Performance measurements of 802.11 WLANs with burst background traffic

With the large diffusion of wireless communication industrial environments will soon be involved, including those applications where granting limited response times is of utmost importance. Delays are important issues for soft real-time applications and this paper analyzes the impact of a burst traffic on the performance of real 802.11g and 802.11e networks. In particular, how some stations that generate burst traffic, for example alarm storms, can create problems on a communication on the same priority class (802.11g) or on an higher priority class (voice over 802.11e). An analysis on this topic and some measurements are presented.
