“…There are many embedded systems and application domains where runtime variability can play a key role in order to support the "autonomic" condition (Kephart and Chess, 2003) and manage system capabilities autonomously and dynamically. For instance, sensor network system families that use context information can be represented using variability models to determine and manage those features that vary at runtime (Gámez et al, 2011).…”

“…DSPLs are often considered to be an engineering approach for realizing adaptive systems based on the MAPE-K loop . In this way, Gámez et al (2011) describe a feature model for WSNs under a SPL context, which uses also a MAPE-K (i.e., the MAPE loop with knowledge of the environment) adaptation mechanism. The family of middleware (FamiWare) for WSNs developed under the SPL aimed to support autonomic and dynamic reconfiguration of nodes for an optimal network functioning suggests the use of context variability to model context features and plans as two distinct branches in the feature model separated from those other features whose values are known at design time.…”

a b s t r a c tOver the last two decades, software product lines have been used successfully in industry for building families of systems of related products, maximizing reuse, and exploiting their variable and configurable options. In a changing world, modern software demands more and more adaptive features, many of them performed dynamically, and the requirements on the software architecture to support adaptation capabilities of systems are increasing in importance. Today, many embedded system families and application domains such as ecosystems, service-based applications, and self-adaptive systems demand runtime capabilities for flexible adaptation, reconfiguration, and post-deployment activities. However, as traditional software product line architectures fail to provide mechanisms for runtime adaptation and behavior of products, there is a shift toward designing more dynamic software architectures and building more adaptable software able to handle autonomous decision-making, according to varying conditions. Recent development approaches such as Dynamic Software Product Lines (DSPLs) attempt to face the challenges of the dynamic conditions of such systems but the state of these solution architectures is still immature. In order to provide a more comprehensive treatment of DSPL models and their solution architectures, in this research work we provide an overview of the state of the art and current techniques that, partially, attempt to face the many challenges of runtime variability mechanisms in the context of Dynamic Software Product Lines. We also provide an integrated view of the challenges and solutions that are necessary to support runtime variability mechanisms in DSPL models and software architectures.

“…There are also authors that have developed a feature model tool specific for WSANs [20]. In [21], the authors describe middleware services for the dynamic reconfiguration of a WSN. They use feature models extended with context parameters capable of triggering a set of pre-defined reconfiguration plans.…”

Runtime variability is a key technique for the success of Dynamic Software Product Lines (DSPLs), as certain application demand reconfiguration of system features and execution plans at runtime. In this emerging research work we address the problem of dynamic changes in feature models in sensor networks product families, where nodes of the network demand dynamic reconfiguration at post-deployment time.

In recent years, the Wireless Sensor Networks (WSNs) have become a useful mechanism to monitor physical phenomena in environments. The sensors that make part of these long-lived networks have to be reconfigured according to context changes in order to preserve the operation of the network. Such reconfigurations require to consider the distributed nature of the sensor nodes as well as their resource scarceness. Therefore, self-adaptations for WSNs have special requirements comparing with traditional information systems. In particular, the reconfiguration of the WSN requires a trade-off between critical dimensions for this kind of networks and devices, such as resource consumption or reconfiguration cost. Thus, in this paper, we propose to exploit Constraint-Satisfaction Problem (CSP) techniques in order to find a suitable configuration for self-adapting WSNs, modelled using a Dynamic Software Product Line (DSPL), when the context changes. We exploit CSP modeling to find a compromise between contradictory dimensions. To illustrate our approach, we use an Intelligent Transportation System scenario. This case study enables us to show the advantages of obtaining suitable and optimized configurations for self-adapting WSNs.
