Sliding mode-like congestion control for communication networks with heterogeneous applications

This paper develops a fair and efficient congestion control framework using robust sliding mode control. It not only considers the limitations of current optimal congestion control approach, but also guarantees the performance of heterogeneous applications with different Quality of Service (QoS) requirements. By further proposing enhanced sliding mode-like congestion control algorithms, the paper addresses two critical issues raised from previous work [1], namely, the rigorous stability of the system and the sensitivity of design parameter. The thorough treatment makes the framework practically applicable, as well as retains its appealing properties. Moreover, the paper summarizes the applications of sliding mode approach in communication networks and highlights its great potential ahead.
