Applied Computing has been a primary gathering forum for applied computer scientists, computer engineers, software engineers, and application developers from around the world. SAC 2008 is sponsored by the ACM Special Interest Group on Applied Computing and is hosted by the University of Fortaleza and the Federal University of Ceara.

Track Overview

Distributed systems, services and databases are at the core of the information society and increasingly pervade many aspects of our daily lives. While mobility and pervasiveness require support for systems that adapt themselves to changing environments, resources, and user needs, the middleware infrastructures become more and more heterogeneous and complex. This trend is further fueled by the emergence of service oriented computing. In addition, we can see an increasing demand for dependability and security of such systems, taking into account the software as well as the surrounding environment. This mismatch between increasing demand for dependability on one hand and a degradation of dependability caused by complexity, scale, and dynamics has recently been termed by Laprie as the "dependability gap".

Generally, adaptiveness can either satisfy a change in user requirements or seek to fulfill the same requirements in a changing system context and environment. In particular, adaptation is also a means to achieve dependability in a computing infrastructure with dynamically varying structure and properties. Dependability and adaptiveness are cross-cutting concerns, driven by architectural decisions, design, and flexibility. Therefore, the focus of this track is on middleware support for dependability and adaptiveness of distributed software systems and service environments of any kind and on methods on designing and engineering them.

This is the third year for the DADS track and 36 submitted papers show the importance of the topic. 31 reviewers performed our double-blind review process, where each paper has been reviewed by three reviewers. Finally, ten regular papers have been accepted resulting in an acceptance rate of 28%. Three more submissions have been accepted as poster papers.


The DADS track provides a forum for scientists and engineers in academia and industry for their latest research findings on selected topics in dependable and adaptive distributed systems and complex service infrastructures. The track is structured in two sessions:

Session DADS-1: Wednesday, March 19, 2008, 10:30-12:10

The first session focuses on the dependability and security properties of complex systems and how these properties can be maintained and balanced in an adaptive way. In particular, the following papers comprise this session:
  1. Performability Evaluation of Mobile Client-Server Systems
    (O. Das and A. Das)
  2. A framework for dependable QoS adaptation in probabilistic environments
    (A. Casimiro, P. Lollini, M. Dixit, A. Bondavalli, and P. Verissimo)
  3. Improving Denial of Service Resistance using Dynamic Local Adaptations
    (G. Badishi and I. Keidar)
  4. Serpentine: Adaptive Middleware for Complex Heterogeneous Distributed Systems
    (M. Matos, A. Correia Jr., J. Pereira, and R. Oliveira)
  5. Providing Dependability for Web Services
    (J.L.R. Souza and F. Siqueira)

Session DADS-2: Wednesday, March 19, 2008, 13:30-15:10

The second session focuses first on questions regarding replication and ordering guarantees in group communication as underlying technologies for dependable systems. Second, this session focuses on the questions of modeling and adaptivity. In detail, the following papers are part of this session:
  1. Conflict-Aware Load-Balancing Techniques for Database Replication
    (V. Zuikeviciute and F. Pedone)
  2. SIPRe: A Partial Database Replication Protocol with SI Replicas
    (J.E. Armendariz-Inigo, A. Mauch-Goya, J.R. Gonzalez de Mendivil, and F.D. Munyoz-Escoi)
  3. Total Order Broadcast on Pervasive Systems
    (L.A. Steffenel, M. Kirsch Pinheiro, and Y. Bebers)
  4. Model-Driven Development of Component-based Adaptive Distributed Applications
    (A. Phung-Khac, A. Beugnard, J.-M. Gilliot, and M.-T. Segarra)
  5. Modelling Adaptive Services for Distributed Systems
    (L. Rosa, A. Lopes, and L. Rodrigues)

Poster sessions: Tuesday, March 18, 2008

Finally, three poster papers have been accepted:
  1. SSCM: Middleware for Structure-based Service Collaboration
    (D. Ma, M. Liu, Y. Zhao, and C. Hu)
  2. On the Control of Adaptation in Ubiquitous Computing Systems
    (L.C. da Silva, C.A. da Costa, C. Geyer, I. Augustin, and A.C. Yamin)
  3. A Pattern-Driven Security Process for SOA Applications
    (N.A. Delessy and E.B. Fernandez)
