Synchronizing clocks across computers over the Internet is an interesting problem. Much advancements has been made in this area due to the efforts of Mills et al. My research goal is to understand the usage of NTP and other clock synchronization protocols and also enhance the time synchronization of clocks over wireless links. I have developed frameworks that use the NTP data opportunistically, to understand one-way delay characteristics across the Internet [HotNets' 15]. In my current research, I'm working on improving time synchronization across a range of mobile and wireless devices, with an objective of developing protocols that improve accuracy without being resource intensive.
