PIW: A QoS Provisioning Scheme for Efficient Real Time Data Transmission in Hybrid Wireless Networks

چکیده
The enhancement of QoS has emerged as a major research area in Real Time Multimedia Transmission in Hybrid Wireless networks. The network made up of Infrastructure and Adhoc Wireless Networks is sometimes referred to as Hybrid wireless network. We propose a scheme named PIW (PSNR Improvement in Wireless) to improve PSNR by using RTP/RTCP . RTCP provides control information that is used, by adjusting the compression rate, to achieve effiecient real time data transmission. Pre and Post analysis of network on NS-2 shows that significant improvement in overall efficiency and PSNR of hybrid wireless network is observed by using PIW.
