A Safety Argument Strategy for PCA Closed-Loop Systems: A Preliminary Proposal

Authors: Lu Feng, Andrew L. King, Sanjian Chen, Anaheed Ayoub, Junkil Park, Nicola Bezzo, Oleg Sokolsky, and Insup Lee

Published in: OASIcs, Volume 36, 5th Workshop on Medical Cyber-Physical Systems (2014)

Abstract
The emerging network-enabled medical devices impose new challenges for the safety assurance of medical cyber-physical systems (MCPS). In this paper, we present a case study of building a high-level safety argument for a patient-controlled analgesia (PCA) closed-loop system, with the purpose of exploring potential methodologies for assuring the safety of MCPS.

Architecture-Driven Semantic Analysis of Embedded Systems (Dagstuhl Seminar 12272)

Authors: Peter Feiler, Jérôme Hugues, and Oleg Sokolsky

Published in: Dagstuhl Reports, Volume 2, Issue 7 (2013)

Abstract
Architectural modeling of complex embedded systems is gaining prominence in recent years, both in academia and in industry. An architectural model represents components in a distributed system as boxes with well-defined interfaces, connections between ports on component interfaces, and specifies component properties that can be used in analytical reasoning about the model. Models are hierarchically organized, so that each box can contain another system inside, with its own set of boxes and connections between them. The goal of Dagstuhl Seminar 12272 ``Architecture-Driven Semantic Analysis of Embedded Systems'' is to bring together researchers who are interested in defining precise semantics of an architecture description language and using it for building tools that generate analytical models from architectural ones, as well as generate code and configuration scripts for the system. This report documents the program and the outcomes of the presentations and working groups held during the seminar.

07011 Executive Summary – Runtime Verification

Authors: Bernd Finkbeiner, Klaus Havelund, Grigore Rosu, and Oleg Sokolsky

Published in: Dagstuhl Seminar Proceedings, Volume 7011, Runtime Verification (2008)

Abstract
From January 2 to January 6, 2007, the Dagstuhl Seminar 07011 "Runtime Verification" was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. Over the past few years, runtime verification has emerged as a focused subject in program analysis that bridges the gap between the complexity-haunted field of fully formal verification methods and the ad-hoc field of testing. Other terms for this subject are: program monitoring, dynamic program analysis, and runtime analysis. Thirty researchers participated in the seminar and discussed their recent work and recent trends in runtime verification.

Runtime Verification for Wireless Sensor Network Applications

Authors: Oleg Sokolsky, Usa Sammapun, John Regehr, and Insup Lee

Published in: Dagstuhl Seminar Proceedings, Volume 7011, Runtime Verification (2008)

Abstract
We present a case study that considers the application of runtime verification technology to a wireless sensor application. The case study is performed using the SURGE TinyOS application for multi-hop routing, which executes on the Avrora TinyOS simulator. We discuss the problems we have encountered in the course of case study. The problems include unclear correctness properties for wireless network applications (indicating ad hoc development process) and inadequate tool support. A wireless sensor network usually comprises of a collection of tiny devices with built-in processors that can gather physical and environment information such as temperature, light, sound, etc., and communicate with one another over radio. Many wireless sensor network applications sit on top of an operating system called TinyOS and are mostly written in nesC, an extension of C that provides a component-based programming paradigm. Most of wireless sensor network applications are developed and tested on a simulator before they are deployed in the environment because testing and debugging directly on physical devices are very difficult, especially when the network consists of many nodes, and may not provide enough information for debugging. A simulator usually produces detailed execution information and can help find errors. However, even with the simulator and nesC, the current state of development tools for wireless sensor network still requires very low-level programming, which makes it hard for the developers to maintain a high-level view of the system operation. During the validation stage, lack of sophisticated debugging tools for sensor networks makes it difficult to make the connection between a high-level functional or performance requirement and a particular aspect of system implementation. This paper investigates a high-level approach to examine execution data from a simulator and analyze it using runtime verification. The technique 1) identifies and formally specifies high-level requirements for the system under development, 2) monitors a distributed wireless sensor network application using data provided by the simulator, and 3) checks for timing and dynamic properties to gain understanding of the relevant behaviors of wireless sensor nodes and to provide a systematic approach in finding bugs and errors. A particular runtime verification used inthis paper is MaC. MaC provides specification languages capable of expressing functional, timing, and probabilistic properties to specify requirements or patterns of errors. Properties can, for example, examine periodic behaviors or identify a faulty node. MaC then monitors and checks a wireless sensor network application against its specification by observing data produced by a simulator. The motivation for applying the monitoring and checking technique to check wireless sensor network applications is threefold: 1) raise the development level for wireless sensor network, 2) provide a mechanism for understanding high-level behaviors of the system in terms of low-level observation, and 3) provide a tool based on the acceptance of the state of the art development tool for sensor networks.

06161 Working Groups' Report: The Challlenge of Combining Simulation and Verification

Authors: Gregory Batt, Jeremy T. Bradley, Roland Ewald, François Fages, Holger Hermans, Jane Hillston, Peter Kemper, Alke Martens, Pieter Mosterman, Flemming Nielson, Oleg Sokolsky, and Adelinde M. Uhrmacher

Published in: Dagstuhl Seminar Proceedings, Volume 6161, Simulation and Verification of Dynamic Systems (2006)

Abstract
Simulation has found widespread use for experimentation and exploration of the possible impacts of a variety of conditions on a system. In contrast, formal verification is concerned with proving or disproving the correctness of a system with respect to a certain property, using mathematical and logical methods.
