Making WiFi sharing a new social practice: PERM
-
-
Definitively, Spain is the place to live if you want to be a arch-expert on WiFi bandwidth sharing. Not only the country is the cradle of Fon and its “free” network. But now, the same country is where Haiyun Luo and his group of grad students decided to unveil the PERM, a software that is supposed to improve the WiFi quality of sharing while protecting networks more efficiently.
PERM is short for Practical End-host collaborative Residential Multihoming. It automatically analyzes users’ networking behaviors, and exploits the identified patterns to achieve high-performance scheduling at the flow level.
For instance, it distributes a very tiny portion of your bandwidth if you are already stuck in a voice conference call, and shares a broader portion if you’re just downloading emails.
The software can also recognize users and eventually block unwanted unwanted ones. According to Mr. Haiyun, who has been discussing it with ISP for two years, the blocking feature could be a valuable reason to authorize router owners to share their bandwidth.
The software is a grad student project of the University of Illinois at Urbana-Champaign (UIUC) and is released under an open source license. You can grab it here.
