Investigating channel bonding and TXOP in 802.11n wireless networks

This paper provides a brief investigation of 802.11n based channel bonding protocol. The aim is to expose the protocol as a flow chart diagram and show how the increase in TXOP interval length affects overall channel utilization. In addition we investigate fairness of the protocol and demonstrate that the protocol is relatively unfair in respect to providing the same level of access to transmission opportunity to all neighboring access points. Furthermore we show that the fairness significantly decreases with the number of neighboring access points and only slightly decreases with an increase in TXOP length.
