We present performance evaluation results of a QoS supporting ad hoc network protocol which employs a hybrid approach utilizing both TDMA and 802.11 DCF. In the protocol, TDMA period provides contention free transmissions for QoS flows, and DCF period is used to provide contention-based access for best effort or low priority flows. TDMA time slots are assigned on admission basis in a distributed manner by utilizing network routing information and considering current assignment situation. In DCF period, frames are transmitted without disturbing the TDMA period. We evaluate the protocol for various numbers of best effort flows with QualNet simulator. Simulation results show that the protocol is able to provide an efficient solution for QoS control in ad hoc networks by combing TDMA and 802.11 DCF. |
