Code is here though: http://bobcopeland.com/srcs/wifi_sim.tar.gz Glancing at the wmediumd code again, it doesn't try to simulate airtime either, just does some loss reporting. Do you have a use-case which needs the airtime simulation? A while ago, I rewrote my PER computations in C instead of pre-generating them from matlab into a huge lookup table (see per.c): https://github.com/bcopeland/wmediumd/tree/add_per_model So, I'd be interested in hooking that up and throwing a scheduler into wmediumd to optionally simulate airtime. -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
