Characteristics of Wireless LAN Traffic

I.W.C. Lee and A.O. Fapojuwo (Canada)


Wireless LAN, self-similarity, multifractals


Wireless LAN is a radio technology that allows users tether-less access to the network resources. In this paper we analyze three traffic traces collected at the data link layer from IEEE802.11b based campus wireless local area networks. The traffic traces are found to be self-similar and exhibit long range dependence property. Furthermore, we found that the traffic traces possess more intricate fractal structure, i.e., they are multifractal as well. This multifractal behaviour is found at small time scales as well as time scales of 10 seconds.
