Main research findings

 

  • The Internet has become an absolutely critical part of our infrastructure. We rely on it for everyday tasks. Paying for things. Entertainment. Talking to friends and family. Many simple things become difficult, annoying, or even impossible when our internet connection lets us down. To many people, “WiFi” is synonymous with “Internet.” It’s how we usually connect when at home or at work. But WiFi can not be trusted. It often lets us down. When we are doing something interactive, like talking to someone on video or playing an online game, a bad WiFi connection can be very frustrating. In this thesis, we study why WiFi is unreliable, measure how big this problem really is, and explore how it can be solved.
