MAC protocols for multimedia traffic transmission in mobile ad hoc networks have been studied steadily. It is still challenging to design an efficient protocol due to limited resource and multi-hop transmission property. CSMA-based MAC protocol is not suitable for multimedia traffic transmission due to hop-by-hop contention and collision. TDMA-based MAC protocol is appropriate to transmit time-sensitive traffic but slot allocation and sharing of slot information mechanism is essential. In this paper, the authors propose a novel TDMA MAC protocol for mobile ad hoc networks, which includes distributed resource reservation and resource state sharing mechanism.
