Abstract: This paper proposes a new multiple access control (MAC) protocol named distributed synchronous reservation multiple
access control protocol(DSRP), in which the hidden and exposed terminal problems are solved, and the QoS(Quality of Service)
requirements for real-time traffic are ensured. The protocol is based on Time Division Multiplex Address(TMDA) and a
different type of traffic is assigned to different priority, according to which a node should compete for and reserve the
free slots in a different method. Moreover, there is a reservation acknowledgement process before the data transmitting in
each reserved slot, so that the intruded terminal problem is solved. The throughput and packets average drop probability of
this protocol are analyzed and simulated in a fully connected network, the results of which indicate that this protocol is
efficient to supporting real-time traffic and more suitable to MANETs.

Key words: real-time traffic, multiple access control(MAC), packet reservation multiple access, mobile Ad Hoc networks
