ABSTRACT

Mobile ad hoc networks (MANETs) are useful in environment where fixed network infrastructure is unavailable. MANETs demand an efficient and distributed Medium Access Control (MAC) protocol to effectively reduce collisions and thus becomes a key issue for MAC design in MANETs. Several mechanisms have been proposed to avoid collisions, achieve fairness with the help of carrier sensing, handshaking, and back-off mechanism. The use of multiple channels in wireless networks could provide performance advantages in reducing collisions and enabling more concurrent transmissions. This paper provides a brief study on two popular Contention based MAC protocol - BTMA and DBTMA.
