How to reduce congestion on TCP/AQM networks with simple adaptive PID controllers
Teresa Álvarez, Anuar Salim · 2012
Congestion is a problem in real networks. Users do not want to lose information and data should be delivered as fast and reliably as possible. This is really difficult to achieve. Moreover, networks work in changing environments: number of users, type of traffic, delays in transmission, etc. So this paper presents how to design PID controllers that take network changes into account. Non-linear simulations using ns-2 will show the goodness of the approach when compared with classical PID, drop tail and RED.
