“…Bruneau and Consel have recently proposed the DiaSim simulator [7], which targets applications based on sensors and actuators, deployed in physical environments, involving users. DiaSim enables the simulation of the application logic of such applications, but does not simulate the other components of a pervasive computing environment.…”

In this paper we illustrate a cost-effective softwarein-the-loop simulation methodology, which is particularly suitable for testing large-scale pervasive systems and applications. The main advantage of such an approach is that real code has to be deployed once, and a general-purpose simulation engine replicates it over virtual devices and environments as often as we wish. Our implementation of the proposed methodology is illustrated by means of the software-in-the-loop simulation of a peer-to-peer information sharing system, with real code running on simulated mobile nodes.

Context-aware mobile applications gain more and more influence on our daily life. Since mobile devices are equipped with various sensors to detect their environment, it is possible to receive and process information from beyond application and device borders. Within the development, these context-aware applications have to be verified to assure that they do not cause any failures. This contribution outlines challenges of testing context-aware mobile applications relating to their context factors and present our approach for a context simulator that provides support for modeling and simulation of context in different levels: physical and logical context, situations and scenarios. The simulator supports test case derivation and enables test case execution for several context sources as part of testing mobile applications

Stimuli-SoS: a model-based approach to derive stimuli generators for simulations of systems-of-systems software architectures

Background: Systems-of-systems (SoS) are alliances of independent and interoperable software-intensive systems. SoS often support critical domains, being required to exhibit a reliable operation, specially because people's safety relies on their services. In this direction, simulations enable the validation of different operational scenarios in a controlled environment, allowing a benchmarking of its response as well as revealing possible breaches that could lead to failures. However, simulations are traditionally manual, demanding a high level of human intervention, being costly and error-prone. A stimuli generator could aid in by continuously providing data to trigger a SoS simulation and maintaining its operation. Methods: We established a model-based approach termed Stimuli-SoS to support the creation of stimuli generators to be used in SoS simulations. Stimuli-SoS uses software architecture descriptions for automating the creation of such generators. Specifically, this approach transforms SoSADL, a formal architectural description language for SoS, into dynamic models expressed in DEVS, a simulation formalism. We carried out a case study in which Stimuli-SoS was used to automatically produce stimuli generators for a simulation of a flood monitoring SoS. Results:We run simulations of a SoS architectural configuration with 69 constituent systems, i.e., 42 sensors, 9 crowdsourcing systems, and 18 drones. Stimuli generators were automatically generated for each type of constituent. These stimuli generators were capable of receiving the input data from the database and generating the expected stimuli for the constituents, allowing to simulate constituent systems interoperations into the flood monitoring SoS. Using Stimuli-SoS, we simulated 38 days of flood monitoring in little more than 6 h. Stimuli generators correctly forwarded data to the simulation, which was able to reproduce 29 flood alerts triggered by the SoS during a flooding event. In particular, Stimuli-SoS is almost 65 times more productive than a manual approach to producing data for the same type of simulation. Conclusions: Our approach succeeded in automatically deriving a functional stimuli generator that can reproduce environmental conditions for simulating a SoS. In particular, we presented new contributions regarding productivity and automation for the use of a model-based approach in SoS engineering.
