Abstract :
The paper presents a multi-cell dynamic reservation (MCDR) protocol to support voice with CBR, video with VBR and data with ABR over IEEE 802.11 Ad hoc wireless LAN. The quality of real-time service (voice and video) can be guaranteed by reserving cell. Moreover, MCDR defines multi-cell respectively for CBR and VBR real-time services to meet their different requirement on QoS. A suitable analytical approach is proposed in order to evaluate the performance of real-time traffic. Simulations show that MCDR is able to provide almost 90% channel utilization, low packet loss due to delay exceeded, and low jitter for voice.
