Worst-Case Traffic in a Tree Network of ATM Multiplexers (2008)
José M. Barceló, Jorge García-vidal, Olga Casals
Abstract—In this paper we study tree networks of discrete-time queues loaded with periodic traffic sources. By using the so-called Beneˇs method, exact closed-form expressions are obtained for the...
Portable microsensors based on individual SnO2 nanowires (2007)
Hernández-Ramírez, Francisco, Prades, J. D., Tarancon, A, Barth, Sven, Casals, Olga, Jimenez-Diaz, R, ...
Individual SnO2 nanowires were integrated in suspended micromembrane-based bottom-up devices. Electrical contacts between the nanowires and the electrodes were achieved with the help of electron- and...
1 A Per-VC Global FIFO Scheduling Algorithm for Implementing the New ATM (2007)
Gfr Service, O Cerdan, Olga Casals
The performance of various GFR (Guaranteed Frame Rate) implementations has been recently studied due to the interest to provide bandwidth guarantees with a simpler implementation than ABR in ATM...
Study of the TCP Unfairness in a Wireless Environment 1 (2007)
In this paper we analyze the TCP performance degradation introduced by a wireless media having transmission errors and the capability of the following mechanisms to correct it (i) improvements over...
CDVT Dimensioning in the ABR Service of ATM Networks (2007)
The Available Bit Rate Service (ABR) has been designed to be an efficient data transport Service for ATM networks. The standardization bodies have defined the Dynamic Generic Cell Rate Algorithm...

Blondia, Chris, Van Den Wijngaert, Nik, Willems, Gert, Casals, Olga, Cerda, Llorenc, Bagnulo Braun, Marcelo, ...
We point out the different performance problems that need to be addressed when considering mobility in IP networks. We also define the reference architecture and present a framework to classify the...
Fabio Vena, Lloren Cerdà, Olga Casals
Several IP micro-mobility protocols have been proposed to enhance the performance of Mobile IP in an environment with frequent handoffs. In this paper we make a detailed study of how two of these...
Implementation Issues to Provide the GFR Service Guarantees to TCP/IP Traffic (1998)
The performance of various GFR (Guaranteed Frame Rate) implementations has been recently studied due to the interest to provide bandwidth guarantees with a simpler implementation than ABR in ATM...
