Characterization of idle periods in IEEE 802.11e networks
Jelena Mišić, Vojislav B. Mišić · 2011
In this paper we investigate probability distribution of idle time in IEEE 802.11e networks with an access point. The probability distribution is shown to be sub-geometric and it can be approximated with a sub-exponential Gamma distribution. Secondary network operating within the transmission range of such a WLAN can use these probability distributions to estimate the probability of collisions with the transmissions from WLAN nodes, and make decision about the timing of their own forthcoming transmissions.
