Dwell adaptive fragmentation: how to cope with short dwells required by multimedia wireless LANs

This paper studies the impact on CSMA/CA traffic of a reduction of the dwell size, a fundamental parameter of some wireless LANs. First, we explain why we want to reduce the dwell size and what are the consequences. Then, we present some ways to overcome the overhead of short dwell, mostly based on fragmentation. We finish by some exhaustive simulations of the short dwell size impact and variations, and the way those fragmentation schemes improve the network performance.
