Lessons from Four Years of PHONELAB Experimentation [article]

Jinghao Shi, Edwin Santos, Geoffrey Challen
2019 arXiv   pre-print
Over the last four years we have operated a public smartphone platform testbed called PHONELAB.  ...  PHONELAB consists of up to several-hundred participants who run an experimental platform image on their primary smartphone.  ...  For the past four years we have operated a public smartphone platform testbed called PHONELAB. PHONELAB allows researchers to deploy platform modifications to between 100 and 300 participants.  ...

Race to improve student understanding of uncertainty: Using LEGO race cars in the physics lab

Maria Parappilly, Christopher Hassam, Richard J. Woodman
2018 American Journal of Physics  
One very clear lesson from the present study was that in any multi-year investigation the same teaching team, in particular the lab demonstrators, should be retained.  ...  Four series of practical sessions were run in the initial semester, each with a different demonstrator from that pool.  ...

We end with a description of the current LiveLabs status (> 700 active participants to date) as well as present some key lessons learned.  ...  The key goal of LiveLabs is to allow insitu real-time experimentation of mobile applications and services that require context-specific triggers with real participants on their actual smart phones.  ...  an experimentation service that frees experimenters from many experimental chores (such as subject selection, privacy enforcement etc.).  ...

Evaluating reliable streaming in mobile networks

Florian Metzger
2014 unpublished
Additionally, video streaming has changed radically changed in recent years, shifting from traditional approaches running atop the unreliable UDP to using the reliable TCP as transport protocol.  ...  Concerning mobile networks, a network trace from a live network is evaluated and explored for characteristics of the core network control plane.  ...  And these are also the lessons learned during the course of this thesis's work.  ...
