Congestion control and user utility function for real-time traffic

Usage of multimedia communication in everyday life has seen a remarkable growth. Vast in Bandwidth demand often result in lower network performance and reduced quality of user experience during congestion. In this paper, we will address congestion control problem while providing quality of service (QOS) of delay for inelastic flows like video streaming, IPTV, etc. First, we propose an extension of an existing user utility function to capture user's satisfaction over bandwidth allocation, QoS, and the cost to acquire the service. Second, we will study the relationship between these three entities.
