equipment (UE) power saving. In Long Term Evolution (LTE) systems, the development of …

Mobile edge computing (MEC), as a key ingredient of the 5G ecosystem, is envisioned to
support demanding applications with stringent latency requirements. The basic idea is to …

Edge computing responds to users' requests with low latency by storing the relevant files at
the network edge. Various data deduplication technologies are currently employed at edge …

With the development of communications, various applications of communication
technologies, such as remote driving, delivery drones, and telesurgery, are emerging. In …

In this paper, we devise new attacks exploiting the unprotected data-plane signaling in
cellular IoT networks (aka both NB-IoT and Cat-M). We show that, despite the deployed …

This paper reports our five-year lessons of developing and using MobileInsight, an open-
source community tool to enable software-defined full-stack, runtime mobile network …

As a novel UDP-based transport protocol which supports stream multiplexing, QUIC is faster,
more lightweight and flexible than TCP. With the prevalence of multi-homed devices such as …

Vehicle-to-everything (V2X) networks will constitute a prominent application in future
generations of cellular networks, definitely transforming our conception of transportation …

We devise new attacks exploiting the unprotected data-plane signaling in cellular IoT
networks (aka both NB-IoT and Cat-M). We show that, despite the deployed security …

While 5G has rolled out since 2019 and exhibited versatile advantages, its performance
under high/extreme mobility scenes (eg, driving, high-speed railway or HSR) remains …
