This directory contains the data and sample code used in the paper:
Towards Peer-Assisted Rendering in Networked Virtual Environments Minhui Zhu, Sebastien Mondet, Géraldine Morin, Wei Tsang Ooi, and Wei Cheng, In Proceedings of the 19th ACM International Conference on Multimedia (MM'11), Scottsdale, AZ, 28 November - 1 December 2011, 183-192.
The data consists of Second Life mobility traces [1] collected from four regions over different days.
The sample code consists of two scripts: one to compute visual similarity amongs the avatars, the other is to bin the similarities to count the number of peers with similiarity larger than a treshold.
