Abstract

The popularity of CSMA/CA based wireless networks such as IEEE 802.11 standards has resulted in deployment of many wireless network zones in various areas such as residences and public spaces. To analyze and improve the performance of these wireless networks, many researchers recently have adopted methods from stochastic geometry theory. However, for more realistic analysis of wireless networks, we think elastic Internet flows such as TCP traffic need to be considered along with stochastic geometry setups. In this paper, we use Poisson point process to model the geographic distribution of IEEE 802.11a access points in given areas and evaluate TCP performance in various scenarios such as different AP densities and MCS levels through simulations.

Footnotes
1
Existing IEEE 802.11Ext modules use designated MCS levels when decoding received packets. But only MCS level 0 is used when packets are sent.
 
2
Note that, in MCS level 3 and low density cases, some users do not achieve any throughput since they are too far from their closest APs.
