DESCRIPTION:Abstract:\nWireless networks are becoming ever more sophistica
 ted and overcrowded\, imposing the most delay\, jitter\, and throughput da
 mage to end-to-end network flows in today’s internet. We therefore\, arg
 ue for fine-grained mobile endpoint-based wireless measurements to inform 
 a precise congestion control algorithm through a well-defined API to the m
 obile’s wireless physical layer. Our proposed congestion control algorit
 hm is based on physical-layer bandwidth measurements taken at the endpoint
 \, and captures the latest 5G New Radio innovations that increase wireless
  capacity\, yet create abrupt rises and falls in available wireless capaci
 ty that the sender can react to precisely and very rapidly. We implement a
  proof-of-concept prototype of the measurement module on software-defined 
 radios and the sender and receiver in C. An extensive performance evaluati
 on compares our system head to head against the leading wireless-aware and
  wireless-oblivious congestion control protocols proposed in the research 
 community and in deployment\, in mobile and static mobile scenarios\, and 
 over busy and quiet networks. Results show 6.3% higher average throughput 
 than BBR\, while simultaneously reducing the 95th percentile delay by a fa
 ctor of 1.8×.\n \nBio:\nKyle Jamieson is an Associate Professor in the De
 partment of Computer Science at Princeton University and Honorary Reader a
 t University College London.  His research focuses on building mobile and 
 wireless systems for sensing\, localization\, and communication that cut a
 cross the boundaries of digital communications and networking.  He receive
 d the B.S. (Mathematics\, Computer Science)\, M.Eng. (Computer Science and
  Engineering)\, and Ph.D. (Computer Science\, 2008) degrees in Computer Sc
 ience from the Massachusetts Institute of Technology.  He then received a 
 Starting Investigator fellowship from the European Research Council\, a Go
 ogle Faculty Research Award\, and the ACM SIGMOBILE Early Career Award.\n\
