Abstract
This paper focuses on how to differentiate wireless traffic from wired peer by using the temporal TCP characteristics of SYN, FIN, and ACK local round trip times (LRTT) found in all TCP sessions. With these session-based temporal characteristics, traffic from wireless and wired nodes can be differentiated by exploiting the fundamental differences between Ethernet and 802.11b/g/n. The effort of this paper is then on analyzing the resulting empirical LRTT data extensively and designing several algorithms for effective wireless host discovery. Most algorithms are light-weight, with little memory overhead, and can be easily implemented on commodity hardware. Ultimately, SYN, FIN, and ACK LRTTs can be compared against each other to discover wireless hosts regardless of network speeds.
