Performance Analysis of IEEE 802.11 DCF and IEEE 802.11e EDCF Under Same Type of Traffic
Mobile ad hoc network is adaptive computing and self-configuring network that automatically form their own infrastructure without support of any base station. The IEEE standard 802.11 protocol is generally used for wireless LAN. This standard 802.11 specifies DCF mode of Mac protocol that does not support quality of service (QoS) as all stations have same priority. To develop the basic performance in real-time application such as video and audio, QOS is essential. So, the standard 802.11e specifies EDCF mode of Mac protocol that enhances the DCF to provide prioritized QOS. Most of the performance of this protocol have evaluated for ideal environment. In this paper, the performance of Mac protocol is evaluated through simulation by using QUALNET software without assigning any priority for non-ideal environment by using performance matrix such as throughput, delay, and jitter.
