Software Architecture-Based Adaptation for Pervasive Systems

Abstract: An important requirement for pervasive computing systems is the ability to adapt at runtime to handle varying resources, user mobility, changing user needs, and system faults. In this paper we describe an approach in which dynamic adaptation is supported by the use of software architectural models to monitor an application and guide dynamic changes to it. The use of externalized models permits one to make reconfiguration decisions based on a global perspective of the running system, apply analytic models to determine correct repair strategies, and gauge the effectiveness of repair through continuous system monitoring. We illustrate the application of this idea to pervasive computing systems, focusing on the need to adapt based on performance-related criteria and models.

Filter Similarities in Content-Based Publish/Subscribe Systems

Abstract: Matching notifications to subscriptions and routing notifications from producers to interested consumers are the main problems in large-scale publish/subscribe systems.Most previously proposed distributed notification services either use flooding or, if filtering is performed, they assume that each event broker has global knowledge about all active subscriptions. Both approaches degrade the scalability of notification services as the former wastes network resources and the latter generates overly large routing tables.In this paper we describe content-based routing algorithms that exploit filter similarities in order to reduce the size of routing tables and the number of control messages that are exchanged among the brokers in order to keep the routing tables up-to-date. In particular, the proposed algorithms do not assume global knowledge about all active subscriptions. Furthermore, we describe how these optimizations can be supported if the underlying data and filter model is based on structured records.

A Service-Oriented Architecture for Virtualizing Robots in Robot-as-a-Service Clouds

Abstract: Exposing software and hardware computing resources as services through a cloud is increasingly emerging in the recent years. This comes as a result of extending the service-oriented architecture (SOA) paradigm to virtualize computing resources. In this paper, we extend the paradigm of the SOA approach to virtualize robotic hardware and software resources to expose them as services through the Web. This allows non-technical users to access, interact and manipulate robots simply through a Web browser. The proposed RoboWeb system is based on a SOAP-based Web service middleware that binds robots computing resources as services and publish them to the end-users. We consider robots that operates with the Robotic Operating System (ROS), as it provides hardware abstraction that makes easier applications development. We describe the implementation of RoboWeb and demonstrate how researchers can use it to interact remotely with the robots. We believe that this work consistently contributes to enabling remote robotic labs using the cloud paradigm.

Runtime adaptation of applications through dynamic recomposition of components

Abstract: Software applications executing in highly dynamic environments are faced with the challenge of frequent and usually unpredictable changes in their execution environment. In order to cope with this challenge effectively, the applications need to adapt to these changes dynamically. CASA (Contract-based Adaptive Software Architecture) provides a framework for enabling dynamic adaptation of applications, in response to changes in their execution environment. One of the principle adaptation mechanisms employed in the CASA framework is dynamic recomposition of application components. In this paper, we discuss implementation issues related to the approach for dynamic recomposition of application components in CASA.

Deterministic execution model on COTS hardware

Abstract: In order to be able to use multicore COTS hardware in critical systems, we put forward a time-oriented execution model and provide a general framework for programming and analysing a multicore compliant with the execution model.
