Active queue management for TCP-governed wireless networks
Vishwesh Kulkami, Myungsoo Jun, Peter Falb · 2003
A theoretical framework is proposed to analyze the performance of active queue management (AQM) protocols in TCP-governed wireless networks. It is assumed that the TCP-governed sources operate in the linear-increase-multiplicative-decrease mode. A bottleneck network topology involving a single router and multiple users is examined and it is shown that the problem of synthesizing stabilizing AQM controllers is equivalent to that of solving a class of bilinear matrix inequality (BMI) problems. A series of such BMI formulations for a class of AQM controllers is presented and it is observed that some of these formulations can be recast as linear matrix inequality (LMI) formulations, which can be solved efficiently.
