End-to-End Delay Guarantee for TDMA-Based Ad Hoc Networks with RT-DSR Protocol

The hard real time guarantee in the Ad hoc networks seems to be a difficult task due to the features of such networks. For that reason, it is not sufficient to propose a routing protocol which guarantees the hard real time transfer. We are also interested in the medium access method. In this paper, after describing our routing protocol RT-DSR (Real-Time DSR), we present the TDMA (Time Division Multiple Access) access methods for the Ad hoc networks and we propose a TDMA approach which can offers better delay guarantees. The simulation results performed with NS2 simulator show that our protocol RT-DSR offers better delay values than the DSR routing protocol and prove that the TDMA access method is more suitable than the 802.11 access method.
