Abstract CSMA/CA protocols rely on the random deferment of packet transmissions. Like most other protocols, CSMA/CA was designed with the assumption that the nodes would play by the rules and control the deferment themselves. However, with the higher programmability of the network adapters, the temptation to tamper with the software or firmware is likely to grow. The key point is to find the most appropriate and efficient way, in which a user could obtain a much larger share of the available bandwidth at the expense of other users. Various authors have proposed different techniques for improving the fairness and performance of CSMA/CA. This paper shows the comparative study of various proposed methodologies.
