The configuration of WLAN MAC by means of super frame (SF) and contention free period (CFP) variation is one of the effective schemes to provide appropriate QoS to interactive multimedia (IMM) traffic. In this paper we investigate the usefulness of a dynamic auto-generated parameter set of CFP and SF combinations as the logical look-up table for the WLAN medium access control scheme. A modified analytical...
In this paper, a robust FGS video transmission scheme is proposed for streaming video over bandwidth-constrained packet loss channel, which aims to reducing both the overall distortion and quality fluctuation at the same time. We first use channel budget and packet loss property to determine the bits of enhancement layers that should be allocated per frame. Then unequal loss protection (ULP) using...
We designed and built a novel all-optical re-timing, re-amplifying, and re-shaping (3R) regeneration system based on terahertz optical asymmetric demultiplexers (TOADs) developed in our laboratory. The system is capable of parallel processing multiple wavelengths, a feature which will significantly improve the scalability of current wavelength division multiplexing (WDM) networks. Performance against...
