ALZATE, Marco A.; MEJIA, Marcela; PENA, Néstor M.  and  LABRADOR, Miguel A.. Achievable transmission rate in an IEEE 802.11 Manet link. Rev.fac.ing.univ. Antioquia [online]. 2012, n.62, pp.126-136. ISSN 0120-6230.

For management purposes, it is very important to estimate the available bandwidth for each link in a MANET, in an accurate, timely and efficient way. In this paper we show analytical results on the probability distribution function of the bandwidth of a link in a MANET based on IEEE 802.11, that take into account transmission errors. We also show some analytical results on the fraction of time the channel is available for a given virtual link, so the effects of other transmitting nodes can also be taken into account. Together, these results can be usefully exploited in an efficient, accurate and distributed available bandwidth estimation mechanism.

Keywords : MANET; IEEE 802.11; bandwidth; RTS/CTS; packet length dependency; busy period.
