  ABSTRACT: This paper describes a method for finding the stability regions of the PI and PIP controllers for TCP AQM with delays. The method is applied on several representative examples, showing that stable controllers can exhibit widely different performance. Thus, the results highlight the importance of optimizing the design of PI AQM. Furthermore, the paper shows that the previously proposed PIP controller can be unstable in the presence of delays even for the control parameters given in the literature.

  Article: Transversal issues in real-time sense-and-respond systems

  [show abstract] [hide abstract]
  ABSTRACT: Networked S&R systems extend human capabilities be-yond temporal and spatial barriers with useful applica-tions in broad areas. Involving the physical-world en-vironments, S&R systems must fulfill the intrinsic real-time requirements of these physical environments. How-ever, communication networks lack of QoS can hamper performance and effectiveness of S&R. Therefore, end system strategies must be deployed to retain effective-ness and to enhance performance of S&R. In this paper, we survey transversal issues pertaining to the develop-ment of agile S&R systems to work over a geographi-cally scalable network.
