  We show a way to evaluate functional properties of distributed algorithms by the example of the AODV algorithm in sensor networks, Creol and ABS models, and component testing. We present a new method to structure the evaluation work into the categories of techniques, perspectives, arrangements, and properties using executable models. We demonstrate how to use this structure for network simulations and component testing using Creol models and demonstrate how the delta modelling technique of the ABS language can be used to facilitate the approach.

  We extend and implement a modeling language based on concurrent active objects with application-level scheduling policies. The language allows a programmer to assign priorities at the application level, for example, to method definitions and method invocations, and assign corresponding policies to the individual active objects for scheduling the messages. Thus, we leverage scheduling and performance related issues, which are becoming increasingly important in multi-core and cloud applications, from the underlying operating system to the application level. We describe a tool-set to transform models of active objects extended with application-level scheduling policies into Java. This tool-set allows a direct use of Java class libraries; thus, we obtain a full-fledged programming language based on active objects which allows for high-level control of deployment related issues.

  Modern software systems must support a high degree of variability to accommodate a wide range of requirements and operating conditions. This paper introduces the Abstract Behavioural Specification (ABS) language and tool suite, a comprehensive platform for developing and analysing highly adaptable distributed concurrent software systems. The ABS language has a hybrid functional and object- oriented core, and comes with extensions that support the development of systems that are adaptable to diversified requirements, yet capable to maintain a high level of trustworthiness. Using ABS, system variability is consistently traceable from the level of requirements engineering down to object behaviour. This facilitates temporal evolution, as changes to the required set of features of a system are automatically reflected by functional adaptation of the system’s behaviour. The analysis capabilities of ABS stretch from debugging, observing and simulating to resource analysis of ABS models and help ensure that a system will remain dependable throughout its evolutionary lifetime. We report on the experience of using the ABS language and the ABS tool suite in an industrial case study.

  The HATS project aims at developing a model-centric methodology for the design, implementation and verification of highly configurable systems, such as software product lines, centred around the Abstract Behavioural Specification (ABS) modelling Language. This article describes the variability modelling features of the ABS Modelling framework. It consists of four languages, namely, μTVL for describing feature models at a high level of abstraction, the Delta Modelling Language DML for describing variability of the ‘code’ base in terms of delta modules, the Product Line Configuration Language CL for linking feature models and delta modules together and the Product Selection Language PSL for describing a specific product to extract from a product line. Both formal semantics and examples of each language are presented.

  This paper describes the semantics of a timed, resource-constrained extension of the Creol modeling language. Creol is an object-oriented modeling language with a design that is suited for modeling distributed systems. However, the computation model of Creol assumes infinite memory and infinite parallelism within an object. This paper describes a way to extend Creol with a notion of resource constraints and a way to quantitatively assess the effects of introducing resource constraints on a given model. We discuss possible semantics of message delivery under resource constraints, their implementation and their impact on the model. The method is illustrated with a case study modeling a biomedical sensor network.

  We validate a Creol model of AODV by evaluating functional properties using simulation and component testing. We define a structure for evaluating and validating models of wireless sensor networks, which we intend to use as a reference for future evaluations of algorithms.We use the categories of techniques, perspectives, arrangements and properties to structure the evaluation work. We show, by way of the AODV algorithm, how network simulations and component testing can be employed to evaluate a large list of properties. We also show which properties are most suited to be evaluated by which technique, perspective, and arrangement.
