The interaction between wireless optimized scheduling algorithms and TCP congestion control mechanisms can have adverse effects on the performance of the system. We focus on the queue based max-weight (QBMW) scheduler, a scheduling strategy which is known to be throughput-optimal under unregulated traffic sources. We use fluid modeling to describe the time evolution of the congestion window size and...
Nowadays wireless wide area networks (e.g. cellular networks) are also used to provide access to Internet and its services. However, protocols and applications not specifically designed for wireless links (e.g., TCP, VoIP) often require a deeper analysis when applied to such links. Performance analysis represents a valid method to evaluate such protocols and applications, modeling their behavior and...
TCP has been shown to perform poorly in wireless environments in terms of throughput due to the inherent nature of wireless links. In this paper, we propose a Snoop-Based TCP Enhancements Scheme with Forced Duplicate Acknowledgement-(STE-FDA) over wireless cellular network, which combine both of Snoop-like TCP enhancements and the Forced Duplicate Acknowledgement (FDA) congestion control scheme at...
