Weighted Fair Queuing in Wireless Networks
Abstract: Due to the rapid growth of wireless data services, the issues of providing different quality of services and fair channel access have become more and more crucial. In wireless networks, there are many mature fair queuing algorithms that can provide fairness and bounded delay properties. However, they cannot be directly applied to wireless networks because of the bursty and location-dependent error characteristics of wireless channels. So many fair queuing algorithms …

OFDM Technique for Efficient Image Transmission over Fading Channels for Different Modulation Schemes
Abstract: We propose an OFDM coding scheme for image transmission over wireless fading channels in this paper. OFDM is a digital data modulation technique that splits a single data stream into numerous sub-streams for transmission over multiple channels. We examine the MSE vs SNR of OFDM signals in multipath slowly fading channels in detail. The proposed system uses a rate control algorithm for image coding and an adaptive modulation OFDM system …
