On the 802.11 Turbulence of Nintendo DS and Sony PSP Hand-held Network Games is a paper by Mark Claypool that analyses the traffic characteristics of IEEE 802.11 network games on the Nintendo DS and the Sony PSP. Here is the questions they try to answer:

What is the network turbulence for hand-held network games?

Does the network turbulence for different hand-helds (such as the PSP and the DS) differ from each other?

Does the network turbulence for different games (such as Ridge Racer and Super Mario on the same handheld differ from each other?

Does the network turbulence for hand-held games differ from PC games?

Does hand-held game traffic interfere with traditional Internet traffic on the same wireless channel?

Why do I blog this? the paper is quite technical so it's less my focus but the question they ask are interesting from the user experience point of view. This might be close to Fabien's research. How people cope with those turbulences? are there any compensations or strategies (in-game) to handle them?
