A Scheme for Fairness Modification of the DBTMA Protocol
Lihua Zhang · Journal of Hohai University Changzhou · 2007
In Ad Hoc networks,the operation of Dual Busy Tone Multiple Access(DBTMA) solves the hidden and the exposed-terminal problems,but it causes the fairness problem at which some modification has been proposed aimed.In improved DBTMA,the transmit busy tone is got rid of and the RTS packet is transmitted in slotted ALOHA scheme,which improves the probability of successful RTS reception.The result of simulation shows that improved DBTMA scheme decreases the complexity of the protocol,reduces the transmission delay,and guarantees the fairness of system and the steady performance.
