Abstract
Different access network types are characterized by a variety of attributes which include link bandwidths, physical media, capacity, and reliability. Therefore, the question of accurately identifying whether the sender uses a wired ethernet connection or a wireless LAN connection comes into place. This article aims to analyse, simulate, validate, and improve the existing classification scheme which is based on measuring entropy of packet pair inter-arrival times and median. A riverbed modeller (former OPNET) is used for simulating the different scenarios. Small-scale experiment conducted on campus at the Nazarbayev University (NU) validates the insignificance of the packet probe size chosen for the classification.
