Applied Computing has been a primary gathering forum for applied computer scientists, computer engineers, software engineers, and application developers from around the world. SAC 2009 is sponsored by the ACM Special Interest Group on Applied Computing and is hosted by the University of Hawaii at Manoa and the Chaminade University of Honolulu.

Track Overview

Dependability is no longer restricted to critical applications, but rather becomes a cornerstone of the information society. Dependability clearly is a holistic concept: Contributing factors are not only technical, but also social, cultural (i.e. corporate culture), psychological (perceived dependability), managerial (information management and processes), and economical. Fostering learning is a key, and simplicity is generally an enabler for dependability.

Unfortunately, heterogeneous, large-scale, and dynamic software systems that typically run continuously often tend to become inert, brittle, and vulnerable after a while. The key problem is, that the most innovative mobile and pervasive systems and applications are the ones that also suffer most from a significant decrease in (deterministic) dependability when compared to traditional critical systems, where dependability and security are fairly well understood as complementary concepts and a variety of proven methods and techniques is available today. In accordance with Laprie we call this effect the dependability gap, which is widened in front of us between demand and supply of dependability, and we can see this trend further fueled by an ever increasing cost pressure.

Future systems need to close the dependability gap in face of challenges such as cross-organisational heterogeneity, massive scale, and mobility. Of course, dependability and adaptiveness can not simply be added to a system like a plug-in module. Rather, for databases, services, middleware, and software development, application developers need tools, sound methodologies, common practices, standards, architectural principles, and middleware services, to tackle the inherent complexity and emerging behavior of distributed systems and to ensure trustworthy services. Therefore, the vision of this track is on the convergence of software development tools with middleware, traditional dependability, fault tolerance, security, and adaptivity concepts, together with social and psychological aspects, to compensate for dependability degradation of running software and services.


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. The track is structured in two sessions:

Session DADS-1: Tuesday March 10, 2009, 8:20–10:00

The first session focuses on the adaptivity, dependability, and security properties of complex systems. In particular, the following papers comprise this session:

  1. A Framework for Dynamic Adaptation of Power-Aware Server Clusters
    (Vinicius Petrucci, Orlando Loques, and Daniel Mossé)
  2. Adaptive Resource Management Architecture for Distributed Real-Time Embedded Systems
    (Ke Liang, Xingshe Zhou, Ruiqing Sheng, and Kailong Zhang)
  3. Formalizing the Notion of Adaptive System Behavior
    (Manfred Broy, Christian Leuxner, Wassiou Sitou, Bernd Spanfelner, and Sebastian Winter)
  4. ATM: An Automatic Trust Monitoring Algorithm for Service Software
    (Mohammad Uddin and Mohammad Zulkernine)
  5. Supporting Recovery, Privacy and Security in RFID Systems Using a Robust Authentication Protocol
    (Md. Endadul Hoque, Farzana Rahman, and Sheikh Ahamed)

Session DADS-2: Tuesday March 10, 2009, 10:30–12:10

The second session focuses on performance, quality of service, and optimization of dependable and adaptive systems. In detail, the following papers are part of this session:

  1. Adaptive Optimal Checkpoint Interval and Its Impact on System's Overall Quality in Soft Real-Time Applications
    (Nianen Chen and Shangping Ren)
  2. Latency-Aware Leader Election
    (Nuno Santos, Martin Hutle, and André Schiper)
  3. Boosting the Performance of Computing Systems through Adaptive Configuration Tuning
    (Haifeng Chen, Guofei Jiang, Hui Zhang, and Kenji Yoshihira)
  4. Efficient Maintenance of Distributed Data in Highly Dynamic Opportunistic Grids
    (Raphael de Camargo, Fernando Castor Filho, and Fabio Kon)
  5. Dynamic Planning and Weaving of Dependability Concerns for Self-Adaptive Ubiquitous Services
    (Romain Rouvoy, Frank Eliassen, and Mikaël Beauvois)

Poster session

Finally, a poster paper has been accepted:

  1. An Approach to Identifying Conversation Dependency in Service Oriented System during Dynamic Evolution
    (Min Liu, Dianfu Ma, and Yongwang Zhao)
