Adaptive Channel Access Mechanism for Real Time Traffic over IEEE 802.11e Wi-Fi Network

The deployment of Wi-Fi network has been growing rapidly due to its ease of implementation and affordability in prize. The increase in number of users and applications results in increment of multimedia traffic in Wi-Fi networks. There are lots of performance issues in Wi-Fi network with respect to Quality of Services (QoS), especially with voice and video applications. In this paper we propose the adaptive channel access mechanism to improve the performance of real time traffic under high traffic environment. The proposed adaptive channel access mechanism improves the performance of voice and video traffic by 15% to 20% in terms of packet delay and throughput under high traffic load environment.
